Hearthpwn

This deck has served me quite well ^_^  

I haven't played a whole lot of hearthstone, but in wild this deck has done a very good job of climbing me to diamond.

One of the great things about the deck is that it has ways to snag wins against even decks that should counter it.

Since it combines Chameleos and Madame Lazul with Dirty Rat, I've found myself able to kill combo decks quite effectively.  I hold Chameleos with Dirty Rat until they unload most of their minions outside of their key card and then take them out.

I've beaten infinite armor druids with this strat, antonidas mages another similar decks.

Unlike most other priest decks, this deck does not sacrifice board for 1tk.  I've experimented with variations of 1tk Shadowreaper priests and they do work, but I found that I was too easily killed by early board floods or lategame bombs if I didn't get the right cards at the right time.

Likewise I experimented with Galakrond decks, but I found that combo decks would often just wreck me as I had no way to really finish them.

By combining a midrange board centric priest with free pew pews I found that it is often better to just use the free pew pews to gain total board dominance.

From a position of board dominance you have the flexibility to kill them with pews as they protect their face from minions or you can control the board and hit them with minions.
