Okay, that's interesting. As you already said,
Jack-in-the-pulpit and
Water Speedwell are totally okay.
Rainbow Rose and
Crinum are to notch too.
•
East Asian Eurya is interesting as very specific Magic user support. I could recommand but later.
•
Adenium was solid in the past but she suffer from being an evade girl pre-rework (like 99% of 5* evade girls...). Still not that bad.
•
Butterfly Bush is decent too. Not awesome but better than nothing.
•
Tiger's Claw is an okay support, even as 5*.
•
Harujion is kinda meh but she may be a choice if you want speed. Crit buff is still good though.
•
Spring Star too for the crit. But it's better to wait her school version reprint event. She was an event 6* and she is just awesome. I guess she will be available in the reprint event girl shop for a lot of reprint crystals. She should be here in two weeks.
•
Four O'Clock and
China Root if you want counter+crit. Counter is awesome mid game when nothing can kill you but fail later when anything hit like trucks with tons of HP. Stupid power creep to the moon
•
Syngonium help too for a counter team with her great def buffs.
•
Spider Lily is great. Disgusting 60%crit dmg (second highest crit dmg for 5 behind Bluet if I'm correct) and usable debuff. She really lacks atk buff though.
•
Pinkladies (Princess of Pure Flower) Good but the weakest Pinkladies version I guess. Flower Saint is way better.
•
Dragon Tree is high risk high reward. I don't think she is that great but Combo Hit is a thing and may get a lot of kill if you gives her enough power.
•
Statice. Never played her but I know some people liked her as support.
•
Manchineel is an intercept girl and one of the few 5* with actual evasion post rework. No reason to not use her in your evade team before getting more actual 6*.
•
Blushing Bride (Costumed Apprentice Teacher) is a decent support with Crit+Negate damages
•And
Artichoke can be a good attacker.
I didn't checked all the girls. Only the ones I know they are or were at least decent. I could have missed some things. All of thoses won't change your team to make it awesomly strong. That's the job of pure 6* and only a handful of promoted 5* have insane potential. But decent promoted 5* is better than just nothing.
Having 12 rainbows at your point is not bad at all. I got my first rainbow after almost 6 months. The game was less hard and we didn't have any free 6* though. And a really unfair gacha (basically the salt ticket gacha but with FS).
At the end, you did not the 3oo FS new year gacha? Or did you forget about the free 6* ticket in the warehouse?
This is just a Ghost Weed skin. And it's a free one. You already have
Ghost Weed (Princess of Pure Flower). You can use it on her (click the shoe icon on girls profile to change their skin). I think regular
Ghost Weed is the weakest of them (useless out of Solar Teams and there is better Solar Girls anyway).
