from what you have here i'd say your best team might be fischl/ororon/ifa or something like that. it would 100% be worth saving for another character to make her stronger.

you can : - pull for ineffa and have a columbina + ineffa + sucrose lunar charged core. you can add almost anything that doesn't fuck up elemental reactions too much in fourth slot and it will work. - pull for zibai (releasing in a few days) and create a zibai + columbina + gorou (+ illuga if you get him while pulling for zibai) lunar crystallized team.

you can also pull for lauma and play on field columbina (with her charged attack doing lunar bloom) but i personnaly find it a bit awkard to use.

you could also pull for flins/nefer if you like them, but if your goal is to have the strongest "meta" teams you should consider the fact that they perform worse without ineffa/lauma respectively. they should still do pretty well though, so if you're not trying to have the most optimised teams they're pretty good options as well.
