I've been thinking and I would really like to see a tournament much like the animé has as an option to be given the right to challenge the Elite Four. I would at least have it be an option, with Victory Road still being allowed as a means of challenging the Elite Four. In the tournament setting, I would allow teams to change and have the scale progress from two-on-two, to three-on-three, to eventually having six-on-six in the later rounds. The later rounds would also be quite challenging, comparable to competing against a battle facility leader. Your teams would be healed after each battle and you would be able to change your teams around after each battle. The challengers' Pokémon would scale to an average of your own Pokémon levels, but the algorithm would ignore any Pokémon that is ten levels below your highest level Pokémon. In addition, if you go this route, when you face the Elite Four, their Pokémon levels would scale to your highest level Pokémon and they would have a minimum level of 60, with the Champion having a minimum level of 70.
