Adaptable to any spot on your team like Helenium Easter is only with 1.65 first turn skill act like Daisy has (she will likely put Daisy on the bench for me or possibly Waterlily bride, but she's so damn cute)
Wouldn't say she is better than Sakura, they are each better in different situations Sakura better against bosses.
I would say that I will use her more than Sakura because of her flexible placement on a team (that needs 1.65)
Another one coming that interests me is in event 69 http://flowerknight.wikia.com/wiki/Easter_Cactus
we don't have anything like her right now. Remember those rainbow medals don't expire and we probably getting a cheap ticket next week that will
