The official Play! Pokémon rules and formats for the 2019-2020 season of VGC tournaments have been updated by the official site. The VGC 2020 rules will be changing on January 4 so that everyone will be playing Pokémon Sword and Shield and the standard battle format style will be Double Battles. Players will be able to use Pokémon from the Galarian Pokédex except for certain Mythical and Legendary Pokémon. Players will be able to Dynamax their Pokémon but since players will be more likely to encounter certain Gigantamax Pokémon than others until early January then there will be a list of Gigantamax Pokémon that can be used although this list will be updated with other Gigantamax Pokémon every few months in the Play! Pokémon VG Tournament Rules and Formats document.
After more than nine years, Pokémon Global Link is shutting down in late February 2020. As a thank you gift for using the service, Pokémon Sun, Moon, Ultra Sun, and Ultra Moon players can receive Fennel's Munna.
