I just came across a new theory video along with this picture First the theory isn't that the 5th Move will available all the time but it's a attack which we can only access via the new crystals which appear to replace Key Stones. Now the reason for this theory is cause Professor Sycamore studies Mega Evolution and we were introduced to Mega Evolution and given a Key Stone. Professor Kukui studies Pokémon Attacks so he might give us the new crystal. What do you guys think? What do you hope this means?
