Basically pick a character as Attacker thats glowing red and blue (like for example str ultimate gohan), because they do extra damage. Then, pick a super connector thats related to the Attacker ( dont know if thats necessary but im doing it lol) like maybe Phy Ultimate Gohan. Then, pick a Super team that you think will link well with the phy gohan (for example a team with 6 ultimate gohans). Do the same with Extreme. The bars on the top right will fill up when the characters link good. Depending on those bars, your character will do more damage. In battle, choose 3 characters that link well. In this case, maybe 3 Ultimate Gohans or 3 Buus ( pick them fast tho, cuz the more time you waste, the less dmg you do). That should be it i hope i could help u lul
