Hearthpwn

Hello all. This is the first deck I've posted. I would love help making my glass cannon rogue more durable and consistent. The main cards in the deck are malygos, sinister strike, razor petal volley, eviscerate, shadow caster, Barnes, vilespine slayer, journey below, xaril, and shadowstep. The idea is to get at least 1 maly to stick to the field for the kill spells (usually sinister strike, eviscerate, and maybe a razor petal or 2 if still available. ) The ways I have achieved this so far (assuming I live long enough) is Barnes out maly and shadow step or give it stealth obtained from xaril. Shadow caster a shadow caster from Barnes and on turn 10 maly shadow caster. Wait till turn 10 maly stealth from xaril. Etc. Journey below gives more chances for xaril. Also yields bloodmage thalnos, sherazin, moat lurker, and other potentially useful minions for extra utility. All other spells are to kill minions to help me survive longer or draw cards. Not many minions because I don't want the pool too large for Barnes. No auctioneer because it's not a miracle knock off. 

Thanks for stopping by to check this out and any help is appreciated. I really want to make this work.
