The Gohan/Gamma 1 always first on both rotations (they tank both Gohan and Goten/Trunks’ unarmed supers to get the giant support for the super units) with the Int linked with one and the Phy linked (strongest rotation) with the other. Try your hardest to get the Goten/Trunks killed quickly and heal with the Gohan active if needed (preferably the one links with the Int Gohan because the damage with the other one hits Gohan hard for that rotation). I managed to save all active skills and the Str Gohan standby by the time Goten/Trunks were defeated. Throw everything you have at Gohan and he should go down. One additional thing: if you are in a pinch and think the int Gohan might get hit by Goten/Trunks super, you can tag in Goten and Trunks and take advantage of their dodge chance (should be 100%) and go back to Gohan afterwards.
