For now, I think I'll use her in my regular intercept team to replace Golden Lace. At least until I can get Blueberry Easter.
She would be good in offensive team but she really lacks of self offensive buff and I lack of good support girls like Hinoki School.

For EX maps, I'll stick with Bluet+Adlay+Spring Star School+Asian Birch+Tritoma. That's by far my best regular team ever made.
For the hard Stuff, the classic Sigilaria+Adlay+Zinnia+Spring Star School+Corbett will still do the job.

I really hope we could get a rebalance someday. Most of pre 2020 girls are meh or useless. That's hard to use them in meta right now.
