Party Room

Use Wump & Friends (TM) to activate Throne Room for extra hilarity (and use Wump normally to get your infiltrates.) Credit to my teammates, who built an actually good yeti deck which I stole and perverted for my nefarious designs.

Improvements may be made to the power base; I tried 4xShugo Standard but it wound up giving me depleted power too often. You may want Cobalt Waystones but be aware your Seats will come in depleted more often.

In most match-ups, you don't want to wait til Wump is already down to play yeti you have in hand. Use your yeti to beat their face in as per usual, Wump and Throne Room are nice bonuses that happen along occasionally. If you're mulling hard for anything, I'd take Throne Room over Wump, because you're fast enough to get in lots of hits even without Wump's ability.
