My Discard & Demons Warlock

The focus of this deck is on getting demons early and to buff them.

Try to get some 1 drop demons (Flame Imp, Malchezaar's Imp or Voidwalker) on your starting hand and a Demonfire or Bloodfury Potion. 

This way you will already have pretty strong minions on board on turn 2 or 3.

The discard cards are more a deck filler. Because sometimes you can be lucky with the Soulfire and Silverware Golem, but always be careful if you have Bloodreaver Gul'dan on your hand. But the Discard RNG just makes everything more intense and fun to play.

If you have a bad starting, there's still hope. The Earthen Ring Farseers give you a bit sustain and Alexstrasza can, like always, be used defensive or offensive. And if you get Bloodreaver Gul'dan at turn 10 in most cases it's lethal, if your Doomguards already died.

I played this deck yesterday for a few hours and got from rank 23 to rank 15, but haven't counted my winrate.

You can replace Earthen Ring Farseer with Succubus if you want more of the discard mechanic and higher chance to get a demon.

Here are two matches that went pretty well as an example
