Hearthpwn

seems really odd that he would be running soulfire over p.o. if he's running leeroy+ faceless, possibly a misprint? 

Seems pretty balanced.  Comparable to shadowflame,  in both cases you're using 2 cards to do a 1-sided aoe to the enemy board. Shadowflame uses shadowflame and a friendly minion, most of the times you can attack with the minion first so we'll call it 1 and  a half cards used. With this you use blood pact and the card you discard. The benefit is it costs 1 less mana but the fairly large downside is you have much less control over the outcome and you take damage from it.  I think the spell is balanced but warlock might be pretty powerful with another cheap board clear, renolock would love not to have to run twisting nether any more. 

I"m loving this deck, the jeweled scarab brann synergy is crazy

I feel so bad at such low ranks D: !  I'M SORRY YOH!!!
