Lightweight
I used a 5* r4 duped antman to take out each magik and iceman. I used a 6* unduped storm R1 to take out the champ each time. Once she was at 21% to start the fight and still destroyed him.
Full team included a 5* unduped r4 magik, duped r4 gwenpool and duped r4 CM. It was only lightweight but managed to finish by only using one 20% boost and no potions.
Just putting out a different lineup so people might try something different.
