How do you counter zir’an healyonar? I don’t see a way to do it unless playing healyonar as well, a minion doesn 't even need to be wounded for their abilities to proc, and many times it’s just “if anything is healed.” The only counter I can see is to play healyonar as well to take the benefits and hope you have a better deck than the other, but what about the other factions and deck archetypes?
Of course, the most obvious answer (answer to everything): carry a shit-ton of dispels and shit-ton of hard removal. That’s not really an answer, since most heals are spells or instant cast, and again: the creature doesn’t even need to be wounded.
CPG really need to differentiate between “a minion/general is healed” and “healing is cast.”
