Creature — Spirit
Flying, double strike, lifelink Whenever you gain life, draw a card.
Metagame: appears in 1 deck (2.9 %)
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.
If Drogskol Reaver deals enough first-strike damage to destroy each creature it’s blocking or was blocked by, it won’t deal any damage during the regular combat damage step (unless it’s attacking and somehow gains trample). Its ability won’t trigger a second time that combat.
