i was relearned moves for my shadow aerodactyl and i was gonna learn roost but instead of clicking shadow sky i clicked shadow end and then i noticed that i removed my only shadow attack help pls
Unfortunately at the moment I do not believe there is a way that you can relearn Shadow Moves. The only moves you are able to relearn is the normal ones from leveling up. You'd have to stick with the Shadow Moves you have on that Pokemon at the current time.
