On October 30, 2018, the Pokémon TCG Online officially retired the ability to purchase Event Tickets for use in the game. Gem purchasing, which was limited to Canadian residents, also ended at that time. Players will still be able to redeem Gems for in-game items until December 10, 2018. After that, all unspent Gems will be automatically converted into in-game Pokémon TCG: Sun & Moon—Lost Thunder booster packs and Trainer Tokens. Event Tickets will still be available via Versus Rewards, so players can continue to participate in tournaments.
