First of all its great to see a rapid synch ressurgence, it really only takes one story.
and second im pretty confidant synch is on the x-men team since its a in universe vote, and Synch just went trough an odyssey type of heroic journey for the defense of krakoa, spent 500 years on it AND DIED for it and brought with him extremly important intel.
Word runs fast on the island and no way synch doesn't win a spot on the team, he's probably going to get a song or a play or two over his heroic deeds.
