You need the link Fierce Battle to some serious damage to Super Vegito, so with this team
Leader: Super Vegito
Kid Buu
Ultimate Gohan
Golden Freezer
Goku SSJ3
Whis
Friend: Vegeta SSJ4 TUR
Good Luck.
This will not work, cause I dont have dokkaned Vegito and I never saw SSJ4 TUR VEGETA only AGL
Vegito wont be your main damage dealer, he is just in the team for LS purpose. You need the link Fierce Battle, You already have Kid Buu, Golden Freezer and Ultimate Gohan dokkan, meaning they have Fierce Battle. So you just need to have Golden Freezer+Kid Buu in one ratation and Vegeta SSJ4+Ultimate Gohan on the other one, Goku SSJ3, Whis and Super Vegito will be floaters. Kid Buu will heal you and since Golden Freezer and Vegeta SSJ4 can tank you wont be receiving much damage, Ultimate Gohan can stun if you are lucky. Forget about Super Vegito dealing damage, your characters with Fierce Battle will do that.
By the way TUR means Trascended UR, is Vegeta SSJ4 dokkan.
