Hi, I'm not sure if your deck has enough lategame, because I think kazakus and krul+doomguard aren't enough. I think you have a lot of cards to fight for early game, but I don't like some of them. Since you have PO+faceless already, add leeroy in here. Defender of argus is also good and commonly played in renolocks and maybe jarraxus/ragnaros/mountain giant could grant you more threats. I'd cut drain life, summoning stone and harvest golem for leeroy defender of argus and one of those, if you have them: jarraxus/ragnaros/mountain giant. Also you are seriously lacking emperor, which is a must have in renolocks and make leeroy combo work. I'd cut felfire potion for that and I like mistress of mixtures as good 1 drop to follow up with tap and trade to heal back, but I'm not sure what could go out for it. I like krul as cool legendary, but I'm not sure, if there are enough good demons in standard to be good.

To compare I tried to build renolock with krul for wild, because wild has voidcaller and malganis, which makes krul much more powerful. But my version is far from refined as well. So if you want to help me, look at my deck and description and give advice, if you can think any.
