I just had a pretty insane game with it. Tess was 1 mana due to galaxy... I played avenging wrath and tess in the same turn, then shadowstepped it... played a efw turns later with pyroblast in hand to finish if they didn't concede from being at 2 hp. And I was like 30+ due to getting armor off this warrior minion I kept getting back.
Yes, it's a very fun deck!
