Oh god why am I even awake at this hour.
Anyways, before I die and my thoughts go away with me, just do the following:
-Put slashes between the EVs to make it neater and to follow format rules
-Bump the EVs on the bulky booster to 108 so Choice Scarf Latios doesn't try anything cute like KO with Psyshock or potentially lock Volcarona into a single move with TrickScarf at +2. Volcarona won't really mind the sacrifice in 14 EVs here.
-No cute names either (meaning you gotta take "Offensive Quiver Dance" or leave it)
-Offensive Quiver Dance probably wants a slash of Leftovers to recover health over time, and a mention of Lum Berry to recover from random statuses
That's it for now.
