Rosé as Leader, Merged Zamasu as Friend, Goku Black for Ki support, Omega Shenron for debuffs and additional attacks, Buuhan as healer, and then LSSJ Broly and Beerus because they're the only ones left. Although you could bring Oceanus instead, who's pretty weak but can seal the enemy's super attack and shares the GT link with PHY Omega Shenron (very useful against STR Omega Shenron).

The very first time I did it, I used a Super team, but I think Extreme is your best team.
