Unusual demons deck woo hoo

I have been working on a demon deck with demons you never see used which is turning out real fun when it works. Needs some tinkering and probably won't work at lower ranks yet :P The goal is to have a warlock deck that isn't the two main types and that benefits greatly from the upcoming expansion. It also needs to be fun: http://www.hearthpwn.com/decks/62666-darkness Would be neat to see this one played on the show and if there are any working improvements to it
