Yvruul, Void Manifest

Yvruul can’t attack unless the total mana value of permanents you control is 27 or greater.
Annihilator 3
If a source you control would cause a permanent to enter the graveyard or be exiled, exile it with a void counter instead.
Whenever an instant or sorcery spell is cast, transform Yvruul. If that spell targets Yvruul, counter and exile it with a void counter.
