Game Sync with the PGL
By using Game Sync in your game, you can enjoy a number of services at the Pokémon Global Link. First, your progress and records from your adventures in the game will be displayed on your Logbook and can be shared with other players. Plus, you can participate in Random Matchup Rating Battles and Online Competitions. And you'll be able to use your Poké Miles to play attractions and obtain items from the PokéMileage Shop that you can send to your game.
In addition, you can check out news about upcoming Pokémon events and find useful data, like the records of your Pokémon trades.
