Hearthpwn

As usual I can't make any of the suggested decks so I adapted the Priest deck to achieve the desired strategy with the cards I did have.

One thing I find it helpful to note is what cards I didn't use when I won. Most don't think to include that in their guides but I think it can help people replace cards they don't have. Unfortunately I used every card except Light of the Naaru but I hope others will follow suit. 

I don't have Defender of Argus but if you do I would suggest replacing the Sunfury Protector with it if you do, and if you have 2 of them get them both in if you can as the other buff cards make the statues "more" useful but hardly impactful. Giving them Taunt allows you to buff the minions you need to win. 

For me the win came from buffing Lightspawn with Divine Spirit. I was able to clear his big minions, heal it a few times before hitting it with another Divine Spirit to beat him like a teenage boy's favorite shower toy...
