Denrik Stoutheart

Defender, tenacity 2 (Whenever this creature becomes the target of a spell or ability an opponent controls, it gets +2/+2 until end of turn.)
As long as an opponent's life total is equal to or greater than your own, Denrik Stoutheart can attack as though it didn't have defender and has first strike and inexorable. (This creature has hexproof as long as it is attacking.)
