After I played a bit with this exact deck, it's pretty strong. BUT, I also can conclude some things.
This is very "sensible" : if you don't draw a mix of armor regain and strong minion / weapon response in the course of any game, you're screwed either by aggro heavy decks (they are plenty currently : mech mage, hunter, zoo lock...) IF they draw "quite well" by having not enough armor / life OR by fatigue decks by having too much armor and not enough face damage to oponent.
In fact, it's likely you'll have to fight your way to the ladder a lonnnng time playing with statistics even if you're playing well. It's not rare that I don't draw Alexstraza's before dying, any armor up (maiden etc.) before dying, armorsmith or weapon before turn 10 ! (lol) ... It's quite embarassing sometimes.
