If it can help you, here are my two main Crit teams:

This one as a really simple purpose. Deals as many damages as possible. RRose is the main girl. Weat is here for the x1.65 skill act 1st turn. Swimsuit Sakura is here to give weakness to everyone and Crit. Oncidium is here for the great crit buff.
I use Yarrow for more heavy damages and her speed. But it's not the best choice since she share the same role than RRose. Kugaisou is a very good choice but the team will be slow (492 speed) and it may be a problem on hardest maps where team order is important. Ume or Cactus may be good choice too but I don't have them now .

You can use RG Natsurtium insead of Wheat for more power and damages. Espacially on single bosses.


This one is simple too. Give as much DEF and Crit possible to Pink Miko. Pink Miko is the main here. Anemone and Mirabilis give Crit and bring more counter. Easter Cactus may help with her heal but I will certainly change her in the future.
Kugaisou just bring Crit but I want to replace her with RG Rose.

China Root is a good choice too.


That's my two main crit. One super offensive, good to deal with very agressive pests. And one more defensive, able to deal with big fat bosses with insane HP. Just to give you an example, Pink Miko here was able to solo the 3rd Prison Island Side Map boss. And my first team reach easily over 2k damages on the hardest memory map.
