A warrior I was playing tonight was able to get their armor much higher than I would have liked. In Hearthstone a hero's armor is similar to a hero's healtharmor is similar to a hero's health and since there is no practical limit to the amount of armor a hero can stackno practical limit to the amount of armor a hero can stack, his armor advantage became insurmountable.
While I was being summarily beaten I found myself wondering if there was a card that had any affect on a hero's armor. Essentially something like the Acidic Swamp Ooze, but with an effect on armor instead of a hero's weapon. Is there an armor countering card in Hearthstone? If no such card exists what is an effective strategy to control a run away armor train?
