Here's my take on a very popular DH archetype. I've used this deck to climb from D5 to my first ever Legend (I'm not much of a ranked player, so it's quite an achievement to me). It allowed me to get a very nice winrate of 77% (17-5). Before that, I used to play a different version of this deck, with Skull of Gul'dan x2, Battlefiendx2. After the latest patch I decided to cut both of them, replacing them with Blazing Battlemage and Priestess of Fury. It turned out SoG was not needed - the deck guarantees you decend draw and Altruis combos are not as spectacular anymore - and Battlefiends were simply too slow. I consider Priestess a nice addition - a sticky minion helps you to set up a killing blow, especially against classes with plenty of boardclears.
If you find it interesting, I will post a muligan guide and some gameplay videos. Hope you enjoy the deck!
