Team Black Widow (MCU)vsTeam Captain America (MCU)

Team Captain America (MCU) Team 1 only has a chance to win if they really fight as a team, have perfect teamwork, etc... Erik would take down Tasky and Bucky as his stregth and durability due to suit is a real deal for them... Natasha and Alexei can probably deal with Cap (MAAAAAYBE), and Yelena + Melina can do some work win T'challa, and as soon as Erik comes from the previous fight, he might be able to pull a win...That is the only one winning I can see for a Team 1

Team Captain America (MCU) Cap * vs Melina, Yelena
Bucky * vs Guardian, Natasha
Tasky, Panther * vs Killmonger
