The One Piece Card Game returns to downtown Oklahoma City on Saturday and Sunday, November 21 and 22, 2026, for an official Bandai-sanctioned Regional event in Exhibit Hall D of the Oklahoma City Convention Center. This is the second Regional the game's Championship 26-27 season has brought to the city, run under the current Standard format regulation, and it is the largest purely competitive One Piece event Oklahoma has hosted since the earlier Season 1 stop drew a full room back in September. For players chasing Championship Points on the road to nationals, this is one of the must-attend stops in the south-central region.
The tournament itself runs Swiss rounds into a single-elimination Top Cut, open to any player with a legal 51-card deck built around a Leader card from the current card pool. Bandai's official ranking system means results here count toward invitations to later Regional and Championship-tier events, so expect a serious, competitive field: regional grinders from Texas, Kansas, and Missouri routinely make the drive for events like this one, alongside Oklahoma's own steadily growing One Piece scene. Prize support follows Bandai's published structure for Regional events — Top 64 finishers receive an exclusive promo Nami card, every registered participant walks away with Event Pack Vol. 9 product, and Top 8 finalists and the eventual champion receive limited playmats not available anywhere else. Side events, deck-building help tables, and casual play areas typically run alongside the main tournament for players who want to be in the room without grinding Swiss rounds all weekend.
Doors and check-in generally open early both days, with the main event running through the afternoon into the evening on Saturday and wrapping by mid-afternoon Sunday once Top Cut concludes; confirm exact round times and the registration cutoff on the official event page before you travel, since Regional-tier events sometimes adjust start times based on entrant count. Entry fees for Bandai Regionals are typically in the neighborhood of thirty to forty dollars, paid through the official ticketing link, with no walk-up guarantee once the cap is reached — pre-registering online is strongly recommended.
The Oklahoma City Convention Center sits at 100 Mick Cornett Drive in the heart of downtown, directly beside Scissortail Park and a short walk from the Paycom Center, with an attached parking garage, additional surface lots, and OKC Streetcar access for anyone staying in Bricktown or the Central Business District. The exhibit hall itself is modern, fully climate-controlled, and easy to navigate even at tournament capacity.
This is an event for competitive and semi-competitive One Piece players first — casual collectors will find plenty to watch but should not expect a vendor-heavy show floor the way a general card show offers. First-time Regional competitors are welcome and the format is beginner-friendly to spectate, but come with a legal deck list, sleeved cards that meet tournament standards, and a fully charged phone for the pairings app. Bring a printed or digital copy of your decklist, extra sleeves in case of damage checks, and snacks, since round times can run long. Arrive early on Saturday to register and get a feel for the room before the first round is called, and follow the official One Piece Card Game social accounts and the Play!TCG event page for final round times, judge announcements, and any last-minute format updates before the weekend.
