Got to love the flavor of the card, of course it's bad it's called Lackey, it lackeys any impact or value. They really nailed the fantasy of this one. If you want to build a Lackey deck this is your bro.
Wtf? There aren't enough high-costing demons to warrant this card. Even then, it's only a deathrattle and loses you tempo. You'd have to play a deck that only plays 5+ cost stuff to be even remotely worth it, and even then you'd rather play it straight up by yourself.
