One experiment we've been eager to try is mixing the Explosive Evolution card from Galakrond's Awakening with Zentimo, as we can buff 3 minions at once! The early version used copies of Mutate instead of Murmy due to the synergy with Zentimo, but Mutate was often stuck in hand, and we needed more early minions to target with Explosive Evolution, so we swapped them out.
