Valgavoth, Terror Eater (DSK #352)

Flying, lifelink

Ward—Sacrifice three nonland permanents.

If a card you didn’t control would be put into an opponent’s graveyard from anywhere, exile it instead.

During your turn, you may play cards exiled with Valgavoth. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.
