what does your demon deck look like? I'm struggling in that same range, went from Reno back to secret paladin, to druid, and now zoo at rank 7. I played most of the season with Renolock but it feels so uneven sometimes, priest/warrior i'm set, aggro if i don't draw well i'm doomed. And then secret paladins....
At work so I'll do it from memory. 2x Voidwalker 2x flame imp 1x owl 2x knife juggler 2x egg 2x voidterror 2x peddler 2x haunted creeper 2x abusive 2x PO 2x voidcaller 2x argus 2x doomguard 2x imp gang 2x implosion Dr boom mal ganis
I think that's all of it.
