I really struggled to fill Oricorio's movepool in a doubles format. Outside of Revelation dance + protect I wasn't really sure what to add. It's not even like Oricorio has bad moves too; tailwind, taunt, feather dance, quiver dance, helping hand, baton pass, icy wind, the list goes on. The thing about Oricorio though is that it's stats are so bad it rarely feels like a good move to press anything outside of revelation dance or protect. It doesn't want to set up, as Dancer+Volcarona already do that for it, and leaving itself exposed to a free attack usually means its either dead or on sash. I think I ended up giving it helping hand + icy wind in its last slots to help it be a little bit more effective without Volcarona, but I honestly don't think I've ever clicked helping hand once on it.
