There is some really grate Cthulhu and Cthulhu-esque artwork out there. I'll try and dig some up later. It's been too long since I've played MTG to really have any idea about the stats. Maybe tap it to drive target creature to madness or something and it becomes under your control for your next attack turn. Or 'sacrifice' a creature you control to the elder gods to deal X damage where X is the sacrificed creature's toughness. Something like that. It's been too long for me to have enough a grasp of the game to be helpful there.
