Hearthpwn

Chromaggus is the most difficult heroic boss I have encountered so far. I have failed many times with the Yogg tempo mage deck as well as the inner fire priest deck. Due to the nerf of various cards (e.g. KoG, Molten, BGH, Owl etc), the control druid deck no longer works either. Thus I have decided to make a fun deck and see how it works. I have tested it a few times and it's proved to be working if tempo is gained for the first four turns.

Mulligan for Flame Imp, Felstalker and Darkshire Librarian for a starting hand. Ideally, we want to discard those affliction cards with our battle cry cards. The blue and bronze afflictions are most dangerous. Restart game if the discard does not work in our favor.

If everything goes well, we can gain total board control and trade efficiently. The win condition is either buff'ed Tiny Knight of Evil or an early Mal'Ganis via Voidcaller.
