The first two people I played against in my first MSoG arena run had to add me to tell me I had a 12-0 deck.

Is it really that good? I don't play that much priest or arena.
Looks like a great deck; aoe, removal, draw, nice taunts, that said most of my decks hit 5 or 6 wins before the real decks show up. I think it can go the distance though.
