If by "him" you mean Goku, and by "rainbow" you mean rainbow orbs... then yes, it's a bit difficult, but that SSJ Gotenks and TEQ Mr. Buu (from the World Tournament) are good support units if you want more rainbow orbs. I've tried running a team with both of them and the whole field always turned into a sea of rainbow and TEQ orbs (no AGL orbs, no INT orbs, and no STR orbs thanks to SSJ Bardock). My Super TEQ team is not optimal and I haven't even summoned on SSJ3 Angel Goku's banner, so I tried different versions of the team just for fun.

If by "him" you mean Gotenks and by "rainbow" you mean the rainbow star that comes with the potential system at 100%, then I agree with Gilaad, it would be a complete waste of orbs.
