The ONE PIECE Card Game's 4th-anniversary set now has a release date. Booster Pack OP-17, "World's Strongest Warriors," ships August 22, 2026, built around the Elbaf arc and the Four Emperors, with confirmed cards including Luffy in his Elbaf-arc outfit, Rocks, and Whitebeard.

Four years in, it's worth looking back at where the game came from. OP-03, "Kyodai na Teki" (Mighty Enemies), is an earlier chapter of that story, released back when the game was still finding its footing. It's sold out direct at CDJapan, reachable now through their Proxy Shopping Service.
