One Piece Card Game Regional Championship -- Los Angeles 2026

You've been shuffling the same sixty cards against yourself for three weeks. You know the matchup spread, the mulligan lines, the exact turn the deck either wins or falls apart. What you can't know -- not until you're across the table from someone who did the same thing with a different list -- is whether you were right. That's what a Regional is for.

The One Piece Card Game barely landed in North America and the competitive scene already plays like it's been here a decade. On June 13 and 14, CoreTCG runs the Regional Championship at the Los Angeles Convention Center -- the biggest organized-play weekend on the Southern California OPTCG calendar, the one people rearrange their month around. CoreTCG is the organizer the serious players trust to run a clean bracket, which is why the room fills with people who didn't drive in to have fun so much as to find out where they actually stand.

Open bracket, two days -- the kind of tournament where the metagame for the next month gets decided in real time, and you get to watch it happen or be the one who decides it. Entry is $37, registration runs through rk9.gg (the platform every OPTCG player already lives on for standings and pairings), and the deadline is June 12 at 7 p.m. -- miss it and you're spectating. Los Angeles Convention Center, 1201 S Figueroa St, right off the Metro Expo Line.
