La'raa, Emissary of Revival

Reach, Vigilance

Whenever a creature you cast enters, put a +1/+1 counter on it. If a creature you control with a +1/+1 counter on it would attack, draw a card.

When a creature you control dies, remove all +1/+1 counters from it and you gain life equal to that many +1/+1 counters on it. Then put a creature from your graveyard onto the battlefield that has not died this turn.
