For your Cattleya team, I recommend Almond. Her bonus +100% HP is good for survivability and her +30% skill dmg and x1.36 skill rate help Cattleya a lot. And obviously you must use 5 the +10% skill dmg for magic FM. Five times +10% skill dmg with Vervain ability activated is insane.

My super combo is still the same:
Saffron+RG Camelia+Kerria+RG Heavenly Pinkladies+Maid Cowslip.
Cowslip bring a new healing ability with x1.36 skill act instead of x1.2. Saffron and Kerria have both more evasion than before now and intercept. And more Def.
Saffron got a natural provoke so, you can give her another kind of FM.
