There is a brief waiting period before the new cards can be used in Play! Pokémon competitions after a new Pokémon TCG expansion launches, giving players an opportunity to understand and practice with the new cards. Beginning with the Pokémon TCG: Sun & Moon expansion, set to arrive on February 3, this waiting period has changed and several other minor tweaks have been made to the card legality schedule. Cards from each new expansion will become legal on the third Friday of the same month the expansion was released. So you’ll first be able to compete with Sun & Moon cards on February 17, 2017. Additionally, promo cards such as those found in Pokémon TCG Boxes and Collections will be legal on the first or third Friday of the month after the product is released. You can always find an updated list of tournament-legal cards on the official Play! Pokémon Rules and Resources page.
