League Challenge events consist of only Swiss rounds; there is no top cut to single-elimination rounds.
Players must have a Pokémon Trainer Club account with a Player ID attached, and must have opted in to the Play! Pokémon program in order to earn points and prizes. All participants will receive 1 Play! Point just for playing, and the top four players in each age division will win a special promo card.
Players need to bring their own Standard legal 60 card deck, damage counters, and GX Marker. Entry is Free.
