Nice deck. Sadly, arena AI won't Adrenaline the Brimstone Eaters if you have higher attack creatures in there. Oh well. Just a quick note, too, in case anyone is a dummkopf like me, you shouldn't use both Adrenaline and Mitosis on the same Eater, since Mitosis takes away their
Generate skill. Use each of those on different creatures. Also, I think I might run -1 Tower, +1 Jade Shield. Gives better survivability, since this deck relies on your creatures being active for a few turns.
