Dodge is fine if you don't mind RNG. I think it's like a 25% dodge rate. Obviously, Ionocidium/Pumpkin/Lycoris are the most ideal units to use, and Waterlily is incredibly fragile otherwise.

Counterattack works great with any attack-down and/or defense-stacking units, since the counterattack is based on the girl's defense.

You should also keep an eye out for any characters with enemy skill down abilities, like Gentian and Southern Cross.
