Carnage, Crimson Chaos — ruling 1

Mayhem represents an alternative cost that can be paid to cast a spell from your graveyard if you discarded the card with mayhem that turn. You must pay any additional costs the spell has.

Carnage, Crimson Chaos — ruling 2

You must follow all normal timing rules when casting a spell with mayhem. For example, you can't cast a creature card with mayhem you couldn't normally cast during an opponent's turn, even if you discard that card during an opponent's turn.

Carnage, Crimson Chaos — ruling 3

If a card in a graveyard has {X} in its mana cost, X is 0 when determining its mana value.

Carnage, Crimson Chaos — ruling 4

If the returned creature can't attack for any reason (such as being tapped or having come under your control that turn), then it doesn't attack. If there's a cost associated with having it attack, you're not forced to pay that cost, so it doesn't have to attack in that case either.

Carnage, Crimson Chaos : règles, fonctionnement et interactions (MTG)

Carnage, Crimson Chaos is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Trample When Carnage enters, return target creature card with mana value 3 or less from your graveyard to the battlefield. It gains "This creature attacks each combat if able" and "When this creature deals combat damage to a player, sacrifice it." Mayhem

Complete guide

Carnage, Crimson Chaos is a relentless Symbiote Villain that turns your graveyard into a source of aggressive pressure. By utilizing its unique Mayhem ability, you can bring Carnage back from the brink to lead a charge of reanimated allies. This card excels at maintaining board presence while forcing small, efficient creatures into the fray.

Understanding Mayhem and Reanimation

Carnage, Crimson Chaos features the Mayhem ability, an alternative cost that lets you cast it from your graveyard if you discarded it earlier in the same turn. When it enters the battlefield, you target a creature card in your graveyard with a mana value of 3 or less and return it directly to the battlefield. The reanimated creature is imbued with a bloodlust that forces it to attack every combat if able, and a volatility that causes it to be sacrificed once it successfully deals combat damage to a player.

Step-by-Step Resolution

First, Carnage enters the battlefield, which triggers its reanimation ability. You must choose a legal target in your graveyard with mana value 3 or less at this time. Second, the ability resolves, and the creature enters the battlefield with two new triggered and static abilities. Third, during your next combat, if the creature is able to attack (meaning it is untapped and does not have summoning sickness), it must be declared as an attacker. Finally, if that creature connects with a player, the sacrifice trigger goes on the stack after damage is dealt.

Common Pitfalls

Timing is crucial; you can only use the Mayhem cost if Carnage was discarded that specific turn, and you must still follow normal sorcery-speed timing rules. Furthermore, the 'attacks if able' clause does not override effects like Defender or costs like Propaghanda. If you cannot pay a cost to attack, or if the creature is tapped, it simply doesn't attack. Note that if a creature in your graveyard has {X} in its cost, X is treated as 0 when checking if its mana value is 3 or less.

Strategic Implementation

Carnage is best used with creatures that have powerful 'Enter the Battlefield' or 'Dies' triggers. Since the creature is destined to be sacrificed upon dealing damage, you want to ensure you've gained maximum value before it leaves. Using discard outlets to put Carnage into the graveyard allows you to cast it for its cheaper Mayhem cost, accelerating your game plan and catching opponents off guard with an extra body.

Interaction examples

The Infinite Value Loop

Solemn Simulacrum

If Solemn Simulacrum is in your graveyard, Carnage, Crimson Chaos can return it to the battlefield. You immediately get a land from your library. Because the Simulacrum must attack and will be sacrificed after dealing damage, you are virtually guaranteed to trigger its 'draw a card' ability shortly after, turning Carnage into a powerful engine for both ramp and card draw.

Doubling the Chaos

Roaming Throne

With Roaming Throne on the battlefield naming 'Symbiote' or 'Villain', Carnage's enter-the-battlefield ability triggers twice. This allows you to return two different creatures with mana value 3 or less from your graveyard. Both creatures will gain the requirement to attack and the sacrifice trigger, doubling your aggressive potential in a single turn.
