Scavenger Seer

Whenever another nontoken creature you control dies, reveal the top card of your library. If it's a land card, put it onto the battlefield. Otherwise put that card into your hand and lose X life, where X is the revealed card's converted mana cost.
Regrow 1: When Scavenger Seer dies, you may sacrifice a creature. If you do, return Scavenger Seer from your graveyard to your hand.
