To make it short, i'm very poor and unlucky in this game.

I got Columbina cuz I liked her, but i'm wondering how well she works with Nefer without Lauma.

As of now, my team is:
Never
Bina
Furina
Jahoda

If needed, here's my second team:
Mavuika
Chevreuse
Iansan
Bennet

Mavuika's team probably could be improved, by idk who to use to facilitate elemental reactions. I do have Yae, Raiden and Fischl but i'm not whether it's good to use them here.

Any help for me?
So, i got Columbina but i'm poor
