El propietario de la criatura objetivo la pone en la parte superior o en el fondo de su biblioteca. Creas una ficha de criatura Zombie negra 2/2 con la habilidad de descomposición. (No puede bloquear. Cuando ataque, sacrifícala al final del combate.)
Decayed does not create any attacking requirements. You may choose not to attack with a creature that has decayed.
Once a creature with decayed attacks, it will be sacrificed at end of combat, even if it no longer has decayed at that time.
Decayed represents a static ability and a triggered ability. "Decayed" means "This creature can't block" and "When this creature attacks, sacrifice it at end of combat."
Decayed does not grant haste. Creatures with decayed that enter the battlefield during your turn may not attack until your next turn.
