The SD Gundam CCG is a Carddass-format collectible card product published by Bandai in Japan in September 1998, featuring the super-deformed chibi aesthetic of the long-running SD Gundam spin-off franchise. Carddass was Bandai's proprietary card vending-machine and retail-card platform, which served as a home for dozens of anime and game properties throughout the 1990s and 2000s. SD Gundam Carddass sets from this period were sold in boxed lots and through arcade-style vending units, with complete sets documented across multiple collector volumes. The cards lean toward the collectible end of the spectrum, pairing character art with combat statistics, and are part of a broader continuum of Gundam Carddass products that predates the standalone Gundam War CCG launched by Bandai in February 1999. Print runs for specific 1998 volumes are not fully catalogued in English-language sources, and detailed rulebook documentation is limited outside Japan.
