Hearthpwn

Believe it or not, but this ridiculous deck works.

The idea is simple: you use your Necrium Apothecary to draw solely Anubisath Warbringer and gain its deathrattle. Then with the help of Necrium Blade and Necrium Vial you buff your hand immensely. At first I was trying out the tempo version of this deck with small chargers, which works amazing when you draw Necrium Apothecary by turn 4-5, but if you don't, you are screwed because without buffs the deck is complete garbage. Then I decided to switch to its current version. I added Witchwood Piper to ensure I have Necrium Apothecary much more often by turn 5, and consequently I run no 0-3 and other 4 drops at all. If I am not overrun by some insane aggro by turn 5, opponents usually can't keep up with incredibly overstated minions I start dropping every turn. Note that all my non-utility minions have either charge or rush which ensures me immediate board impact when I play them. 

This deck version can be improved by adding Leeroy Jenkins (a slight improvement) and Anka, the Buried (a huge improvement). All in all, I am very surprised by the performance of this deck, especially since it decimates shamans! I wonder if Necrium Apothecary will be nerfed at some point, the card is busted right now.
