32 damage from your hand!

"I greet you." /Gul'Dan

So this is a fun, inexpensive deck that I came up with.  The general idea is to stall out your opponent at the beginning of the game until you can draw your cards that deal damage to everyone.  This can win some games on ladder since it's off-meta and opponents don't necessarily have a plan to deal with it.  Also, most decks have very little healing currently, thus that you have potentially lethal damage even before your minions do a bit of chipping can be difficult to deal with.  It's not some auto-win, but it's something that is a bit different and fun. 

Finding little synergies here and there while using big cards to destroy things is fun my book.

You want to use your Violet Illusionist in order to allow yourself to tap and use your board clears without damaging yourself too much.  Also, useEarthen Ring Farseer to heal yourself or your larger demons to maintain a board presence later in the game.

Making strategic use of Sacrificial Pact can also help.  You might be thinking that Sense Demons near the end of a game is a dead draw, but those worthless imps can actually net you a crucial five health if your sacrifice them.  Don't forget to sacrifice your Voidwalker if it is going to be taken out by one of your own board clears.  Get that value!

My personal favorite is using Felfire Potion to finish off a game with a bit of style, so if that's a possibility at the end of your match, use it!

If anyone wants to make some recommendations, while retaining its core identity of doing damage from hand, maybe there are some possibilities to improve this deck and make it more ladder viable.  I hope you try this out and have fun!
