So now that I got 19 rainbow girls, anything specific I should be doing with this aside from type matching?

Just trying to set up a good whale team and concept missions do need different formations.. I can more or less keep things this way for the event stuff...

Also, this image is old cause Dend is bloomed, Clover is evolved, and all my non evolved is lv60 (With everyone here having 100% 2nd affection)
