Harsh Control

I might remove Silverwing Commander since you are only running 14 units. The warcry effect will probably be a waste if you're rarely pulling units. In just doing a search of 5-cost units in primal/justice influence, there are a few options that would probably be a better fit for this deck. For example, Duskwing Servitor is only a uncommon and would probably always hit the Devour effect if you're playing a lot of removal in a control deck. Commander Ironthorn is a new promo (and cheaper to craft that rares) and has a silence-all effect built in as an ultimate. Of course, there are also a few legendaries that would be a better fit, but I wanted to share some cheaper options just in case.
