I'm curious to see how powerful Grimy Hunter will be in the end. Wondering if it can replace Secret Hunter as the best deck of the class. In my opinion, Hunter got the best cards from the Goons faction and some of the already existing cards have strong synergy with them. Tundra Rhino for example, which is sometimes run in existing lists, can become insane if it gets a +2/+2, almost a Doomguard with no Drawback. Piranha Launcher is also a card I think has been a bit overlooked. The Piranhas are not meaningless (especially since they combo decently with Houndmaster, Rhino and Call of the Wild) and the damage adds up in the end. It has chances of becoming a 1-off card.
I've made a very rough sketch of what this deck would look like. Some of the cards are notably weaker (Smuggler's Crate, Knuckles, Piranha Launcher) and will probably be cut after some experimentation. The idea is to see if the core part (Shaky Zipgunner, Rat Pack, Dispatch Kodo) is strong enough to have a deck built around it.
