Encantamento — Aura
Encantar criatura
Toda vez que a criatura encantada atacar, coloque um marcador +1/+1 nela. Depois, se ela tiver três ou mais marcadores +1/+1, sacrifique Provação de Heliode.
Quando você sacrifica Provação de Heliode, você ganha 10 pontos de vida.
If you sacrifice the Ordeal in some other way, its last ability will trigger.
The +1/+1 counter is put on the creature before blockers are declared and before combat damage is dealt.
The check of whether the enchanted creature has three or more +1/+1 counters on it happens as part of the resolution of the attack triggered ability. If the third +1/+1 counter is put on the enchanted creature any other way, you won't sacrifice the Ordeal until the next time the creature attacks.
