Removal Tribal

So this is my take on removal tribal. I was inspired by a match against other player that came close to decking him ( He almost decked himself out with the last chanel the tempest). I found that archetype to be amusing because it renders all opponent removal useless so everytime they draw a removal is a blanck and you just drown them in card advantaje.
I have found some success climbing, from Gold I to Diamond I, I faced mostly aggro, that is quite easy if you draw your board clears, you just stabilize with extract and keep drawing cards. The control matchups are 50/50, if you draw gift you just win, I kept setback to use as an expensive sabotage when needed.
Like the name indicates, this is still a work in progress, I am having problems with the power base because most of my power is depleted and makes me very weak against hiper agressive deck when going 2nd. Some of the cards have 3 copies because I'm still deciding what to cut, Banish is actually meh at the moment because I'm not facing a lot of armory. Setback helps me get rid of aegis and sometimes duress the opponent.
I will like your comments and suggestions on how to improve the deck.
