Kierkegaard, Deranged Priest

Sacrifice an artifact: Add {c}{c}.
Whenever you sacrifice an artifact, if it's the third artifact you control that's been put into the
graveyard this way this turn, you pay pay life
equal to target creature's converted mana cost in
your graveyard. If you do, return that creature to
the battlefield tapped.
