Having recently entered pool 3 and after unlocking Mister Negative, I wanted to create a deck that works well with or without him. The curve is a bit weird and quite often you have to wait a couple of turns before actually playing a card but: -Pretty much everyone benefits from being Mister Negative'd (except for Odin) -If you get Sunspot early he can soak up some energy or you might just be stacking cards to play Devil Dinosaur later on -Storm & Professor X are great for disrupting your opponent's plans -White Tiger,Ironheart & Odin are a great combo, pretty iconic if you Mister Negative the first two -Jubilee and Leader also work well with Odin
All in all it's a versatile and fun deck, hopefully you don't get Cosmo'd out of existence
