Out of those you should kn ow that Mountain Lily is very strong stat wise and has a good 1st turn ATK buff, Geranium has the 1.2x skill activation and that is very strong while Anthuriums +150 speed really helps to get the squad you want most in the right place.
I would suggest getting the current re-issue girl because she has the same 3rd turn 1.2x skill rate as Tachibana and the two of them on a team generally kills anything and everything on that third turn. Especially if you add that little red head pierce girl that adds +15% atk on turn 3.... you have her but I forget her name... wait it's Star Lily I think.
