5* Mister Sinister
I recently got a 5* mister sinister after V4 exploration. The main question is whether he is worth a mutant awakening gem (I have 3). The secondary question is whether I should r3 or potentially r4 him. I think he’s a pretty good champ, and I like him in the comics, but I want to see what other people think. I also have no better mutants at the moment.
