Yeah, this whole re-roll stuff will be a test of patience.
I already needed to let go of Alpinia and Iberis (among others) to keep on going.
EDIT:
Ok, I think I'll stick with Anemone, completing my collection of her reprints by the way.
I had Snowdrop (who I wanted to have in the past) twice, but I'm not sure if attack down teams are even viable nowadays.
