Any rebirth of the Ultimates title should have a core of:
Leader: T'challa
Carol
Strange
and should probably be called Ultimate Avengers instead.
If you are going to have what is basically an Avengers off shoot type team, they need to have what is likely the core three members of the next chapter of the MCU.
I reject all other teams Ultimate teams without this format.
Other 2-4 members of the team aren't super important if the core is in place. As long as they don't completely nullify why a core member is there. Which is why I don't like Adam on this team because he is basically just Carol and T'challa combined into one hero. He makes them both redundant unless you have a very specific reason they are there.
