A value card, but slow. You'll need to use a Whirlwind effect or the new 1/3 the turn it's summoned to get use out of it, or it'll just get killed instantly. I'm actually not sure it'll find a place in the new Control Warrior. I'm guessing not, but it's possible.
Pretty sweet. Even killing it without Polymorph style removal kills nets at least one Legendary, maybe two. That plus Whirlwind or some other form of Pinging it on the turn it comes in nets you 2-3 legends, minimum. In Taunt Warrior, where it is protected? Even better.
