It's Quest Singleton Secret Rogue that revolves around VALUE. Just find the right cards from whatever class and win, easy enough right?
On a serious note, the idea of the deck is a midrange-y/control-y deck with a ton of resources but at its core it can be modified pretty heavily. It's not really competitive although I run it fine at Gold5+ with a 10-3 (obviously at this moment), if you wanna iterate on it just let me know in the comments about the changes you made!
Guide? The guide is: Quest on 1, hopefully you mulliganed for some spells/minions with battlecry, get some value, adapt to the situation. That's it.
