I made a Blackbolt CS for the first iteration of this I was in. I decided to scrap it because I felt he was too esoteric of a character for me to make work. Seeing this Karnak CS is making me wonder if I should bring that back. 4 characters (including Baron Zemo) may be too many, though. Of course, if you'd just rather I not, Eru, that would squash the issue entirely.
