Need help for creating a team for Pvp

I'd say

Pur broly, red broly, red gogeta, grn cooler, red ssj goku (for z-ability), yel black/yel super vegeta

Actually, I think a better team would be sp ssj3 goku purple, sp broly purple and sp super gogeta. This is because this gives you a purple color counter team, which is typically stronger than a multi colored team, as well as a saiyan team. This allows it to gain more bonuses from more z-abilities. For now though I think that saiyan z-abilities are the better choice for now. You should show us your ex character roster as well as they give good z-abilities but in case you don’t have any, you should use ssj goku red, goku blue and Vegeta purple. These characters buff blast attack and strike attack and strike defense, thus making your agressive team more aggressive while also giving it sustainability. If you have ex raditz blue, you should replace sp goku blue with him as health is better than defense for sustainability. In summary your main team should be sp ssj 3 goku purple, sp broly purple, sp super gogeta and the bench units are sp ssj goku red, sp Vegeta purple and sp goku blue.
