Use Bardock, Gogeta and YEL Vegeta for fighting and RED Goku, PUR Vegeta and BLU Goku for the bench.
Check out the teams page you have the makings for a pretty decent Regeneration team with DK Piccolo, Janemba, and Cell. I'd throw Kamiccolo and EX Piccolo if you got him. And maybe a purple to boost Janemba.
