meh. if youre willing to invest into flier emblem shell do alright. preferably shed want a atk boon rather than having it as a bane. SPD is kind of dispensable if youre running brave lance on her. So i mean use her if you want but yeah not the best iv's.
For a brave lance user, this is down right bad.
Her entire role is to swoop in, instantly kill something, then get positioned the hell out. With -atk, there really isn't much point (even IF you have a spare hone fliers from Hinoka)
