Hearthpwn

The goal of this deck was to have a fun combo-ish warlock built with demons that aren't used much

One of the more fun combos in this deck is

turn1 coin ancient watcher

turn2 ancient watcher

turn3 void terror 11/13

Then just hope they can't kill it haha

Or you can go with 1 ancient watcher 1 nerubian egg, then void terror for a 7/10 + 4/4 on turn 3 :D

Alternatives would be early flame imps with void terror in whatever combination you like with the coin. Or late game you can flame imp power overwhelming void terror

One sacrifice you make is losing HP often but you can still draw cards with your hero ability that leads to molten giants 

This deck you tend to start with some small guys in to void terror, or ancient watchers/nerubian egg in to void terrors

The hp buffers tend to hold you off early or buff your gigantic guys later on

You tend to get larger minions so the amount of creature removal is somewhat small

A bunch of minions hurt yourself which pushes you in to molten giant range

Once you get low in HP and the giants are out you can bring out jaraxxus to keep you alive a bit longer

Sometimes the start can be iffy 

I think last bane of doom may come out since it's too slow or doesn't do enough damage and the minion you get is usually pretty poor but it helps as a trigger for nerubian egg if you are desperate
