I wonder what it could be, it seems to include all the big guns of marvel. The names that piqued my interest the most were
Namor - He flooded Wakanda and i wonder what changes he's suffering to his mutants powers due to the Phoenix like the other X-Men who were possessed
Cyclops - He's probably the most popular marvel character in comics right now and in the marvel universe all eyes are on Cykes at the moment
Cable - He's started his new squad and the Avengers just witnessed him, colossus, domino and his crew just murder a bunch of "innocent" people
Also lol at Gambit. I hope marvel finally fucking figures out what to do with him considering his one of the greatest xmen and one of the most popular yet they cant get a good writer for him since like the 80s, hopefully they fucking finally use him properly and do him right like the 90s cartoon
