Help with Team Building

Hi everyone, I'm level 44 and for the Boss Fight and Gunsmoke Frontline modes, I need to have two well-equipped teams.

I need assistance in forming a second team. Currently, I'm using:

✓Quionjiu v1 with his Tier 4 weapon ✓Tololo v0 with her Tier 4 weapon ✓Suomi v1 with her Tier 4 weapon ✓Lotta v6 with her weapon

I also have Sharkry v1 and Peritya v1 available. I'm about to unlock Sabrina using the weekly boss rewards.

I've included a screenshot showing my other characters in case you have any suggestions. Thanks! 🫡
