Criatura — Anão Mago
1 / 3
Salvaguarda — Pague 2 pontos de vida. (Toda vez que esta criatura se tornar alvo de uma mágica ou habilidade que um oponente controla, anule-a, a menos que aquele jogador pague 2 pontos de vida.)
Destreza (Toda vez que você conjura uma mágica não de criatura, esta criatura recebe +1/+1 até o final do turno.)
Once it triggers, prowess isn't connected to the spell that caused it to trigger. If that spell is countered, prowess will still resolve.
Prowess goes on the stack on top of the spell that caused it to trigger. It will resolve before that spell.
Any spell you cast that doesn't have the type creature will cause prowess to trigger. If a spell has multiple types, and one of those types is creature (such as an artifact creature), casting it won't cause prowess to trigger. Playing a land also won't cause prowess to trigger.
