The DON!! card is a recurring mechanic in the One Piece Trading Card Game, introduced to give players a resource that powers attacks and abilities, and its artwork has become one of the more collected aspects of the game. Double Pack sets, released by Bandai as a format pairing two packs of cards together, have drawn steady interest from collectors and players alike for offering broad coverage of the game's characters and themes. Volume 12 sits within the later years of the game's expanding catalogue, a period when alternate art treatments became a central draw for those building personal collections. This alternate art version features Rocks D. Xebec, the legendary pirate captain whose storied past looms large over the One Piece narrative. Collectors seek it for the chance to own a dramatic, character-focused rendering of a figure central to the story's lore, presented in a style distinct from the standard printing. Its unnumbered designation adds to its appeal among those who enjoy the hunt for special variants.
