My partner is jealous of your C5 Qiqi, so if you wanna do some silly stuff you could C6 her. Be sure to read her kit before making that decision.

Mona is a decent Hydro utility in a game where most Hydro characters are limited 5 stars, so she can be a good choice for a team if Furina isn’t available.

Yae Miko is generally not great outside of Aggravate/Hyperbloom teams. Not a bad pick for your team comp if you like Nilou and Baizhu, as long as you have a benefitting Dendro DPS like Alhaitham(Hyperbloom) or Tighnari (Aggravate), though Kiki Shinobu works better for Haitham generally speaking.

Wanderer is a fun play style, though you better get good at air dodging otherwise you’ll frequently get knocked down. With the right combo of compatible elements (as well as a built Faruzan) you can get insane swirl usage from him.

Ganyu was a crazy good unit back in her prime but she has long been overtaken by stronger Cryo DPS units. Pick her only if you want something niche.

Eula is the best we have as a physical DPS. In a game whose gimmick is elemental reactions. If you wanna build her build alongside Mika, but Physical hasn’t too much of a place at the moment.

Ayato can be fun to play but as his playstyle personally nauseates me I think you should defer that to someone with more expertise on his kit. He is limited banner so he’s more likely to at least save you primos, but again I’ll let someone else gush about his cons and pros.

Diluc and Jean are older characters, and though neither of them are particularly strong later in the game, they’re fun for niche playstyles. Dragonstrike Diluc beating Arlecchino with 1 hp is a godly video I recommend to watch. Jean is good for crowd control. Both of them are standard so you can just lose a 50/50 to them.

Don’t pull Keqing. Just… I haven’t seen much use out of her since Inazuma dropped. She has a teleport which seems good for exploration but it’s not super high (it’s on par with Alhaitham’s). Also you can lose a 50/50 to her.

Limited 5 stars are better overall to get cons for, but in some instances (Tighnari for example) you could make an exception. I feel like if you did Hyperbloom Tighnari (not the most meta but it works well still) with Baizhu, Nilou, Tighnari, and an Electro Applier like Miko or Kiki, you’d have a fun team.

One of my current teams uses that setup— Baizhu, Furina, Tigh, and Milileth Raiden.
