The question is quite simple, with the major part of the first line-up either dead or too old to hold a shield, who will be the new team and who will be its leader?
For me:
-Leader: Black Panther
-Doctor Strange
-Hulk (because we still need founders)
-Hawkeye (because reason above and his mentor role to the next one)
-Scarlet Witch because Wanda rocks
-Ant-Man and the Wasp because they're cool and fun!
-Reserve member: Captain Marvel because most of the time she will be in space, but answer the call everytime it's necessary.
