Gameplan

So, this deck intended to feed upon the early greedy decks in the new expansion meta. Sadly, there are quite few of them, but it can still win. Just try to keep the board, and hope for good draw.  Protect your Knife Juggler, and try to make the best out of the first few rounds.

Synergies

There is a Galakrond Package: Dragonblight Cultist, Fiendish Rites, Devoted Maniac, Galakrond, the Wretched and Kronx Dragonhoof. Whenever I managed to fully invoke Galakrond, I won the game. There are a lot of demons with taunt, which proved usefull, as my HP was usually in the single digits.

There is a small removal and control package, Plague of Flames, Voodoo Doll, Mortal Coil and Dragonmaw Poacher: Plague of flames is really usefull in the early and midgame, where a few imps can trash big things, and Dragonmaw Poacher was (when it was used, in 21.4% of the matches) a livesaver. Voodoo Doll is great with Grim Rally and can clear of big taunts.

For card generation there is [Hearthstone Card (Cobalt Spellkind) Not Found] and Witch's Cauldron, because the 1-mana spells of warlock are great in this deck. The cauldron is a fun card, that can win your games, as well as a soft taunt.

Budget

For a budget version, you can take out Kronx Dragonhoof (but he's great! You should craft him!) , and replace Witch's Cauldron or Voodoo Doll with Mecharoo, Hench-Clan Hogsteed and another Cobalt Spellkin.

This would make the cost 2720 dust, provided you bought a single pack of Descent of Dragons and own the Galakrond.
