Joseph you underestimate balance on your list. Balance equipped with a myth amulet can be a devastating combination in 1 vs 1, with cards like mutate Minotaur balance will have a vast array of blades to use making them highly unpredictable and very dangerous in the arena. With a new and more powerful healing spell balance will rely less on life school making them a proficient choice
XD that's exactly me. I still can't beat any diviners they are the only school that have a very hard time beating.
