I would go Life and Death, my Summer Corrin is similar, +spd -def. But Fury is nice if you go desperation as its a bit easier naturally to get into range
either is good but I would go LnD for maximum power, especially if Blarblade. She can nuke on flier teams
Yeah I already have Desperation 3 on her, so I think I'll just slap LnD 2 on her now for the time being and when I get a four star Sothe or bad IV Minerva I'll sack them later.
