"When you collect a Pokémon that is visiting this game from Pokémon Home for the first time, that Pokémon's current strength will be used to determine its strength in Pokémon Champions. From then on, even if you make changes to that Pokémon in other games, some changes will not carry over to Pokémon Champions.
How does this apply to new ribbons/marks gained? Can I get fun new titles for Pokémon I've already sent to Champions before?
