Really cool pics of the marvel guys.
Team 2 takes this. They have more versatile move sets than team 1. Speed and strength can only take you so far when your opponents can manipulate time and have access to powerful alien technology.
Except that team 1 can also manipulate time and have access to powerful alien technology.
Team 1 can also BFR team 2 or return team members who have been BFR'd. Superman can push himself and enemies through dimensional barriers, Darkseid can transport enemies through time and space, or he could send his Omega Beams back to in time kill Pym before he created Ultron, or Thor when he is in the Thorsleep.
BFR is out of the question unless only Doomsday remains. Fight would take place in the present in the arena they are fighting in.
