I would love some feed back because i like the deck however im uncertain if it could be played.  

Not sure it'll work, but I'm looking foward to try something similar.

Anyway, I don't know if I'd include both Bloodreaver Gul'dan and Lord Jaraxxus.

Admittedly, I'm the last person who should be judging a deck - hell, my best decks are Wild Kazakus Mage and Quest Shaman, and those are decks you can be braindead to win with - but I'm kinda questioning having both Lord Jaraxxus and Bloodreaver Gul'dan.  Might just be me, but if switching to Lord Jaraxxus first sets your health to 15, doesnt that mess with Bloodreaver Gul'dan's Hero Power?  Or am I missing something?

Hi, fellow demon enthusiast here, struggling time and time again with a terrible, terrible archetype.

When i look at this, i see a lot of wasted potential in the new cards this looks like its trying to be handlock. The bottom line is that we lack tempo in a world filled with mega-value cards and early game domination.

Your setup here needs draw and you should highly consider running a 2 of Defile or Despicable Dreadlord and take the risk on a delayed Kazakus or Krul drop. You'll want to keep the field clear and you can't afford to be taking needless damage. Grabbing a Bloodmage Thalnos and/or the new Tainted Zealot will net you Defile, Drain Soul, Hellfire, Mortal Coil, Shadow Bolt and Shadowflame value. 

Think of each popular archetype and class and build answers for them. You have no good way of playing around secrets. You lose value on devolve, you can't draw the right answers at the right time due to inconsistency. You need to cut the fat here and really refine what you're aiming to do. 

Thank you for the response, I think it would be a good Idea to drop the handlock package and focus more on stalling to play my big cards. Your spot on with freeze mage and although it's weak I think it might be a good idea to throw in a eater of secrets as a tech card vs freeze mage. The only problem with the deck that I really don't know how to fix is how to tech against devolve if anyone could throw a few cards my way that work well as devolve tech I would love to know.
