Kk thanks guys. Ofc all this is still very hypothetical; after playing for some time, I still only have a handful of rainbows (less than 10), certainly not enough to build an aggressive team of that caliber, but always nice to collect info/plan ahead.

I recently got Safforn so I was thinking of how to properly support her, or to put her into my existing team, etc. Looks like I'm better off to build a team around her.

Thought I found some loophole with that Kerria/Safforn set-up; as usual, things aren't that easy/straightforward xD Since I want to focus on counter support, Kerria, you will have to wait for some time longer T_T
