A real conundrum

So in my first circle on the new banner, I pulled a +Spd/-HP Kana. Perfect IVs, but that Water Breath with it’s built in Bracing Stance looks really nice for Fae, especially since ranged units all but vanish at top scores. Should I hold out hope of getting another Kana, should she fall to make my Fae mightier, or should I just keep Fae with her Lightning Breath?
