Hearthpwn

I've seen a few versions of this deck but haven't seen the combos in my version.
You're basically going to be drawing and discounting a shit ton of cards.

There is a few ways to play this deck. 

1. Mainly your going to Shadowstep & Potion Cutterbutter for Mega Discount. 
Play it  with the field contract to just constantly keep drawing. Just be carfeful because you and fatigue yourself. 

2. While you wait for C'thun pieces you can shuffle a bunch of Olgras with potions and shadow steps with Empress in hand you can discover all the Olgras and draw = to the amount in your deck.

3. You can Alternatively discover Deck of Lunacy with wand thief. 

This is in no way a meta deck just a fun combo deck. Cuttbutter combo can get pretty viscous
