Why can mega-stones be traded to sw/sh but not used?

Question

well mega stones can go to sword and shield but why if not used. why didn't the creators remove the option of getting them to the games. I didn't try it but I searched it on pokebase

Comments

Game Freak love leaving old unused Key Items in their games

Answer 1

I'm not sure where you got this information. You can't transfer a Pokemon to Sword and Shield if they're holding an item.

Items can’t be transferred to Pokémon Home or Bank, period. Mega Evolutions don’t exist in Sword/Shield.

Mega stones are in the coding and I've seen people spawn them in when the hacked raids were a thing but they have no use

This means that you can attach a Mega Stone to a Pokemon if you hack one in, but nothing will happen. Only Game Freak knows why they didn't remove them. It may have simply been easier to keep them in, rather than taking them out.

Hope I helped!
