Anub'arak, Traitor King

(Proxy for Kathril, Aspect Warper.)
Whenever Anub'arak, Traitor King enters the battlefield, put a flying counter on any creature you control if a creature card in your graveyard has flying. Repeat this process for first strike, double strike, deathtouch, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance.
Then put a +1/+1 counter on Anub'arak, Traitor King for each counter put on a creature this way.
