A question about the red haired Waifu...

So... yes I know I'm talking about Bridelia a lot but bear with me... What do you think of this build? Could I use it or should I scrap it? I know I know... yes I will give her a brave bow if I pull a Klein or Gordin!

Cupid arrow+
Draw back/ardent sacrafice
Luna/Draconic aura
Swift sparrow/L&D
Desperation
Threaten Speed
+Atk or +Spd seal in case I get bad IV, otherwise it's flexible

I want to use this build to do a lot of in game content because I don't do arena much. I play to enjoy the game not to rage at arena. Especially because I almost made it to tier 20 but I lost the last match to a full team of brave heroes. I just appreciate the feathers and orbs.
