The One Piece Store Tournament promotional cards are a familiar corner of the One Piece Card Game hobby, issued through organized play events at retail stores rather than in standard booster packs. Volume 4 belongs to the 2025 run of these exclusives, and like its predecessors it gave players and collectors a chance to own a character card tied directly to competitive play. Promos of this kind tend to be remembered for their scarcity relative to mainstream sets and for capturing a particular moment in the game's growing following. Monkey D. Luffy, the rubber-powered captain of the Straw Hat Pirates, is the franchise's central figure, and a Luffy card is one that most collectors want regardless of set. This entry, numbered 106 in the series, presents him in a design that suits the tournament theme and makes it a natural fixture for any One Piece collection. Collectors are drawn to it as a tangible link between the story's protagonist and the community events where the game was played.
