The official Pokémon website has announced the Spooky Cup (トリックリリック) for Pokémon Sword and Pokémon Shield. Our 8th Generation Online Competitions page has been updated with these details.

Bring Your Spookiest Pokémon to the Spooky Cup Competition

Load up your team with your most spine-chilling Pokémon and take on other Pokémon Sword and Pokémon Shield players.

Just in time for the Halloween season comes a Pokémon Sword and Pokémon Shield in-game competition in which only the spookiest Pokémon can participate. The aptly named Spooky Cup has Trainers taking part in Double Battles with their scariest-looking Pokémon partners. As an added twist, only the final evolved forms of Pokémon can battle—for example, you can have Crobat on your team, but not Zubat or Golbat. Trainers who participate in at least one Battle, regardless of whether they win or lose, will earn 50 Battle Points, so assemble your best team and prepare for a challenge!
