The Invasion Tree broke through the Blind Eternities and sent Phyrexian perfection coursing across the Multiverse.

All Will Be One

All Will Be One's ability will trigger any time you put one or more counters on a permanent or player. This might be due to a spell or ability resolving, a permanent you control entering the battlefield with counters, or combat damage from a source with toxic, infect, or wither.

If more than one creature with toxic deals combat damage to a player at the same time, those counters are placed as a single event, and the ability triggers one time.

Whenever you put one or more counters on a permanent or player, All Will Be One deals that much damage to target opponent, creature an opponent controls, or planeswalker an opponent controls.

Archfiend of the Dross

If Archfiend of the Dross is no longer on the battlefield as its upkeep triggered ability resolves, use the number of oil counters it had the last time it existed on the battlefield to determine whether you lose the game. You can't remove oil counters from it if it's not on the battlefield, so you won't lose the game if it had only one oil counter on it before leaving the battlefield.

If Archfiend of the Dross somehow loses all of its oil counters due to an effect other than its upkeep triggered ability, this won't cause you to lose the game until the next time that ability resolves.

Flying
Archfiend of the Dross enters with four oil counters on it.
At the beginning of your upkeep, remove an oil counter from Archfiend of the Dross. Then if it has no oil counters on it, you lose the game.
Whenever a creature an opponent controls dies, its controller loses 2 life.

Argentum Masticore

Notably, this means that you may discard a card to keep Argentum Masticore on the battlefield even if there isn't a legal target for that second triggered ability. In that case, no players may respond to the second triggered ability and it does not resolve.

You don't choose a target for Argentum Masticore's upkeep triggered ability at the time it triggers. Rather, a second "reflexive" ability triggers when you discard a card this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.

First strike, protection from multicolored
At the beginning of your upkeep, sacrifice Argentum Masticore unless you discard a card. When you discard a card this way, destroy target nonland permanent an opponent controls with mana value less than or equal to the mana value of the discarded card.

Atraxa, Grand Unifier

At the time of this document's publication, it is exceedingly unlikely you will reveal a battle this way. This likelihood will change over time.

If a revealed card has more than one card type, you may choose to put it into your hand for any of its types. For example, an artifact creature card could be put into your hand as the artifact card you choose or as the creature card you choose. If you choose it as the artifact card, you could also put into your hand a creature card, and vice versa.

Flying, vigilance, deathtouch, lifelink
When Atraxa, Grand Unifier enters, reveal the top ten cards of your library. For each card type, you may put a card of that type from among the revealed cards into your hand. Put the rest on the bottom of your library in a random order. (Artifact, battle, creature, enchantment, instant, land, planeswalker, and sorcery are card types.)

"Where once there was complacence, Sheoldred brought ambition, and soon the will of Yawgmoth reigned."
—Monument inscription

Black Sun's Twilight

The creature card you return, if any, isn't a target of Black Sun's Twilight. You choose it as Black Sun's Twilight resolves if X is 5 or more.

You can cast Black Sun's Twilight without a target (presumably with X equal to 5 or more) just to return a creature card. However, if you do choose a target, and that target is illegal at the time the spell tries to resolve, the spell won't resolve and none of its effects will happen. You won't get to return a creature card to the battlefield.

Up to one target creature gets -X/-X until end of turn. If X is 5 or more, return a creature card with mana value X or less from your graveyard to the battlefield tapped.

Where ambition meets industry, passion is poisoned by greed.

Blackcleave Cliffs

If one of these lands enters the battlefield at the same time as one or more other lands (due to Oblivion Sower or Warp World, perhaps), it doesn't take those lands into consideration when determining how many other lands you control.

If one of these lands enters the battlefield under your control and you control zero, one, or two other lands, it enters the battlefield untapped. If you control three or more other lands, it enters the battlefield tapped.

Blackcleave Cliffs enters tapped unless you control two or fewer other lands.
{T}: Add {B} or {R}.

Blade of Shared Souls

If the Rebel is destroyed, the Equipment stays on the battlefield. Similarly, you may pay its equip cost to move it from the Rebel token to another creature you control.

If the ability causes two Rebel tokens to be created (due to an effect such as that of Mondrak, Glory Dominus), the Equipment becomes attached to only one of them.

If the target creature is a double-faced or melded permanent, the equipped creature copies the face shown. If the equipped creature copies a melded permanent or the back face of a double-faced card, its mana value is 0.

If the target creature is a token, the equipped creature copies the original characteristics of that token as stated by the effect that created it. If the equipped creature isn't a token, copying a token won't cause it to become a token. Similarly, if the equipped creature is a token, copying a nontoken won't cause it to become a nontoken.

If the target creature is copying something else (for example, if that creature is equipped by another Blade of Shared Souls), then the equipped creature becomes a copy of whatever the target creature copied.

If the target creature isn't normally a creature (for example, an animated Monument to Perfection), the equipped creature will become a copy of the noncreature permanent. Blade of Shared Souls will become unattached and the copy effect will end. The previously equipped creature will revert to whatever it was before the copy effect applied.

Non-copy effects that have already applied to the equipped creature will continue to apply to it. For example, +1/+1 counters on it will still affect it.

The Rebel enters the battlefield as a 2/2 creature, then the Equipment becomes attached to it. Abilities that trigger when a creature enters the battlefield see that a 2/2 creature entered the battlefield.

The copiable values granted by Blade of Shared Souls are locked in as its effect begins to apply. After that point, it doesn't matter if the creature that's being copied leaves the battlefield or if any of its copiable values change.

The creature copies exactly what is printed on the chosen creature (unless that creature has additional copy effects affecting it, is copying something else, or is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or any Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on.

For Mirrodin! (When this Equipment enters, create a 2/2 red Rebel creature token, then attach this to it.)
Whenever Blade of Shared Souls becomes attached to a creature, for as long as Blade of Shared Souls remains attached to it, you may have that creature become a copy of another target creature you control.
Equip {2}

Bloated Contaminator

A player with ten or more poison counters loses the game. This is a state-based action and doesn't use the stack. In other words, it happens immediately and players can't respond to it, just like a player losing the game due to having 0 or less life.

An ability that triggers "Whenever you proliferate" triggers even if you chose no permanents or players while doing so.

Any other effects of that damage, such as life gain from lifelink, still apply.

Conversely, replacement effects that apply to the number of counters put on a player can modify the counters placed this way. For example, Vorinclex, Monstrous Raider's last two abilities can apply to counters placed this way.

Damage dealt by a creature with toxic grants the same number of counters regardless of how much damage is dealt. Notably, if a replacement effect modifies the damage in some way (such as that of Gratuitous Violence), the number of counters given remains unchanged.

If a creature with toxic deals combat damage to a creature or planeswalker, or if it deals noncombat damage, toxic has no effect and no player gets poison counters.

If a permanent ever has both +1/+1 counters and -1/-1 counters on it at the same time, they're removed in pairs as a state-based action so that the permanent has only one of those kinds of counters on it.

If a player or permanent has more than one kind of counter on it, and you choose for it to get additional counters, it must get one of each kind of counter it already has. You can't have it get just one kind of counter it already has and not the others.

Multiple instances of toxic are cumulative. For example, if a creature has toxic 2 and gains toxic 1 due to another effect, combat damage that creature deals to a player will cause that player to get 3 poison counters.

Players can respond to a spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it's too late for anyone to respond.

To proliferate, you can choose any permanent that has a counter, including ones controlled by opponents. You can choose any player who has a counter, including opponents. You can't choose cards in any zone other than the battlefield, even if they have counters on them.

Toxic doesn't change the amount of combat damage a creature deals. For example, if a 2/2 creature with toxic 1 deals combat damage to a player, that creature will deal 2 damage. The results of that damage are the player loses 2 life and gets a poison counter.

You don't have to choose every permanent or player that has a counter, only the ones you want to add another counter to. Since "any number" includes zero, you don't have to choose any permanents at all, and you don't have to choose any players at all.

Trample
Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
Whenever Bloated Contaminator deals combat damage to a player, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

"Where once there was ignorance, Jin-Gitaxias brought knowledge, and an age of progress dawned."
—Monument inscription

Blue Sun's Twilight

If the target creature is an illegal target by the time the spell tries to resolve, the spell will not resolve. No token is created, even if X is 5 or more.

Gain control of target creature with mana value X or less. If X is 5 or more, create a token that's a copy of that creature.

Capricious Hellraiser

If the spell you cast has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

If you cast a spell "without paying its mana cost," you can't pay any alternative costs. You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, you must pay those.

If you don't want to cast the copy, you can choose not to; the copy ceases to exist the next time state-based actions are checked.

The three cards you exile are chosen at random from among all cards in your graveyard. If all three cards you exile this way are creature and/or land cards, you won't be able to choose one of them to copy and cast. Capricious, indeed.

You cast the copy while the ability is resolving and still on the stack. You can't wait to cast it later in the turn.

This spell costs {3} less to cast if you have nine or more cards in your graveyard.
Flying
When Capricious Hellraiser enters, exile three cards at random from your graveyard. Choose a noncreature, nonland card from among them and copy it. You may cast the copy without paying its mana cost.

Conduit of Worlds

The first ability of Conduit of Worlds doesn't change the times when you can play those land cards. You can still play only one land per turn, and only during your main phase when you have priority and the stack is empty.

The second ability of Conduit of Worlds allows you to cast the target card as the ability resolves. You can't wait and cast that card later in the turn. If you cast it, you can't cast any other spells this turn, even if another effect would allow you to.

The second ability of Conduit of Worlds will count spells you cast earlier in the turn even if Conduit of Worlds wasn't on the battlefield or under your control at that time. It will also count a spell you cast that subsequently was countered or failed to resolve. Notably, it will also include Conduit of Worlds itself on the turn you cast it.

You may play lands from your graveyard.
{T}: Choose target nonland permanent card in your graveyard. If you haven't cast a spell this turn, you may cast that card. If you do, you can't cast additional spells this turn. Activate only as a sorcery.

Where fire meets ferocity, a greater evolution begins.

Copperline Gorge

If one of these lands enters the battlefield under your control and you control zero, one, or two other lands, it enters the battlefield untapped. If you control three or more other lands, however, it enters the battlefield tapped.

Copperline Gorge enters tapped unless you control two or fewer other lands.
{T}: Add {R} or {G}.

Where curiosity meets cruelty, hideous innovations arise.

Darkslick Shores

Darkslick Shores enters tapped unless you control two or fewer other lands.
{T}: Add {U} or {B}.

Dragonwing Glider

For Mirrodin! (When this Equipment enters, create a 2/2 red Rebel creature token, then attach this to it.)
Equipped creature gets +2/+2 and has flying and haste.
Equip {3}{R}{R}

Drivnod, Carnage Dominus

A nontoken creature dying will cause an ability of a permanent that triggers whenever a card is put into a graveyard "from anywhere" to trigger twice only if Drivnod and that permanent are both still on the battlefield immediately after the creature has died.

An ability that triggers on an event that causes a creature to die doesn't trigger twice. For example, an ability that triggers "whenever you sacrifice a creature" triggers only once.

An ability that triggers when a creature "leaves the battlefield" will trigger twice if that creature leaves the battlefield by dying.

Drivnod affects a creature's own "when this creature dies" triggered abilities as well as other triggered abilities that trigger when that creature dies. Such triggered abilities start with "when" or "whenever."

Drivnod's effect doesn't copy the triggered ability; it just causes the ability to trigger twice. Any choices made as you put the ability onto the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution, such as whether to pay a cost for that triggered ability, are also made separately.

If a creature dying at the same time as Drivnod (including Drivnod itself dying) causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

If a creature dying at the same time that another permanent you control leaves the battlefield causes a triggered ability of that permanent to trigger, that ability triggers an additional time.

If you somehow control two Drivnods, a creature dying causes abilities to trigger three times, not four. A third Drivnod causes abilities to trigger four times, a fourth causes abilities to trigger five times, and so on. This also means that if you control Drivnod and cast a second one, an ability that triggers when it dies due to the "legend rule" triggers three times.

Look at each creature as it exists on the battlefield, taking into account continuous effects, to determine whether any triggered abilities will trigger multiple times. For example, if a land that has become a creature dies, an ability that triggers when it dies triggers twice.

The trigger event doesn't have to specifically refer to "creatures." In these cases, the trigger event may also refer to something being "put into a graveyard from the battlefield." For example, an ability that triggers "whenever an artifact is put into a graveyard from the battlefield" would trigger twice if an artifact creature dies while Drivnod, Carnage Dominus is on the battlefield.

If a creature dying causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.
{B/P}{B/P}, Exile three creature cards from your graveyard: Put an indestructible counter on Drivnod, Carnage Dominus. ({B/P} can be paid with either {B} or 2 life.)

Elesh Norn, Mother of Machines

Abilities that apply "as [this permanent] enters the battlefield," such as choosing a card type with Stenn, Paranoid Partisan, are also unaffected.

Elesh Norn's abilities don't look at who controls the permanent entering the battlefield, only who controls the permanent that has the triggered ability. For example, if you control Elesh Norn and a permanent with the ability "Whenever a creature enters the battlefield, you gain 1 life," a creature entering the battlefield under an opponent's control will cause that ability to trigger twice.

Elesh Norn's first ability doesn't copy the triggered ability; it just causes the ability to trigger twice. Any choices made as you put the ability onto the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution, such as whether to put counters on a permanent, are also made individually.

Elesh Norn's second and third ability each affects a permanent's own enters-the-battlefield triggered abilities as well as other triggered abilities that trigger when that permanent enters the battlefield. Such triggered abilities start with "when" or "whenever." Some keyword abilities also include a triggered ability that happens when a permanent enters the battlefield, such as For Mirrodin!

If a permanent entering the battlefield at the same time as Elesh Norn (including Elesh Norn itself) causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

If a triggered ability is linked to a second ability, additional instances of that triggered ability are also linked to that second ability. If the second ability refers to "the exiled card," it refers to all cards exiled by instances of the triggered ability.

If you somehow control two Elesh Norns, a permanent entering the battlefield causes abilities to trigger three times, not four. A third Elesh Norn causes abilities to trigger four times, a fourth causes abilities to trigger five times, and so on.

In a Two-Headed Giant game, Elesh Norn does not affect triggered abilities of permanents your teammate controls.

In some cases involving linked abilities, an ability requires information about "the exiled card." When this happens, the ability gets multiple answers. If these answers are being used to determine the value of a variable, the sum is used. For example, if Elite Arcanist's enters-the-battlefield ability triggers twice, two cards are exiled. The value of X in the activation cost of Elite Arcanist's other ability is the sum of the two cards' mana values. As the ability resolves, you create copies of both cards and can cast none, one, or both of the copies in any order.

Replacement effects are unaffected by Elesh Norn's abilities. For example, a creature that enters the battlefield under your control with one +1/+1 counter on it won't receive an additional +1/+1 counter.

Similarly, a permanent entering the battlefield at the same time as Elesh Norn (still including Elesh Norn) won't cause abilities of permanents an opponent controls to trigger.

Vigilance
If a permanent entering causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.
Permanents entering don't cause abilities of permanents your opponents control to trigger.

"Careful—however they might look, they're not human. A step too close and they'll drag you in."

Encroaching Mycosynth

Encroaching Mycosynth turns all permanents you control into artifacts. Permanent spells you control become artifact spells in addition to their other types, and nonland permanent cards you own in other zones become artifact cards in addition to their other types.

Encroaching Mycosynth's ability causes Auras to become artifacts. This makes it more likely that another effect (such as that of March of the Machines) will make those artifact Auras into creatures. An Aura that's also a creature can't enchant anything. It's unattached the next time state-based actions are checked, and then immediately put into its owner's graveyard as a second state-based action.

Nonland permanents you control are artifacts in addition to their other types. The same is true for permanent spells you control and nonland permanent cards you own that aren't on the battlefield.

Evolved Spinoderm

If Evolved Spinoderm somehow loses all of its oil counters due to an effect other than its upkeep triggered ability, this won't cause its controller to sacrifice it until the next time its upkeep triggered ability resolves.

Evolved Spinoderm enters with four oil counters on it.
Evolved Spinoderm has trample as long as it has two or fewer oil counters on it. Otherwise, it has hexproof.
At the beginning of your upkeep, remove an oil counter from Evolved Spinoderm. Then if it has no oil counters on it, sacrifice it.

"Ah, my old friends. Have you decided at last to stop clinging to the past and join me in the grand pursuit of perfection?"

Ezuri, Stalker of Spheres

If you proliferate twice, you don't have to choose the same set of players and/or permanents to get additional counters each time.

While proliferating twice, players can't respond between proliferating the first time and proliferating the second time.

When Ezuri, Stalker of Spheres enters, you may pay {3}. If you do, proliferate twice.
Whenever you proliferate, draw a card.

"It seems someone forgot to read the fine print."

Geth, Thane of Contracts

Other creatures you control get -1/-1.
{1}{B}{B}, {T}: Return target creature card from your graveyard to the battlefield. It gains "If this creature would leave the battlefield, exile it instead of putting it anywhere else." Activate only as a sorcery.

Glissa Sunslayer

For the third mode, you choose which counters to remove as the ability resolves. You may remove any three (or fewer) counters, even if the permanent has multiple kinds of counters on it.

First strike, deathtouch
Whenever Glissa Sunslayer deals combat damage to a player, choose one —
• You draw a card and you lose 1 life.
• Destroy target enchantment.
• Remove up to three counters from target permanent.

Graaz, Unstoppable Juggernaut

If Graaz loses its abilities for some reason, then Juggernauts you control will not have to attack each combat and will be able to be blocked by Walls. However, due to how continuous effects are applied in layers, other creatures you control will continue to be 5/3 Juggernauts in addition to their other types. Unstoppable, indeed!

Juggernauts you control attack each combat if able.
Juggernauts you control can't be blocked by Walls.
Other creatures you control have base power and toughness 5/3 and are Juggernauts in addition to their other creature types.

Green Sun's Twilight

If X is 5 or more, you choose whether to put both cards into your hand or both cards onto the battlefield. You can't choose to put one into your hand and the other onto the battlefield.

Reveal the top X plus one cards of your library. Choose a creature card and/or a land card from among them. Put those cards into your hand and the rest on the bottom of your library in a random order. If X is 5 or more, instead put the chosen cards onto the battlefield or into your hand and the rest on the bottom of your library in a random order.

Ichormoon Gauntlet

Only one loyalty ability of each planeswalker may be activated per turn, no matter how many it has gained.

Planeswalkers you control have "[0]: Proliferate" and "[−12]: Take an extra turn after this one."
Whenever you cast a noncreature spell, choose a counter on target permanent. Put an additional counter of that kind on that permanent.

Jace, the Perfected Mind

A Phyrexian mana symbol contributes 1 toward the mana value of a card, even if life is paid for it. Specifically, Jace's mana value is always 4.

Jace's second loyalty ability doesn't care which player's graveyard has twenty or more cards in it. It could be the target player's or another player's.

Other replacement effects that would change the number of loyalty counters Jace enters with will apply as normal.

The compleated ability looks only at whether a player chose to pay 2 life for a Phyrexian mana symbol as they were casting the spell. If a player paid life for some other reason while casting the spell, that will not reduce the number of loyalty counters the planeswalker enters the battlefield with.

Compleated ({U/P} can be paid with {U} or 2 life. If life was paid, this planeswalker enters with two fewer loyalty counters.)
[+1]: Until your next turn, up to one target creature gets -3/-0.
[−2]: Target player mills three cards. Then if a graveyard has twenty or more cards in it, you draw three cards. Otherwise, you draw a card.
[−X]: Target player mills three times X cards.

Jor Kadeen, First Goldwarden

The value of X is determined only once, as the triggered ability resolves. If the number of equipped creatures you control changes after that time, it won't change the bonus granted.

Trample
Whenever Jor Kadeen, First Goldwarden attacks, it gets +X/+X until end of turn, where X is the number of equipped creatures you control. Then if Jor Kadeen's power is 4 or greater, draw a card.

Kaito, Dancing Shadow

Even if Kaito's triggered ability triggers more than once in the same turn (perhaps because one or more attackers had first strike, multiple players were dealt combat damage by your creatures, or there were multiple combats), and you return an attacking creature to hand each time, you won't be able to activate Kaito's loyalty abilities more than twice that turn. That is, Kaito's triggered ability is not additive.

If you return a creature to its owner's hand with Kaito's first ability, you may activate a single loyalty ability of Kaito twice, or you may activate two different loyalty abilities.

Whenever one or more creatures you control deal combat damage to a player, you may return one of them to its owner's hand. If you do, you may activate loyalty abilities of Kaito twice this turn rather than only once.
[+1]: Up to one target creature can't attack or block until your next turn.
[0]: Draw a card.
[−2]: Create a 2/2 colorless Drone artifact creature token with deathtouch and "When this creature leaves the battlefield, each opponent loses 2 life and you gain 2 life."

Karumonix, the Rat King

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
Other Rats you control have toxic 1.
When Karumonix enters, look at the top five cards of your library. You may reveal any number of Rat cards from among them and put the revealed cards into your hand. Put the rest on the bottom of your library in a random order.

Kaya, Intangible Slayer

Any enters-the-battlefield abilities of the copied permanent will trigger when the token enters the battlefield. Any "as [this permanent] enters the battlefield" or "[this permanent] enters the battlefield with" abilities of the chosen permanent will also work.

Except for the listed exceptions, the token copies exactly what was printed on the original permanent and nothing else (unless that permanent is copying something else or it is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, and so on.

For the middle loyalty ability, each opponent in turn order chooses whether or not to scry. Those who do (likely all of them) look at the top card of their library at the same time, then they decide in turn order where their card goes. Each opponent will know the choices of previous players in turn order before making their own choices.

If the copied creature has {X} in its mana cost, X is 0.

If the copied creature is a token, the new token that's created copies the original characteristics of that token as stated by the effect that created that token, with the exceptions noted above.

If the copied permanent is copying something else, then the token enters the battlefield as whatever that permanent copied, with the exceptions noted above.

Kaya's last ability checks to see whether the permanent was an Aura when it last existed on the battlefield, not whether it is an Aura card in exile. For example, if an enchantment creature with the bestow ability (an ability that allows a creature card to be cast as an Aura instead) is an Aura and the target of Kaya's last ability, the ability will not create a copy of it.

Hexproof
[+2]: Each opponent loses 3 life and you gain 3 life.
[0]: You draw two cards. Then each opponent may scry 1.
[−3]: Exile target creature or enchantment. If it wasn't an Aura, create a token that's a copy of it, except it's a 1/1 white Spirit creature with flying in addition to its other types.

Kemba, Kha Enduring

Whenever Kemba, Kha Enduring or another Cat you control enters, attach up to one target Equipment you control to that creature.
Equipped creatures you control get +1/+1.
{3}{W}{W}: Create a 2/2 white Cat creature token.

Kethek, Crucible Goliath

If a creature on the battlefield has an {X} in its mana cost, X is 0.

At the beginning of your end step, you may sacrifice another creature. If you do, reveal cards from the top of your library until you reveal a nonlegendary creature card with lesser mana value, put it onto the battlefield, then put the rest on the bottom of your library in a random order.

Koth, Fire of Resistance

Koth's emblem is colorless. Notably, this means that protection from red won't stop a permanent or player from being the target of the emblem's ability, nor will it prevent the damage being dealt. Replacement effects that care about damage from a red source don't apply to it.

[+2]: Search your library for a basic Mountain card, reveal it, put it into your hand, then shuffle.
[−3]: Koth, Fire of Resistance deals damage to target creature equal to the number of Mountains you control.
[−7]: You get an emblem with "Whenever a Mountain you control enters, this emblem deals 4 damage to any target."

Lukka, Bound to Ruin

A hybrid Phyrexian mana symbol contributes 1 toward the mana value of a card, even if life is paid for it. Specifically, Lukka's mana value is always 5.

For Lukka's last ability, you announce the targets and how damage is divided as you activate the ability. Once the ability has been activated, the greatest power among creatures you control no longer matters for this ability. This means once you announce you're activating it, no player can respond to try and lower that power and decrease the damage Lukka can deal.

If some of the targets of the last ability become illegal, the original division of damage still applies, but the damage that would have been dealt to illegal targets isn't dealt at all.

Other replacement effects that would change the number of loyalty counters Lukka enters with will apply as normal.

You can't choose more targets than the greatest power among creatures you control as you activate the ability, and each chosen target must receive at least 1 damage.

Compleated ({R/G/P} can be paid with {R}, {G}, or 2 life. If life was paid, this planeswalker enters with two fewer loyalty counters.)
[+1]: Add {R}{G}. Spend this mana only to cast creature spells or activate abilities of creatures.
[−1]: Create a 3/3 green Phyrexian Beast creature token with toxic 1.
[−4]: Lukka deals X damage divided as you choose among any number of target creatures and/or planeswalkers, where X is the greatest power among creatures you control as you activate this ability.

Malcator, Purity Overseer

Malcator will count any artifacts that entered the battlefield under your control during the turn, even if you didn't control Malcator at the time. Malcator won't count non-artifact permanents you controlled that became artifacts.

When Malcator, Purity Overseer enters, create a 3/3 colorless Phyrexian Golem artifact creature token.
At the beginning of your end step, if three or more artifacts entered the battlefield under your control this turn, create a 3/3 colorless Phyrexian Golem artifact creature token.

Melira, the Living Cure

Melira's first ability creates a replacement effect. If another replacement effect would also change the number of poison counters a player receives, such as that of Vorinclex, Monstrous Raider, the player receiving the counters chooses which one to apply first, regardless of who controls what permanents. This will usually result in that player choosing to apply Melira's effect last and receive one counter. However, if they want to, they could apply Melira's replacement effect first and receive more counters.

Once Melira's replacement effect has been applied in a turn, additional events that would put poison counters on a player don't happen, regardless of any other replacement effects involved.

If you would get one or more poison counters, instead you get one poison counter and you can't get additional poison counters this turn.
Exile Melira, the Living Cure: Choose another target creature or artifact. When it's put into a graveyard this turn, return that card to the battlefield under its owner's control.

Mercurial Spelldancer

A copy is created even if the spell that caused the delayed triggered ability to trigger has been countered by the time that delayed triggered ability resolves. The copy resolves before the original spell.

Any choices made when the spell resolves won't have been made yet when it's copied. Any such choices will be made separately when the copy resolves.

If the spell has damage divided as it was put onto the stack, the division can't be changed, although the targets receiving that damage still can. The same is true of spells that distribute counters.

If the spell that's copied has an X whose value was determined as it was cast, 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 or modes. You can't choose different ones.

The copy is created on the stack, so it's not "cast." Creating the copy won't cause abilities that trigger when a player casts a spell to trigger.

The copy will have the same targets as the spell it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If the spell is a permanent spell with targets, such as an Aura, you may also choose a new target for that spell. The new targets must be legal. If, for any target, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).

You can't choose to pay any additional costs for a copied spell. 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.

Mercurial Spelldancer can't be blocked.
Whenever you cast a noncreature spell, put an oil counter on Mercurial Spelldancer.
Whenever Mercurial Spelldancer deals combat damage to a player, you may remove two oil counters from it. If you do, when you next cast an instant or sorcery spell this turn, copy that spell. You may choose new targets for the copy.

Migloz, Maze Crusher

Migloz, Maze Crusher enters with five oil counters on it.
{1}, Remove an oil counter from Migloz: It gains vigilance and menace until end of turn.
{2}, Remove two oil counters from Migloz: It gets +2/+2 until end of turn.
{3}, Remove three oil counters from Migloz: Destroy target artifact or enchantment.

Mindsplice Apparatus

Flash
At the beginning of your upkeep, put an oil counter on Mindsplice Apparatus.
Instant and sorcery spells you cast cost {1} less to cast for each oil counter on Mindsplice Apparatus.

"Melira helped me design it. Those who are infected by the oil cannot cross the threshold. We should be safe inside."

Mirran Safehouse

Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keywords are activated abilities; they have colons in their reminder text.

Cards with basic land types intrinsically have the appropriate mana ability, even if it isn't printed in the card's text box. Mirran Safehouse also gains those abilities. For example, if there is a Plains in your graveyard, Mirran Safehouse has "{T}: Add {W}," even though that may not be printed on the Plains itself.

If an activated ability of a land card in a graveyard references the card it's printed on by name, treat Mirran Safehouse's version of that ability as though it referenced Mirran Safehouse by name instead.

Mirran Safehouse gains only activated abilities, including activated mana abilites. It doesn't gain keyword abilities (unless those keyword abilities are activated), triggered abilities, or static abilities.

As long as Mirran Safehouse is on the battlefield, it has all activated abilities of all land cards in all graveyards.

Mirrex

{T}: Add {C}.
{T}: Add one mana of any color. Activate only if Mirrex entered this turn.
{3}, {T}: Create a 1/1 colorless Phyrexian Mite artifact creature token with toxic 1 and "This creature can't block." (Players dealt combat damage by it also get a poison counter.)
