Hearthpwn

I'm not going to lie, this deck is fairly memeish, but it is also reasonably good.

The basic idea is to copy Mo'arg Artificer with Felosophy, and then use them for some rather large spells (be it Eye Beam for 12/24 or Chaos Nova for 8/16). Combined with Cycle of Hatred, it can create a huge board swing.

All your other demons are good to copy as well, so don't feel you need to wait for an Artificer. And if you can, play your imprisoned demons the turn before you play a board wipe so that you come out of it strong.

There are a lot of other surprising interactions built into this deck for those who love to meme:

• If you kill Magtheridon's wardens with Cycle of Hatred, you get to keep all the 3/3 spirits it creates!
• If you have Khartut Defender on the board at 1 life, and you play Headmaster Kel'Thuzad and Immolation Aura, you get 2 fresh Defenders.
• If you target your own Magtheridon or Imprisoned Antaen with Maiev Shadowsong you will get their awaken triggers again.
