It looks like more than one of a given character, say Loki or Peter Parker, will be working together for the next while in the MCU. It would be cool if a new PVE or two could be setup where you could bring multiples of the same character. The icons might not differentiate on the board, but it would be fun nonetheless.
Would be fun to use a Loki team against a Thor and friends team. Or vice versa
It would be fun to use an all hulk team, since banner and cho are different hulks, as well as a proper spirits of vengeance team since 5* and 4* Ghost Roder are different hosts with different ghosts too
