55 attack for 50 resources. Both players lose 10 stock. That's not a rare burning. it has a great cost (dragons can be played at this cost and they might even deal higher damage). The stock reduction for both players is a great loss, and the way I realize the game, rares are supposed to provide an immense effect compared to the resources they are costing. (i.e. each resource deals about 2-3 damage). In my oppinion this should have a cost reduction, or at least remove the stock loss for the player who plays it. Perhaps replace stock loss with flare attack?
