So I wanna preface for this deck that while I was making it I could help but notice the synergy of Unending Swarm with the new hero power boosters like Free Spirit and Groovy Cat. I think on that combo alone you can do some nasty things, I'm not going to refine that list for that now but it's definitely something to think about.

Edited: 4/3
added Amalgam of the Deep for the busted idea of limited discover options on Quilboar! (take notes everyone!) If Amalgam of the Deep is used on a Quilboar, the only options available will be Zok Fogsnout , Hench-Clan Thug, Rowdy Fan, Mistake and The One-Amalgam Band. Seeing as this deck has 3-5 different minion types The One-Amalgam Band is a decent option to flex into, But it also means that Zok Fogsnout is also a consistent discover option for some late game power.  

Important note is that cards that Discover do not discover themselves. (You can't use Amalgam of the Deep to discover another Amalgam of the Deep ) To hit the Quilboar jackpot early I also added Hench-Clan Thug which also has slight synergy with our deck archetype
