I was wondering how you would improve this control shaman deck I'm experimenting with.

It's currently positive in winrate, but it still feels semi-clunky. I've tried Astalor, but he didn't do much so I swapped him for Okani instead. The deck is not doing well against other control decks eg. Blood DK / Priest, so I tried adding Drakuru for something more later on, but it doesn't feel like he either fits or he's too situational 

The audio medics I added to try and delay early aggressive decks and it's been fine 

I would really like some feedback and suggestions, because the deck is so much fun and it performs surprisingly well. I just want to know what I'm missing to optimize it even more.

I haven't felt like any of the cards are "dead in hand" , they just sometimes feel un-impactful. Thank you! :)
