This is a great deck, and I am enjoying it! However, both games I test-played have seen me run out of cards, with an eventual win. Very powerful if you can catch your opponent, though. BOOM!
You have to be careful not to outplay your deck and get left with cards you can't use, like Shadow Word: Death (if you opponent is left with few cards and nothing powerful). I might replace one of the Shadow Word: Death with a Mind Blast, Holy Fire, or a Divine Spirit and see how that goes.
Thanks for sharing!
