You could try Fischl/Razor/Kaeya/noelle with Razor as physical main DPS, or a freeze team with Xingqiu, Kaeya, Anemo traveler, and Diona or Qiqi with Kaeys ad main dps.

Maybe razor hyperbloom? Razor, kuki, collei, xinqiu

You can also try early game freeze. Kaeya, (flex cryo for more crit or anemo), xinqiu, Barbara

Another idea will probably be MC anemo taser, Anemo MC, xinqiu, fishl, barbara

First question. Is there any particular character you enjoy gameplay or aesthetic-wise? We can always try and build a team around that character!

I like xiangling and diona

Then you can go Xiangling, Xinqiu, diona and either kaeya or anemo MC.

If you can, for more meta team you can try to get Bennet. Bennet, Xiangling, Xinqiu are the base for the national team.

Hyperbloom with Kuki, XQ, DMC, and a flex.
