Hearthpwn

This is a deck which combines multiple aspects of the Deathrattle ability and uses it to take advantage of of warlock cards available in the deck. Useful in taking out annoying aggro decks and builds up to a nice finisher if you play it right. The Hero Power for the Warlock nets you the card draws you need to get your minions out there, and chief removal spells like Shadow Bolt, Darkbomb, Shadowflame and Siphon Soul, you can make the opponent play on your terms and seal it with Double Thaddius, or, if you are lucky, Quadruple Thaddius! Abombination and Sludge Belcher slow down the game to a reliable pace while you formulate a strategy to calculate your next move.

Chief Combos in the deck:

Sylvanas + Power Overwhelming: With a board that is as empty as possible save for a lone creature, plop down Sylvanas and give her a power overwhelming. When your turn ends, you can steal a huge minion for only seven mana.

Explosive Sheep + Power Overwhelming + Shadowflame: For when you need to clear out an opponent's board yesterday. Throw down the Sheep, give it Power Overwhelming, then Shadowflame it to clear out most huge threats on your own side of the board while sustaining small amounts of casualties on your side.

Explosive Sheep + Power Overwhelming/Mortal Coil: A nice early game AOE if your opponent is playing an aggro deck. Explosive Sheep, Power Overwhelming and end the turn, and anything with less than 2 health is gone just like that. Using Mortal Coil to gain card advantage is also a good strategy.

Notes:

- NEVER put Deathlord or Dancing Swords in this deck. The last thing you want to give your opponents in this deck is card advantage.

- Use the Hero Power only when the need arises, and not as often as possible. Siphon Soul is your only life gain in this deck, so try and time your Life Taps with Siphon Soul.

- Baron Rivendare is going to be a high value target in this deck, so time his arrival for when you need to get a needed double deathrattle for minions like Explosive Sheep, Leper Gnome, Piloted Shredder or Loot Hoarder. If the Baron is left untouched, this deck can flip a board in your favor in the course of one turn.

- Darkbomb is better as a removal spell than a face spell. Only use it as a face spell if you are certain you can finish the game off that same turn.
