Congrats. I guess having RRose alives for the real boss helps a lot.
I just don't know how to deal with that this time. The Nushi would be doable if it didn't have that crazy buff after some turns. I guess they REALLY want to force an evade+miss meta.
At least it's not a stupid stack-your-best-Crit-and-sweep stage. It needs some reflexion. Too much reflexion.
edit:
Okay I don't know how but I did it. Kerria & Pinkladies are the bests (helped a LOT by Saffron magic type buff). And RRose did everything by finishing the job.
Maybe I should leave the Crit side a bit and focus more on Evade girls. I don't have any good out of Saffron/Camelia/Kerria/HFPinkladies
