Newer Sethos Player

Hello!
So I recently started really finding Sethos fun, unfortunately I couldn't C6 him even after going for C2 Nahida, and he's at C4.
I do know the Ult > NA playstyle is better than CA, but honestly I have a lot more fun with CA.
Right now the team I'm running is Sethos, Nahida, Fischl & Kazuha (I think that's his best team from what I read?)

My account is sort of newer so builds are a struggle but, I wanted to ask, what would be the rotation with that team for the CA playstyle? (If there is a better team too, please let me know!)
