Academy at Tolaria West

At the beginning of your end step, if you have no cards in hand, draw seven cards.
Whenever you roll chaos, discard your hand.

A face-up plane card that's turned face down becomes a new object with no relation to its previous existence. In particular, it loses all counters it may have had.

A plane card is treated as if its text box included "When you roll {PW}, put this card on the bottom of its owner's planar deck face down, then move the top card of your planar deck off that planar deck and turn it face up." This is called the "planeswalking ability."

Academy at Tolaria West's first ability has an "intervening 'if' clause." That means (1) the ability won't trigger at all unless you have no cards in hand as your end step begins, and (2) the ability will do nothing unless you have no cards in hand by the time it resolves.

If an ability of a plane refers to "you," it's referring to whoever the plane's controller is at the time, not to the player that started the game with that plane card in their deck. Many abilities of plane cards affect all players, while many others affect only the planar controller, so read each ability carefully.

If you discard your hand as a result of rolling {CHAOS}, Academy at Tolaria West's first ability will then trigger at the beginning of your end step (unless you planeswalk or somehow put a card in your hand before then).

The controller of a face-up plane card is the player designated as the "planar controller." Normally, the planar controller is whoever the active player is. However, if the current planar controller would leave the game, instead the next player in turn order that wouldn't leave the game becomes the planar controller, then the old planar controller leaves the game. The new planar controller retains that designation until they leave the game or a different player becomes the active player, whichever comes first.

At the beginning of your end step, if you have no cards in hand, draw seven cards.
Whenever chaos ensues, discard your hand.

Agyrem

Whenever a white creature is put into a graveyard from the battlefield, return it to the battlefield under its owner's control at the beginning of the next end step.
Whenever a nonwhite creature is put into a graveyard from the battlefield, return it to its owner's hand at the beginning of the next end step.
Whenever you roll chaos, creatures can't attack you until a player planeswalks.

A creature that caused either of Agyrem’s first two abilities to trigger will be returned at the beginning of the next end step even if it’s not a creature card. (For example, if it’s a Treetop Village.)

A face-up plane card that’s turned face down becomes a new object with no relation to its previous existence. In particular, it loses all counters it may have had.

A plane card is treated as if its text box included “When you roll {PW}, put this card on the bottom of its owner’s planar deck face down, then move the top card of your planar deck off that planar deck and turn it face up.” This is called the “planeswalking ability.”

Agyrem’s first ability will return a card to the battlefield only if it’s still in the graveyard by the time the delayed triggered ability resolves. Similarly, Agyrem’s second ability will return a card to its owner’s hand only if it’s still in the graveyard by the time the delayed triggered ability resolves.

Agyrem’s first and second abilities each set up a delayed triggered ability. These abilities will trigger at the beginning of the next end step even if Agyrem is no longer the face-up plane card.

If a creature is put into a graveyard from the battlefield, its last existence on the battlefield is checked to determine its color.

If a token creature is put into a graveyard from the battlefield, one of Agyrem’s first two abilities will trigger, but the token will cease to exist long before it would be returned somewhere.

If an ability of a plane refers to “you,” it’s referring to whoever the plane’s controller is at the time, not to the player that started the game with that plane card in their deck. Many abilities of plane cards affect all players, while many others affect only the planar controller, so read each ability carefully.

If multiple creatures are put into their owners’ graveyards at the same time (due to combat damage or Planar Cleansing, for example), Agyrem’s first two abilities trigger that many times. At the beginning of the next end step, the player whose turn it is at that time puts all of their Agyrem delayed triggered abilities on the stack in any order, then each other player in turn order does the same. The last ability put on the stack is the first one that resolves. The creatures are returned one at a time.

If you’re affected by the chaos ability, creatures will still be able to attack planeswalkers you control.

The controller of a face-up plane card is the player designated as the “planar controller.” Normally, the planar controller is whoever the active player is. However, if the current planar controller would leave the game, instead the next player in turn order that wouldn’t leave the game becomes the planar controller, then the old planar controller leaves the game. The new planar controller retains that designation until they leave the game or a different player becomes the active player, whichever comes first.

Whenever a white creature dies, return it to the battlefield under its owner's control at the beginning of the next end step.
Whenever a nonwhite creature dies, return it to its owner's hand at the beginning of the next end step.
Whenever chaos ensues, creatures can't attack you until a player planeswalks.

Bant

All creatures have exalted. (Whenever a creature attacks alone, it gets +1/+1 until end of turn for each instance of exalted among creatures its controller controls.)
Whenever you roll chaos, put a divinity counter on target green, white, or blue creature. That creature is indestructible as long as it has a divinity counter on it.

Exalted abilities will resolve before blockers are declared.

Exalted bonuses last until the turn ends. If an effect creates an additional combat phase during your turn, a creature that attacked alone during the first combat phase will still have its exalted bonuses in that new phase. If a creature attacks alone during the second combat phase, all your exalted abilities will trigger again.

If you attack with multiple creatures, but then all but one are removed from combat, your exalted abilities won’t trigger.

If you declare exactly one creature as an attacker, each exalted ability on each permanent you control (including, perhaps, the attacking creature itself) will trigger. Note that if a creature has multiple instances of exalted, each one triggers separately. The bonuses are given to the attacking creature, not to the permanent with exalted. Ultimately, the attacking creature will wind up with +1/+1 for each of your exalted abilities.

In a Two-Headed Giant game, a creature “attacks alone” if it’s the only creature declared as an attacker by your entire team. If you control that attacking creature, your exalted abilities will trigger but your teammate’s exalted abilities won’t.

Some effects put creatures onto the battlefield attacking. Since those creatures were never declared as attackers, they’re ignored by exalted abilities. They won’t cause exalted abilities to trigger. If any exalted abilities have already triggered (because exactly one creature was declared as an attacker), those abilities will resolve as normal even though there may now be multiple attackers.

A creature with a divinity counter put on it due to the chaos ability retains indestructible even after Bant stops being the face-up plane card.

If all divinity counters on a creature are moved to a different creature, the indestructible ability doesn’t move along with them. The first creature no longer has indestructible because it no longer has a divinity counter on it. The second creature doesn’t have indestructible because the chaos ability didn’t target it.

All creatures have exalted. (Whenever a creature attacks alone, it gets +1/+1 until end of turn for each instance of exalted among permanents its controller controls.)
Whenever chaos ensues, put a divinity counter on target green, white, or blue creature. That creature has indestructible for as long as it has a divinity counter on it.

Cliffside Market

When you planeswalk to Cliffside Market or at the beginning of your upkeep, you may exchange life totals with target player.
Whenever you roll chaos, exchange control of two target permanents that share a type.

Both permanents targeted by the chaos ability may be controlled by the same player. If they are, the effect nothing.

For two players to exchange life totals, what actually happens is that each player gains or loses the amount of life necessary to equal the other player’s previous life total. For example, if Player A has 5 life and Player B has 3 life before the exchange, Player A will lose 2 life and Player B will gain 2 life. Other cards that interact with life gain or life loss will interact with this effect accordingly.

If either permanent targeted by the chaos ability is an illegal target by the time the ability resolves, the exchange doesn’t happen. If both targets become illegal, the ability doesn’t resolve.

Neither permanent you target with the chaos ability needs to be one you control.

The control-change effect has no duration. For each permanent, it will last until the game ends or the permanent leaves the battlefield. It will override all previous control-change effects for those permanents, and may be overridden by a later control-change effect.

When you planeswalk to Cliffside Market or at the beginning of your upkeep, you may exchange life totals with target player.
Whenever chaos ensues, exchange control of two target permanents that share a card type.

Eloren Wilds

Whenever a player taps a permanent for mana, that player adds one mana to his or her mana pool of any type that permanent produced.
Whenever you roll chaos, target player can't cast spells until a player planeswalks.

Eloren Wilds’s first ability affects any permanent players tap for mana, not just lands they tap for mana.

The additional mana is produced by Eloren Wilds, not the permanent that was tapped for mana.

The chaos ability prevents the affected player from casting permanent spells (artifacts, creatures, enchantments, and planeswalkers), not just instant and sorcery spells. It doesn’t stop the player from playing lands or activating abilities (such as cycling or unearth).

You’re “tapping a permanent for mana” only if you’re activating an activated ability of that permanent that includes the {T} symbol in its cost and produces mana as part of its effect.

Whenever a player taps a permanent for mana, that player adds one mana of any type that permanent produced.
Whenever chaos ensues, target player can't cast spells until a player planeswalks.

Feeding Grounds

Red spells cost {1} less to cast.
Green spells cost {1} less to cast.
Whenever you roll chaos, put X +1/+1 counters on target creature, where X is that creature's converted mana cost.

Spells that are both red and green cost {2} less to cast.

Red spells cost {1} less to cast.
Green spells cost {1} less to cast.
Whenever chaos ensues, put X +1/+1 counters on target creature, where X is that creature's mana value.

Fields of Summer

Whenever a player casts a spell, that player may gain 2 life.
Whenever you roll chaos, you may gain 10 life.

Whenever a player casts a spell, that player may gain 2 life.
Whenever chaos ensues, you may gain 10 life.

Glimmervoid Basin

Whenever a player casts an instant or sorcery spell with a single target, he or she copies that spell for each other spell, permanent, card not on the battlefield, and/or player the spell could target. Each copy targets a different one of them.
Whenever you roll chaos, choose target creature. Each player except that creature's controller puts a token onto the battlefield that's a copy of that creature.

A plane card is treated as if its text box included “When you roll {PW}, put this card on the bottom of its owner's planar deck face down, then move the top card of your planar deck off that planar deck and turn it face up.” This is called the “planeswalking ability.”

Anything that couldn't be targeted by the original spell (due to shroud, protection abilities, targeting restrictions, or any other reason) is just ignored by Glimmervoid Basin's first ability.

As a token is created by the chaos ability, it checks the printed values of the creature it's copying, as well as any copy effects that have been applied to it. It won't copy counters on the creature, nor will it copy other effects that have changed the creature's power, toughness, types, color, and so on.

If a spell targets multiple things, it won't cause Glimmervoid Basin's first ability to trigger, even if all but one of those targets has become illegal.

If a spell targets the same player or object multiple times, it won't cause Glimmervoid Basin's first ability to trigger.

If an ability of a plane refers to “you,” it's referring to whoever the plane's controller is at the time, not to the player that started the game with that plane card in their deck. Many abilities of plane cards affect all players, while many others affect only the planar controller, so read each ability carefully.

If the spell that's copied has an X whose value was determined as it was cast (like Earthquake does), the copy has the same value of X.

If the spell that's copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode. Its controller can't choose a different one.

Other than choices involving modes or additional costs, the copies are created based on what they could target if the spell were cast anew. For example, if a player casts Naturalize (“Destroy target artifact or enchantment”) targeting an artifact, Glimmervoid Basin's first ability will copy it for each artifact and enchantment it could target (and each copy will target a different one of those), not just for each artifact it could target.

The controller of a copy can't choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.

The controller of a face-up plane card is the player designated as the “planar controller.” Normally, the planar controller is whoever the active player is. However, if the current planar controller would leave the game, instead the next player in turn order that wouldn't leave the game becomes the planar controller, then the old planar controller leaves the game. The new planar controller retains that designation until they leave the game or a different player becomes the active player, whichever comes first.

The controller of the spell that caused Glimmervoid Basin's first ability to trigger also controls all the copies. That player chooses the order the copies are put onto the stack. The original spell will be on the stack beneath those copies and resolves last.

The copies that Glimmervoid Basin's first ability creates are created on the stack, so they're not “cast.” Abilities that trigger when a player casts a spell (like Glimmervoid Basin's first ability itself) won't trigger.

Whenever a player casts an instant or sorcery spell with a single target, that player copies that spell for each other spell, permanent, card not on the battlefield, and/or player the spell could target. Each copy targets a different one of them.
Whenever chaos ensues, choose target creature. Each player except that creature's controller creates a token that's a copy of that creature.

Goldmeadow

Whenever a land enters the battlefield, that land's controller puts three 0/1 white Goat creature tokens onto the battlefield.
Whenever you roll chaos, put a 0/1 white Goat creature token onto the battlefield.

Whenever a land enters the battlefield, that land's controller creates three 0/1 white Goat creature tokens.
Whenever chaos ensues, create a 0/1 white Goat creature token.

Grixis

Blue, black, and/or red creature cards in your graveyard have unearth. The unearth cost is equal to the card's mana cost. (Pay the card's mana cost: Return it to the battlefield. The creature gains haste. Exile it at the beginning of the next end step or if it would leave the battlefield. Unearth only as a sorcery.)
Whenever you roll chaos, put target creature card in a graveyard onto the battlefield under your control.

Activating a creature card’s unearth ability isn’t the same as casting the creature card. The unearth ability is put on the stack, but the creature card is not. Spells and abilities that interact with activated abilities (such as Stifle) will interact with unearth, but spells and abilities that interact with spells (such as Essence Scatter) will not.

At the beginning of the end step, a creature returned to the battlefield with unearth is exiled. This is a delayed triggered ability, and it can be countered by effects such as Stifle or Voidslime that counter triggered abilities. If the ability is countered, the creature will stay on the battlefield and the ability won’t trigger again. However, the replacement effect will still exile the creature if it would eventually leave the battlefield.

Despite the appearance of the reminder text, the unearth abilities that Grixis grants are activated abilities of each individual blue, black, and/or red creature card in a graveyard. They’re not activated abilities of Grixis.

Grixis may cause a creature card in a graveyard to have multiple unearth abilities. Its owner may activate any one of those abilities.

If a creature returned to the battlefield with unearth would leave the battlefield for any reason, it’s exiled instead — unless the spell or ability that’s causing the creature to leave the battlefield is actually trying to exile it! In that case, it succeeds at exiling it. If it later returns the creature card to the battlefield (as Oblivion Ring or Flickerwisp might, for example), the creature card will return to the battlefield as a new permanent with no relation to its previous existence. The unearth effect will no longer apply to it.

If you activate a creature card’s unearth ability but that card is removed from your graveyard before the ability resolves, that unearth ability will resolve and do nothing.

Unearth grants haste to the creature that’s returned to the battlefield. However, neither of the exile abilities is granted to that creature. If that creature loses all its abilities, it will still be exiled at the beginning of the end step, and if it would leave the battlefield, it is still exiled instead.

Unlike the unearth ability, the chaos ability returns a creature card from a graveyard to the battlefield indefinitely.

Blue, black, and/or red creature cards in your graveyard have unearth. The unearth cost is equal to the card's mana cost. (Pay the card's mana cost: Return it to the battlefield. The creature gains haste. Exile it at the beginning of the next end step or if it would leave the battlefield. Unearth only as a sorcery.)
Whenever chaos ensues, put target creature card from a graveyard onto the battlefield under your control.

Immersturm

Whenever a creature enters the battlefield, that creature's controller may have it deal damage equal to its power to target creature or player of his or her choice.
Whenever you roll chaos, exile target creature, then return it to the battlefield under its owner's control.

A token that has left the battlefield can’t come back onto the battlefield. If the chaos ability exiles a token, that token remains in exile until state-based actions are checked, then it ceases to exist.

Any “as [this permanent] enters the battlefield” choices for the card returned by the chaos ability are made by that card’s owner, not its old controller or the controller of the chaos ability.

If a creature controlled by a player other than the planar controller enters the battlefield, the planar controller (not the creature’s controller) controls Immersturm’s triggered ability. That means that if multiple creatures enter the battlefield at the same time, that player controls all of Immersturm’s triggered abilities and may put them on the stack in whichever order they like. The last one put on the stack is the first one to resolve.

When the chaos ability resolves, the targeted creature is exiled, then immediately returned to the battlefield as a new permanent with no relation to its previous existence.

Whenever a creature enters the battlefield, that creature's controller may have it deal damage equal to its power to any target of their choice.
Whenever chaos ensues, exile target creature, then return it to the battlefield under its owner's control.

Isle of Vesuva

Whenever a nontoken creature enters the battlefield, its controller puts a token onto the battlefield that's a copy of that creature.
Whenever you roll chaos, destroy target creature and all other creatures with the same name as that creature.

A face-down creature has no name, so it doesn't have the same name as anything else.

A token's name is the same as the creature types listed by the effect that created it, unless the token copies a permanent or that effect specifically gives that token a name. For example, the effect of The Fourth Sphere's chaos ability creates a token with the name “Zombie.”

As a token is created by Isle of Vesuva's first ability, it checks the printed values of the creature it's copying, as well as any copy effects that have been applied to it. It won't copy counters on the creature, nor will it copy other effects that have changed the creature's power, toughness, types, color, and so on.

If the creature that caused Isle of Vesuva's first ability to trigger has already left the battlefield by the time the ability resolves, the ability still creates a token. It will have the copiable values of the characteristics of that nontoken creature as it last existed on the battlefield.

If the permanent targeted by the chaos ability has become an illegal target by the time the ability resolves, the ability doesn't resolve. Nothing will be destroyed.

The chaos ability will destroy all creatures with the same name as the target creature, not just tokens created by Isle of Vesuva's first ability. It doesn't matter who controls them.

If the permanent targeted by the chaos ability isn't destroyed (because it regenerates, or because it has indestructible), all other permanents with the same name as it will still be destroyed.

Whenever a nontoken creature enters the battlefield, its controller creates a token that's a copy of that creature.
Whenever chaos ensues, destroy target creature and all other creatures with the same name as that creature.

Izzet Steam Maze

Whenever a player casts an instant or sorcery spell, that player copies it. The player may choose new targets for the copy.
Whenever you roll chaos, instant and sorcery spells you cast this turn cost {3} less to cast.

A copy is created even if the spell that caused Izzet Steam Maze’s first ability to trigger has been countered by the time that ability resolves.

If the spell that’s copied has an X whose value was determined as it was cast (like Earthquake does), the copy has the same value of X.

If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode. Its controller can’t choose a different one.

Izzet Steam Maze’s first ability will copy any instant or sorcery spell, not just one with targets.

The controller of the copy can’t choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.

The controller of the spell that caused Izzet Steam Maze’s first ability to trigger also controls the copy. The copy resolves before the original spell.

The copy that Izzet Steam Maze’s first ability creates is created on the stack, so it’s not “cast.” Abilities that trigger when a player casts a spell (like Izzet Steam Maze’s first ability itself) won’t trigger.

The copy will have the same targets as the spell it’s copying unless its controller chooses new ones. That player may change any number of the targets, including all of them or none of them. The new targets must be legal.

The effect of Izzet Steam Maze’s first ability is mandatory. You must copy the spell whether you want to or not.

Whenever a player casts an instant or sorcery spell, that player copies it. The player may choose new targets for the copy.
Whenever chaos ensues, instant and sorcery spells you cast this turn cost {3} less to cast.

Krosa

All creatures get +2/+2.
Whenever you roll chaos, you may add {W}{U}{B}{R}{G} to your mana pool.

All creatures get +2/+2.
Whenever chaos ensues, you may add {W}{U}{B}{R}{G}.

Lethe Lake

At the beginning of your upkeep, put the top ten cards of your library into your graveyard.
Whenever you roll chaos, target player puts the top ten cards of his or her library into his or her graveyard.

If you don’t have ten cards in your library, you’ll put all the cards in your library into your graveyard. The same is true if the targeted player doesn’t have ten cards in their library.

At the beginning of your upkeep, mill ten cards.
Whenever chaos ensues, target player mills ten cards.

Llanowar

All creatures have "{T}: Add {G}{G} to your mana pool."
Whenever you roll chaos, untap all creatures you control.

All creatures have "{T}: Add {G}{G}."
Whenever chaos ensues, untap all creatures you control.

Minamo

Whenever a player casts a spell, that player may draw a card.
Whenever you roll chaos, each player may return a blue card from his or her graveyard to his or her hand.

Minamo’s first ability resolves before the spell that caused it to trigger.

The chaos ability doesn’t target the cards it will return, so they’re not chosen until resolution. As the ability resolves, first the active player may choose a blue card in their graveyard, then each other player in turn order does the same, then all cards chosen this way are returned to their owners’ hands. Once a card is chosen, it’s too late for players to respond.

Whenever a player casts a spell, that player may draw a card.
Whenever chaos ensues, each player may return a blue card from their graveyard to their hand.

Murasa

Whenever a nontoken creature enters the battlefield, its controller may search his or her library for a basic land card, put it onto the battlefield tapped, then shuffle his or her library.
Whenever you roll chaos, target land becomes a 4/4 creature that's still a land.

The effect of the chaos ability has no duration. The affected land will remain a creature until the end of the game, it leaves the battlefield, or some other effect changes its card types, whichever comes first. It doesn’t matter whether Murasa remains the face-up plane card.

Whenever a nontoken creature enters the battlefield, its controller may search their library for a basic land card, put it onto the battlefield tapped, then shuffle.
Whenever chaos ensues, target land becomes a 4/4 creature that's still a land.

Naar Isle

At the beginning of your upkeep, put a flame counter on Naar Isle, then Naar Isle deals damage to you equal to the number of flame counters on it.
Whenever you roll chaos, Naar Isle deals 3 damage to target player.

At the beginning of your upkeep, put a flame counter on Naar Isle, then Naar Isle deals damage to you equal to the number of flame counters on it.
Whenever chaos ensues, Naar Isle deals 3 damage to target player or planeswalker.

Naya

You may play any number of additional lands on each of your turns.
Whenever you roll chaos, target red, green, or white creature you control gets +1/+1 until end of turn for each land you control.

If you play lands using Naya’s first ability, and then you planeswalk away from Naya, the lands you played still count as additional land plays for the turn. If you haven’t already, you can still play a land using your standard land play.

The bonus granted by the chaos ability is determined at the time it resolves. It won’t change if the number of lands you control changes later in the turn.

You may play any number of lands on each of your turns.
Whenever chaos ensues, target red, green, or white creature you control gets +1/+1 until end of turn for each land you control.

Otaria

Instant and sorcery cards in graveyards have flashback. The flashback cost is equal to the card's mana cost. (Its owner may cast the card from his or her graveyard for its mana cost. Then he or she exiles it.)
Whenever you roll chaos, take an extra turn after this one.

As a spell cast with flashback resolves, it never goes to its owner’s graveyard, so abilities that trigger on cards being put in a graveyard won’t trigger. The card is exiled instead.

If a spell cast by using flashback is countered, it’s still exiled rather than being put into its owner’s graveyard.

If you cast a card by using flashback, you cast that card from your graveyard rather than your hand, and you pay an alternative cost rather than its mana cost, but everything else about casting that spell works normally. You must follow timing restrictions based on the card’s type (if it’s a sorcery), as well as other restrictions (such as “Cast [this card] only before blockers are declared”). You may pay additional costs (such as kicker). Effects that cause you to pay more or less for a spell will apply.

If you roll {CHAOS} multiple times in the same turn, you’ll take that many extra turns after this one.

If you use a card’s flashback ability, you’re actually casting that card. It moves from your graveyard to the stack. Abilities that trigger when you cast a spell will trigger. That spell can be countered.

If you use the flashback ability granted by Otaria to cast a card with X in its mana cost from your graveyard, you choose the value of X as you cast it. You’ll still have to pay that X.

If you use the flashback ability granted by Otaria to cast a split card from your graveyard, the flashback cost you pay is equal to the mana cost of the half that you’re casting.

Otaria may cause an instant or sorcery card in a graveyard to have multiple flashback abilities. Its owner may cast it using any one of those abilities.

Instant and sorcery cards in graveyards have flashback. The flashback cost is equal to the card's mana cost. (Its owner may cast the card from their graveyard for its mana cost. Then they exile it.)
Whenever chaos ensues, take an extra turn after this one.

Panopticon

When you planeswalk to Panopticon, draw a card.
At the beginning of your draw step, draw an additional card.
Whenever you roll chaos, draw a card.

When you planeswalk to Panopticon, draw a card.
At the beginning of your draw step, draw an additional card.
Whenever chaos ensues, draw a card.

Pools of Becoming

At the beginning of your end step, put the cards in your hand on the bottom of your library in any order, then draw that many cards.
Whenever you roll chaos, reveal the top three cards of your planar deck. Each of the revealed cards' chaos abilities triggers. Then put the revealed cards on the bottom of your planar deck in any order.

If one of the revealed plane cards is another Pools of Becoming, its chaos ability triggers. When it resolves, you’ll reveal three more cards from the top of your planar deck, their chaos abilities will trigger, and you’ll put them on the stack in any order on top of any remaining chaos abilities from the first Pools of Becoming’s effect.

The face-up plane card isn’t currently part of its owner’s planar deck. If the chaos ability is rolled by the owner of Pools of Becoming, Pools of Becoming is not one of the three cards that are revealed.

You may put the chaos abilities of the three revealed plane cards on the stack in any order. The last one you put on the stack will be the first one to resolve.

At the beginning of your end step, put the cards in your hand on the bottom of your library in any order, then draw that many cards.
Whenever chaos ensues, reveal the top three cards of your planar deck. Each of the revealed cards' {CHAOS} abilities triggers. Then put the revealed cards on the bottom of your planar deck in any order.

Raven's Run

All creatures have wither. (They deal damage to creatures in the form of -1/-1 counters.)
Whenever you roll chaos, put a -1/-1 counter on target creature, two -1/-1 counters on another target creature, and three -1/-1 counters on a third target creature.

Damage from creatures with wither affects players and planeswalkers normally.

If the source of the damage is still on the battlefield at the time that damage is dealt, its characteristics are checked to see if it has wither. If the source has left the battlefield by then, its last existence on the battlefield is checked to see if it had wither.

Multiple instances of wither are redundant.

Since damage from a creature with wither is real damage, it follows all the other rules for damage. It can be prevented or redirected. When it’s dealt, it will cause “Whenever [this creature] deals damage” and “Whenever [this creature] is dealt damage” abilities to trigger.

The -1/-1 counters that result from wither remain on the damaged creature indefinitely. They won’t be removed if the creature regenerates or the turn ends.

Wither applies to any damage, not just combat damage.

You must target three different creatures when the chaos ability triggers, even if that means you have to target creatures you control. If you can’t target three creatures (because there are just two creatures on the battlefield, perhaps), the ability is removed from the stack and does nothing.

All creatures have wither. (They deal damage to creatures in the form of -1/-1 counters.)
Whenever chaos ensues, put a -1/-1 counter on target creature, two -1/-1 counters on another target creature, and three -1/-1 counters on a third target creature.

Sanctum of Serra

When you planeswalk away from Sanctum of Serra, destroy all nonland permanents.
Whenever you roll chaos, you may have your life total become 20.

For a player’s life total to become 20, what actually happens is that the player gains or loses the appropriate amount of life. For example, if your life total is 14 when this ability resolves, it will cause you to gain 6 life. Other cards that interact with life gain or life loss will interact with this effect accordingly.

If you planeswalk away from Sanctum of Serra because the player who owns Sanctum of Serra leaves the game, its first ability will still trigger and resolve.

When you planeswalk away from Sanctum of Serra, destroy all nonland permanents.
Whenever chaos ensues, you may have your life total become 20.

Sea of Sand

Players reveal each card they draw.
Whenever a player draws a land card, that player gains 3 life.
Whenever a player draws a nonland card, that player loses 3 life.
Whenever you roll chaos, put target permanent on top of its owner's library.

Players reveal each card they draw.
Whenever a player draws a land card, that player gains 3 life.
Whenever a player draws a nonland card, that player loses 3 life.
Whenever chaos ensues, put target permanent on top of its owner's library.

Shiv

All creatures have "{R}: This creature gets +1/+0 until end of turn."
Whenever you roll chaos, put a 5/5 red Dragon creature token with flying onto the battlefield.

All creatures have "{R}: This creature gets +1/+0 until end of turn."
Whenever chaos ensues, create a 5/5 red Dragon creature token with flying.

Skybreen

Players play with the top card of their libraries revealed.
Spells that share a card type with the top card of a library can't be cast.
Whenever you roll chaos, target player loses life equal to the number of cards in his or her hand.

If the top card of your library changes during the process of casting a spell or activating an ability, the new top card won’t be revealed until the process of casting the spell or activating the ability ends (all targets are chosen, all costs are paid, and so on).

Skybreen’s second ability prevents each player from casting spells that share a card type with a card on top of any library, not just the one on top of that player’s own library. This includes permanent spells (artifacts, creatures, enchantments, and planeswalkers), not just instant and sorcery spells. It doesn’t stop players from playing lands or activating abilities (such as cycling or unearth).

When playing with the top card of your library revealed, if an effect tells you to draw several cards, reveal each one before you draw it.

Sokenzan

All creatures get +1/+1 and have haste.
Whenever you roll chaos, untap all creatures that attacked this turn. After this main phase, there is an additional combat phase followed by an additional main phase.

If you roll {CHAOS} twice in the same main phase, two new combat phases will be created. However, all creatures that attacked this turn untap as the chaos abilities resolve, not as the combat phases start. Any creature that attacks in the second combat phase will remain tapped during the third combat phase (unless you roll {CHAOS} again).

Stronghold Furnace

If a source would deal damage to a creature or player, it deals double that damage to that creature or player instead.
Whenever you roll chaos, Stronghold Furnace deals 1 damage to target creature or player.

If a spell or ability divides damage among multiple recipients (such as Pyrotechnics does), the damage is divided before Stronghold Furnace's effect doubles it. The same is true for combat damage.

If multiple effects modify how damage will be dealt, the player who would be dealt damage or the controller of the creature that would be dealt damage chooses the order to apply the effects. For example, Mending Hands says, “Prevent the next 4 damage that would be dealt to any target this turn.” Suppose a spell would deal 5 damage to a player who has cast Mending Hands targeting themselves. The player who would be dealt damage can either (a) prevent 4 damage first and then let Stronghold Furnace's effect double the remaining 1 damage, taking 2 damage, or (b) double the damage to 10 and then prevent 4 damage, taking 6 damage.

Stronghold Furnace's first ability interacts with all damage, not just combat damage. Notably, it doubles the damage from its own chaos ability.

If a source would deal damage to a permanent or player, it deals double that damage instead.
Whenever chaos ensues, Stronghold Furnace deals 1 damage to any target.

The Aether Flues

When you planeswalk to The Æther Flues or at the beginning of your upkeep, you may sacrifice a creature. If you do, reveal cards from the top of your library until you reveal a creature card, put that card onto the battlefield, then shuffle all other cards revealed this way into your library.
