in the Puzzle Lab, I cannot beat the first Crystalsmith Kangor puzzle. (survival, the 4th boss, 1st puzzle). The card that is supposed to make my cards cost heath instead of mana does not seem to impact the Lord Jaraxxus card. It does not matter if Jaraxxus is still on enemy board, in my deck, or in my hand when i play the card, I simply cannot play Lord Jaraxxus. I suppose this puzzle must be broken.
