Carnage, karmesinrotes Chaos
4 / 3
Verursacht Trampelschaden
Wenn Carnage ins Spiel kommt, bringe eine Kreaturenkarte deiner Wahl mit Manabetrag 3 oder weniger aus deinem Friedhof ins Spiel zurück. Sie erhält „Diese Kreatur greift in jedem Kampf an, falls möglich" und „Wenn diese Kreatur einem Spieler Kampfschaden zufügt, opfere sie."
Wahnwitz

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