Currently, my roster includes bloomable girls of each type except pierce, so Echinacea is strongly considered in my top 3 choices. I have no more good purples to raise though. It'll likely be Oppaibell vs. Ecchi-nacea... and the one with bigger oppai wins!
I'll be rolling the gacha next week anyway to see if I get something nice before then.
I was about to mention that "White Tiger" likely won't end up in the selection as she was a recent addition to the Premium Gacha lineup. Girls added there after 1/11 won't be part of the selection, per a devnote.
After thinking about it, I might just go with Green Bell, being short on magic types this time, unless I get something better with my next batch rolls. Her ability profile is close to Dahlia's, to go with higher overall power (13100+5672+2178) and higher skill proc (24% base, 34% max).
On top of skill up abilities, Laurentia's or Aloe's other abilities should synergize very well with the girls in your roster. Personally, Laurentia because I find shine crystal abilities just as essential as solar drive damage on a solar drive-oriented team.I am looking at Apple, Aloe, Laurentia, Flamingo Plant (Justica), and Dogwood (Yukata).
I am leaning towards Lauerntia or Aloe because Lily of the Valley, Alium, Gerbera, and Glory of the Sun work with Solar drive.
I got a Gerbera x2 (Lv.2 skill, two equip slots), Glory of the Sun (Leucocoryne), and Alium along with a gaggle of 4*s (including 3 more Di Yu) since the last time I mentioned what 5* I have gotten.
Lots of +x% attack but I need to bloom most of my 5* to get at it.
The other choices are solid though as they have bloomed forms. Can't go wrong with any of them, really.
