Congrats, what was your team?
I switched around.
I started up to 7.5x with Masked Bardock lead, STR Arale, STR Cell, STR Broly (original) for my AOE, along with Super Vegito and Vegito Blue.
Up to 15x used Omega Shenron lead, STR Arale, STR Broly, along with my best STR links for Arale. Dropped Cell because he needs 11 ki for AOE and wasn't at SA10 unlike the others.
At 20x I went with my god lead team: Masked Bardock lead, TEQ Angel Goku, SSJ4 Vegeta, SSJ4 Goku, Super Vegito and INT Gogeta.
All with an LR Broly friend, sometimes Blue Vegito if I couldn't find a Broly after 5 refreshes. The whole tactic was just getting my Broly friend in rotation without dying. Using orb changing items, +ki items and ushers/sealers if he wasn't on the first rotation.
All in all, life is much easier with a LR Broly yourself, but perfectly doable without having one yourself.
