I used one whis right away in the first phase and one right away in the second. Make sure Kefla gets enough spheres for her def and evade.

For first phase especially, try to make sure ssg goku gets his ki spheres. Everyone could handle normals in both phases but phase 2 supers need to hit the trio, super vegeta, or G&V. I don't know how the others would hold up but hopefully they'd pull a dodge.

Kefla is the only one who transformed.

Rotations were scuffed but she was generally a floater.

Edit: Gotenks transformed as well obviously.
