That's a nice squad. For Crit+Counter team, I would see Tampala here. Just for a bit more Weakness and HP drain. Four O Clock is a nice choice too if you use a full setof ATK debuff FM.

For your 3rd team with Balsam+Silk Tree+Cactus, be careful. None of them has skill act and you may lack of it. I used Balsam and Silk Tree in a team with only 1.4 skill act (other girls where RRose, Oncidium Valentine and Wheat) and I regretted it. If I learned something in this game, that's you should never underestimate skill act on crit teams. Crit girls without skills are dead girls.

In your 4th team you could add some negate damages if you can. That's a good thing nowdays.
