Valgavoth, Terror Eater

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.
