Encantamento - Aura
Encantar Criatura
A criatura encantada tem "No final de seu turno, sacrifique esta criatura, a menos que ela tenha atacado neste turno."
Instill Furor grants a triggered ability that triggers at the end of the creature’s controller’s turn.
Once the ability triggers, nothing that happens to Instill Furor can prevent the ability from resolving.
