Lilitu, Weaver of Dark Threads

First strike, lifelink
Whenever another creature dies, you may pay 3
life and exile it. If you do, choose one --
* Put the exiled creature onto the battlefield
under your control at the beginning of your next upkeep. It gains haste. Exile it at end of combat.
* Reveal the top card of your library and put it
into your hand. Each opponent loses life equal to
the exiled creature's power if it's greater than the revealed card's converted mana cost.
