rated as bad. Seems weak stats for 8 mana. Almost need to pair it with Baneful Banker , Cornered Sentry or Gravelsnout Knight to ensure some value from it by giving you another one or a guaranteed kill at turn 9+
This is actually pretty awesome IMO, if any form of control warrior can make it to tier 2+ (personally I've had success on ladder with a control shell that includes the rush package, plus Dr Boom and Omega Assembly, as well as Dead Man's Hand to break the control deadlock). If we consider a 5/5 buff on a minion to be worth about 3-4 mana (by Blessing of Kings standard it's worth 5, but people don't play cards just because they're 'fair'), then we're looking at a ~4/5 rush for 5 (technically 5/5 but as you badly want to Overkill it realistically is only doing 4 damage worth) that draws you another rush card + the imaginary buff card.
Not to mention, the rush package (the 3 mana Worgen, 4 mana temporary 5/5 and Crowley) can struggle against bigger threats, and the buff definitely helps there - even if it hits the Worgen that's an 8/8 rusher. Hit Crowley, and he can hit something big to start growing, as opposed to having to start with a something much smaller.
Stats are too low imo. You need to kill something with 4 HP to get the effect to go off, and by turn 8 if you're playing against Control, then that's hard to do and against Aggro this card is hardly something you'll be able to do that late in the game.
The straw that breaks the camel's back. Will see constructed play, the archtype will develop around this, Oondasta, and Darius. They want Warrior to be able to clear big boards with minions, this does exactly that, it's why the Goons failed so hard, it had no attatchment to the board, just piles of stats.
im going to say really good 4/5 with rush that draws you a rush minion with a 5/5 boost bet this will see some testing in deadman's hand decks in wild if this goes off once thats infinite* looping 8 mana 10/10 rush beast
