Revengevine

Trample, Haste, Reincarnate (When this creature dies, exile cards from the top of your library until you reveal a creature with equal or lesser mana value. You may put it onto the battlefield tapped. Put the exiled cards onto the bottom of your library in a random order.)

Whenever two or more creatures you control die, if Revengevine is in your graveyard, you may return it to your hand.
