Mr.Negative is my favourite card so far but I'm having a hard time trying to make a deck with him work.
This is my latest attempt, moved away from the on reveal focus since I don't have Wong and Odin becomes unplayable.
Crystal is there either to try and find Mr.N or try to pull the negated cards after playing him, she'd probably get replaced by Mighty Thor if I could.
PS. I don't have Sera.
