Oblivion, Black Pact

Menace, Lifelink

You cannot gain life. Whenever you would gain life, you deal damage equal to the life you would've gained to a target opponent.

Whenever Oblivion, Black Pact attacks, create a 3/3 black Wurm creature token with lifelink that's tapped and attacking.
Creature tokens get -1/-1 at the end of their controller's turn.
