My overload team is pretty strong already, so I thought it must be time to build a new team in case my enemy is immune to my team (I almost finished Inazuma)

I'd like to know what reaction would be best for me at this point in the game.

Also, do I pull for Columbina? I have enough wish for her, but I have no idea how lunar reaction works and I'm scared a new reaction would mean crazy investment. Can I just put her with Aino or something?

I know this screenshot doesn't help much but I've included it just in case. Any advice is very very welcome!
I think I need more team than overload. What should I look for?
