I was wondering why Pokemon like Volcarona, Giratina, and Reshiram cannot be used in Sky Battles. They can all learn Fly and have wings. Volcarona is floating. Giratina has Origin Forme and by the look of Shadow Force, it flies to use said move. Reshiram is pretty self-explanatory if Black, White, Black 2, and White 2 are any indications. I have tried using Volcarona. It won't let me use it for a Sky Battle. Thank you for the help!
