Adaptive Sporesinger

Vigilance
When Adaptive Sporesinger enters the battlefield, choose one —
• Target creature gets +2/+2 and gains vigilance until end of turn.
• Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

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

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.

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.

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.

Vigilance
When Adaptive Sporesinger enters, choose one —
• Target creature gets +2/+2 and gains vigilance until end of turn.
• Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

Adriana, Captain of the Guard

Melee (Whenever this creature attacks, it gets +1/+1 until end of turn for each opponent you attacked this combat.)
Other creatures you control have melee. (If a creature has multiple instances of melee, each triggers separately.)

Creatures that enter the battlefield attacking were never declared as attackers, so they won't count toward melee's effect. Similarly, if a creature with melee enters the battlefield attacking, melee won't trigger.

It doesn't matter how many creatures you attacked a player with, only that you attacked a player with at least one creature. For example, if you attack one player with Wings of the Guard and another player with five creatures, Wings of the Guard will get +2/+2 until end of turn.

Melee will trigger if the creature with melee attacks a planeswalker. However, the effect counts only opponents (and not planeswalkers) that you attacked with a creature when determining the bonus.

You determine the size of the bonus as the melee ability resolves. Count each opponent that you attacked with one or more creatures. It doesn't matter if the attacking creatures are still attacking or even if they are still on the battlefield. It also doesn't matter if the opponent you attacked is still in the game.

Against All Odds

Choose one or both —
• Exile target artifact or creature you control, then return it to the battlefield under its owner's control.
• Return target artifact or creature card with mana value 3 or less from your graveyard to the battlefield.

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

All Will Be One

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.

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.

The Mirran forces thought they'd vanquished their foes . . . until a nearby monument got up and started stalking toward them.

Ambulatory Edifice

When Ambulatory Edifice enters the battlefield, you may pay 2 life. When you do, target creature gets -1/-1 until end of turn.

You don't choose a target for Ambulatory Edifice's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you pay 2 life 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.

When Ambulatory Edifice enters, you may pay 2 life. When you do, target creature gets -1/-1 until end of turn.

There's never a need to change the watch, for the servants of Norn are sleepless.

Annex Sentry

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
When Annex Sentry enters the battlefield, exile target artifact or creature an opponent controls with mana value 3 or less until Annex Sentry leaves the battlefield.

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.

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.

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.

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.

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
When Annex Sentry enters, exile target artifact or creature an opponent controls with mana value 3 or less until Annex Sentry leaves the battlefield.

By gaze, sting, and claw, Vraska will see the will of Phyrexia done.

Annihilating Glare

As an additional cost to cast this spell, pay {4} or sacrifice an artifact or creature.
Destroy target creature or planeswalker.

Many vatkeepers use necrogen etchings to judge the value of their aspirants. If the wounds rot and fester, the recipient is not worth further effort.

Anoint with Affliction

Exile target creature if it has mana value 3 or less.
Corrupted — Exile that creature instead if its controller has three or more poison counters.

As Anoint with Affliction resolves, if the creature's controller has three or more poison counters, the creature will be exiled no matter what its mana value is. If the controller doesn't, the creature will be exiled only if its mana value is 3 or less.

You may choose to target a creature that has mana value greater than 3 even if no player has three of more poison counters.

"Be not afraid of the holy chorus. Join in rapturous harmony."

Apostle of Invasion

Flying
Corrupted — As long as an opponent has three or more poison counters, Apostle of Invasion has double strike.

In a multiplayer game, Apostle of Invasion can lose double strike after dealing damage in the first combat damage step if all the opponents that had three or more poison counters left the game. (This is most likely due to that combat damage, so good job!). In that case, it will not deal any combat damage in the regular combat damage step.

It started as a mere drop of water. The Magic Mirror crystallized it into much more.

Arcane Signet

{T}: Add one mana of any color in your commander's color identity.

If you don't have a commander, Arcane Signet's ability produces no mana.

If you have two commanders, the ability adds one mana of any color in their combined color identities.

If your commander is a card that has no colors in its color identity, Arcane Signet's ability produces no mana. It doesn't produce {C}.

Archfiend of the Dross

Flying
Archfiend of the Dross enters the battlefield 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.

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

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.

Arek, False Goldwarden

Starting intensity 0
Whenever another creature enters under your control, cards you own named Arek, False Goldwarden intensify by 1.
{3}{W}{B}, {T}, Sacrifice Arek, False Goldwarden: Target opponent loses X life and you gain X life, where X is Arek's intensity.

Argentum Masticore

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.

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.

Armored Scrapgorger

Armored Scrapgorger gets +3/+0 as long as it has three or more oil counters on it.
{T}: Add one mana of any color.
Whenever Armored Scrapgorger becomes tapped, exile target card from a graveyard and put an oil counter on Armored Scrapgorger.

Armored Scrapgorger's last ability triggers whenever it becomes tapped for any reason, not just due to its mana ability.

If the card chosen as the target of the last ability is an illegal target as the ability tries to resolve, most likely because it left the graveyard some other way, the ability will fail to resolve and none of its effects will happen. Armored Scrapgorger won't get an oil counter.

For the aspirants of the Progress Engine, being launched into the sphere's upper reaches is a great honor. Some are even granted wings beforehand.

Aspirant's Ascent

Until end of turn, target creature gets +1/+3 and gains flying and toxic 1. (Players dealt combat damage by that creature also get a poison counter.)

Giving an attacking creature flying after it has become blocked will not cause it to become unblocked, even if the blocking creature can't normally block creatures with flying.

Assemble the Legion

At the beginning of your upkeep, put a muster counter on Assemble the Legion. Then create a 1/1 red and white Soldier creature token with haste for each muster counter on Assemble the Legion.

If Assemble the Legion isn't on the battlefield when its ability resolves, use the number of muster counters it had when it was last on the battlefield to determine how many Soldier tokens to create.

It is Jin-Gitaxias's deepest exasperation that any part of his domain still requires maintenance.

Atmosphere Surgeon

Whenever you cast a noncreature spell, put an oil counter on Atmosphere Surgeon.
Remove an oil counter from Atmosphere Surgeon: Target creature gains flying until end of turn. Activate only as a sorcery.

Atraxa's Skitterfang

Atraxa's Skitterfang enters the battlefield with three oil counters on it.
At the beginning of combat on your turn, you may remove an oil counter from Atraxa's Skitterfang. When you do, target creature you control gains your choice of flying, vigilance, deathtouch, or lifelink until end of turn.

You choose which ability the target creature gets as the reflexive ability resolves. Players may not wait to see what ability you choose before deciding whether to respond to it.

You don't choose a target for Atraxa's Skitterfang's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you remove an oil counter 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.

Atraxa's Skitterfang enters with three oil counters on it.
At the beginning of combat on your turn, you may remove an oil counter from Atraxa's Skitterfang. When you do, target creature you control gains your choice of flying, vigilance, deathtouch, or lifelink until end of turn.

Atraxa, Grand Unifier

Flying, vigilance, deathtouch, lifelink
When Atraxa, Grand Unifier enters the battlefield, 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.)

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.

Awaken the Sleeper

Gain control of target creature until end of turn. Untap that creature. It gains haste until end of turn. If it's equipped, you may destroy all Equipment attached to that creature.

"I will not rest until the truth of Phyrexia is inscribed across the Multiverse."

Axiom Engraver

Axiom Engraver enters the battlefield with two oil counters on it.

Barbed Batterfist

For Mirrodin (When this Equipment enters the battlefield, create a 2/2 red Rebel creature token, then attach this to it.)
Equipped creature gets +1/-1.
Equip {1} ({1}: Attach to target creature you control. Equip only as a sorcery.)

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.

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.

For Mirrodin! (When this Equipment enters, create a 2/2 red Rebel creature token, then attach this to it.)
Equipped creature gets +1/-1.
Equip {1} ({1}: Attach to target creature you control. Equip only as a sorcery.)

Basilica Shepherd

Flying
When Basilica Shepherd enters the battlefield, create two 1/1 colorless Phyrexian Mite artifact creature tokens with toxic 1 and "This creature can't block." (Players dealt combat damage by them also get a poison counter.)

It shines with the conviction of a zealous acolyte.

Basilica Skullbomb

{1}, Sacrifice Basilica Skullbomb: Draw a card.
{2}{W}, Sacrifice Basilica Skullbomb: Target creature you control gets +2/+2 and gains flying until end of turn. Draw a card. Activate only as a sorcery.

If the target of Basilica Skullbomb's last ability isn't a legal target as the ability tries to resolve (probably because it has left the battlefield), you won't draw a card.

Battle Screech

Create two 1/1 white Bird creature tokens with flying.
Flashback—
Tap three untapped white creatures you control. (You may cast this card from your graveyard for its flashback cost. Then exile it.)

A spell cast using flashback will always be exiled afterward, whether it resolves, is countered, or leaves the stack in some other way.

If a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.

To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.

You can cast a spell using flashback even if it was somehow put into your graveyard without having been cast.

You must still follow any timing restrictions and permissions, including those based on the card's type. For instance, you can cast a sorcery using flashback only when you could normally cast a sorcery.

“Flashback [cost]” means “You may cast this card from your graveyard by paying [cost] rather than paying its mana cost” and “If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack.”

You can tap any untapped white creatures you control to pay for Battle Screech’s flashback cost, even ones you haven’t controlled continuously since the beginning of your most recent turn.

Create two 1/1 white Bird creature tokens with flying.
Flashback—Tap three untapped white creatures you control. (You may cast this card from your graveyard for its flashback cost. Then exile it.)

"Kill the weak so they can't drag the strong down to their level. This is true compassion."
—Benzir, archdruid of Temple Might

Beast Within

Destroy target permanent. Its controller creates a 3/3 green Beast creature token.

If the permanent is still a legal target but is not destroyed (perhaps because it regenerated or has indestructible), its controller still gets the Beast token.

If the target permanent is an illegal target by the time Beast Within tries to resolve, the spell won't resolve. No player creates a Beast token. If the target is legal but not destroyed (most likely because it has indestructible), its controller does create a Beast token.

"Watch your footing around here. Anything you might step on probably has teeth."

Bilious Skulldweller

Deathtouch
Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)

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

Black Sun's Twilight

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.

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.

Where ambition meets industry, passion is poisoned by greed.

Blackcleave Cliffs

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

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

For Mirrodin (When this Equipment enters the battlefield, 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}

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 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}

For Mirrodin
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}

"Let those thanebound dissenters prattle about their dead god. I serve the Mother of Machines, and in her name I carve out their heresy."

Bladegraft Aspirant

Menace
Equipment spells you cast cost {1} less to cast.
Activated abilities of Equipment you control that target Bladegraft Aspirant cost {1} less to activate.

Bladehold Cleaver

For Mirrodin!
Equipped creature gets +2/+2.
Whenever equipped creature dies, draft a card from Bladehold Cleaver's spellbook.
Equip {3}

Bladehold War-Whip

For Mirrodin (When this Equipment enters the battlefield, create a 2/2 red Rebel creature token, then attach this to it.)
Equip abilities you activate of other Equipment cost {1} less to activate.
Equipped creature has double strike.
Equip {3}{R}{W}

Bladehold War-Whip's second ability reduces only the amount of generic mana in equip abilities. For example, it will reduce an equip cost of {1} to {0}, but it will have no effect on an equip cost of {G}.

Some Equipment creature cards in other sets have reconfigure, a different ability that attaches them to a creature. Reconfigure is not an equip ability, and reconfigure costs are not reduced by Bladehold War-Whip's second ability.

The second ability affects other Equipment even if it isn't currently attached to a creature.

For Mirrodin! (When this Equipment enters, create a 2/2 red Rebel creature token, then attach this to it.)
Equip abilities you activate of other Equipment cost {1} less to activate.
Equipped creature has double strike.

For Mirrodin
Equip abilities you activate of other Equipment cost {1} less to activate.
Equipped creature has double strike.

"They call themselves the Quiet Furnace? Ironic."

Blazing Crescendo

Target creature gets +3/+1 until end of turn.
Exile the top card of your library. Until the end of your next turn, you may play that card.

If the target creature is an illegal target by the time the spell tries to resolve (most likely because it has left the battlefield in response), the spell will not resolve. No card will be exiled.

You pay all costs and follow all normal timing rules for a card played this way. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty.

Blight Mamba

Infect (This creature deals damage to creatures in the form of -1/-1 counters and to players in the form of poison counters.)
{1}{G}: Regenerate Blight Mamba. (The next time this creature would be destroyed, instead tap it, remove it from combat, and heal all damage on it.)

A player who has ten or more poison counters loses the game. This is a state-based action.

Damage from a source with infect affects planeswalkers normally.

Damage from a source with infect is damage in all respects. If the source with infect also has lifelink, damage dealt by that source also causes its controller to gain that much life. Damage from a source with infect can be prevented or redirected. Abilities that trigger on damage being dealt will trigger if a source with infect deals damage, if appropriate.

If damage from a source with infect that would be dealt to a player is prevented, that player doesn't get poison counters. If damage from a source with infect that would be dealt to a creature is prevented, that creature doesn't get -1/-1 counters.

Infect's effect applies to any damage, not just combat damage.

The -1/-1 counters remain on the creature indefinitely. They're not removed if the creature regenerates or the turn ends.

Infect (This creature deals damage to creatures in the form of -1/-1 counters and to players in the form of poison counters.)
{1}{G}: Regenerate Blight Mamba.

Blightbelly Rat

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
When Blightbelly Rat dies, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

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.)

Blue Sun's Twilight

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.

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.

Bojuka Bog
