I'd been considering Ivy, Heather or radiant princess Anemone for my next RG since they all seem like they'd fit in most squad setups (Idol Anemone is an off-brand Kerria with +skill proc and self-targeted +50% skill damage in place of evasion and +defense, Ivy adds slash/pierce weakness coverage along with skill proc and solar burst damage, Heather adds pierce/magic weakness coverage along with skill proc/damage for the whole squad).

The lack of crit boosting on any of them is the only real shortcoming I can think of. Any of them could take June Bride Lotus' place in my main squad though, letting her bolster my second squad along with whoever gets crowded out by Mei when I bloom her.
