Seems like dual Shield Slam packed in one card. The drawback is ofc taking damage but at least this cannot be geisted. If they wanted to make an agreeable type of Fiery Win Axe, i really like their concept.
Wow, i teorycrafted about control warrior for K&C, and there was 11-12 two-mana cards in deck. So now it should be 13-14? Omg))
However I doubt it will be so playable. CW needs stable early game removal, like bash or 2 mana 3 damage weapon. This one requires to spend mana on armor gain and then loose this armor on attack, and for CW it is better to attack first and loose health, and then play armor for sh:slams or aoe removal.
Maybe with that 3 mana minion which gives you immunity on attack? Dunno, for the late game gorehawl with that minion seems better
I have little doubt this will be good in wild with justicar. In standard I don't think there are enough armor gain cards that do enough besides gaining armor. You can't win just by gaining armor after all.
It's not rare for a warrior to have tons of armour after 8 turns. Being able to kill a big minion for only two mana while using some of that armour may swing the game it's way. And just waiting a few turns for that weapon to do it again is quite likely. I would say very good.
I dont think this card can see play. If you attacking into big things with this weapon you're going to keep having to gain 4-5 armor each time you attack. your hero power only gives 2 armor and 2m 2/2 weapon is pretty mediocre in a control deck.
