Key Card (that I still have not gotten to try out ): Metamorphosis
Finishers: Vaath, Blood Rage, 1 damage ping
Combo Cards: Everything
Is it questionable to run Adjudicator in a deck where almost every card deals 1 damage to everything? Maybe. But he helps get Finality out a turn early, which can be a game-saver.
BTW, Duelyst is only fun in Silver now.
