Hearthstone

I think it's the least viable class in arena, because you can't use the hero power even when you have two mana left: if you had a good choice for the cards, you normally have cards to draw already, and killing yourself's hp can't work in arena. It's ok in ranked cuz you are either aggro, or handlock, so the loss of health either doesn't matter, or is even good (molten giant).

I hate crafting common too, how much dust do you have?
