That is an absolutely terrifying card with Missile Launcher. 6-mana to get a pulsing board clear just murders zoo decks. Hunter has never had a wide board clear similar to equali-crate and this combo is even better than that one.
Wow, that's a card that makes Missile Launcher super powerful. Unless your opponent has a silence or removal, he will be phased out of the game. I'd say it might not be consistent enough to actually see high-ranked play but it will surely be rage-inducing against newbies who can't play any minions because they are immediately killed next turn. It's just a bad design because it's going to be most potent against newcomers that don't know how to build a proper deck yet and that may scare them away.
