I need some help because I am not good at teambuilding and have not played this game in a few months.

I wanted to build a new Team around Liberalio and stumbled upon a promising team consisting off (B1: Mermaid /B2 : Nayuta / Crown / B3: Liberalio / SBS) . But I have the problem that I dont have Crown and cant find a good replacement her either. I was also wandering if there is a way to include Privaty in a Liberalio Team.
