Party Protocol

I've only really tested this deck in gauntlet as I built it for something fun on the grind. It's mostly an aggro deck but can beat a stalled board by making sure to combo off Wump or Slushdumper.

The Mirror Image is most often used on Wump as that's the goal the deck.
Tried to stick with yetis that have infiltrate or on damage to enemies to really use Wump's ability to the fullest.
If you stack the Wump, Party Starter the Scouting Party can easily hit for 8+ damage plus net you a few cards.

Slushdumper is another way to trigger the infiltrates on cards if you put out a yeti before Wump.
