I feel like if you playing this you are already dead...
Good for those earlier, smaller minions on your opponent's side. And this card gets is highest value with other Armor synergy we've been seeing for this expansion and past expansions that rely on amount of armor you have
this gains you +2 armor for every enemy minion. and then u do dmg eaqual to your armor to all minions. and this combo costs 5 mana. if u do this against 2 enemy minions that already a flame strike. not rearding any armor u might have from previous turns.
I don't think it's all that good. You'd rather play a taunt like Tar Creeper if you desperately need to stay alive. If you play this against a single minion on curve, it's like a marginal better Gadgetzan Socialite. It does have appeal if you combo it with a board clear, just as a means to gain armor, since it's cheap to play.
this is good because it combos with other cards that wev'e seen in this set, especially with reckless flurry. this is also good with shield slam and this can actually buy you another turn against zoo decks.
