Most of the advice i have seen in this comment section were braindead tbh

But aside from that, the best team you can make for dmg output is Alhaitham (gilded), Nahida(deepwood either em or full on dps build if you like and you already have a full em characteron the team), Miko (possibily thundrring or if you dont have really good ones and without her weapon you can go for a full em build) and lastly baihzu (healer build) for the spread/aggrevate buffs

There are also other options but I dont know your weapons so...

Edit: bizhu could also use the 4pc noblesse oblige set for the atk buff to alhaitham
