Not overly impressed with Razaketh, the Foulblooded. BBB(5) 8/8 flying trample with Pay 2 Life: Sacrifice another Creature. Search for a creature and put it in your hand.
Seems really expensive. Yes, it'll end games if left alone, but at 8 mana, it should. It has no protection from removal and, while the tutoring is nice, it's not earthshaking. I was hoping for more out of this guy.
