The way i see it is Kayana great for Counter/crit team but not much else. Has no skill act. Not as good as Tarragon by a longshot.
I picked up the dressblooms and will target her next year. I have Hydrangea done. Still need high ampy on Tarragon and RG Rose.
Want to get Hollyhock next which will finalize my 4 main teams which are all 1st turn crit/weakness.
