I recently flagged this post as not an answer to the question. The flag was declined with the message stating there was no evidence that supported it.
The question is specially for pokemon-x-y whereas the answer is based on new features released in pokemon-sword-shield.
While is the answer is valid for the newer games (which has since been expanded on and migrated to this post), it is not a valid answer for the question it was posted on. With that said, why was the flag rejected?
