Whenever you gain life, draw a card.
i never played this card but i dont never really understood it as far as standard playablity goes.
I never played this guy outside of cube draft. It was standard playable?
If multiple creatures with lifelink you control deal combat damage at the same time, the damage dealt by each of those creatures is a separate life-gaining event and Drogskol Reaver's ability will trigger that many times.
