Today in my free brawl pack I got Barongeddon, then I had a cup of fresh green tea. As a result of that, I think Priest is OP because my keyboard is not a mechanical one. I hope Blizzard will address this issue.
Too conditional lategame power compared to Jaraxxus. I dunno. Mage is good at getting into very late game tho and have Ice Block readily available. Has synergies with Sindragosa's tokens, too. Needs to be seen once the full set is revealed and a meta is established. Jaraxxus can win the game by itself on top deck, this can't and requires other cards to get minions to 1 hp.
