A team build that is best for challenge events

I am also willing to awaken, eza or seza any character if need be. I also only have 27 keys for the Portal of Memories so I don't know if I can fully awaken a character if their awakening event is behind the Portal of Memories.

agl gogeta - 7th years (phy g4 and teq ssg) - teq super vegito - gofrieza - agl fpf/teq grapegeta/str ssbe (up to you/id lean towards either fpf or grapegeta)

7th years slot 1 on their first turn, fpf/grapegeta can slot 1, you can also use reverse exchange on the anni units to slot 1

id float gofrieza just to be safe and have the exchange available (if your gofrieza appears on turn 3 you can slot 2 them instead)

with fpf you mean LR agl full power Frieza right? And which character is Grapegeta? I am not very familiar with character name abreviations/nicknames.
