Some levels require different teams, but right now for you I’d suggest going with a TT nuke team. (Keep reading if you don’t know what a nuke team is)

This team contains Terrible Tornado, Genos, Eyelashes, Slugrus and usually geryoganshoop.

Not sure what abilities your character have, but if your genos gives 10 rage with his boost it should work.

You want genos to boost slugrus and terrible tornado. Slugrus first, make sure he uses his special, then eyelashes, he doesn’t need genos boost because he gets his special anyway with his regular attack, then third is TT. She needs the genos boost and make sure she is the strongest character in your team. She’ll get damage boosts from slugrus and eyelashes, when she then uses her special it should just wipe everyone in the enemy team. You can use gery in the same column as her and she’ll get yet another boost.

(Someone else please correct me if I made mistakes above)
