Battle in a VR copy of the CW airport. This is a simulation-type environment (that perfectly mimics their power levels and abilities) so they are free to cut loose without worry of hurting each other. X-Men get all their showings from both first class timeline and original.

I feel like Nightcrawler and Colossus would make short work of the street levelers. Colossus can tank blows from Juggernaut, the explosion of a helicarrier like ship in Deadpool, and blasts from Firefist. So Civil War Wanda really can’t damage him even if she ragdolls him. Likewise Storm’s winds are going to immediately curb everyone aside from Iron Man and Rhodey. Their flight gives them an advantage but they don’t have anyway to down Colossus. The ranger options from Cyclops, Storm, and Iceman will also oneshot the Street levelers and tax Wanda’s ability to use her TK offensively. Leaning the Xmen via offensive abilities, but the Avengers can win if they incap Storm
