Skygalleon is a Japanese collectible card game developed and published by Silver Blitz, a studio based in Japan best known for producing the Lycee Trading Card Game. Released in February 2013, Skygalleon is distinct from the Lycee line but shares Silver Blitz's characteristic approach of featuring original fantasy-themed characters with detailed illustrative art. The game launched with its 1.0 set in February 2013 and expanded through a 2.0 set in May 2013 and a 3.0 set in September 2013, suggesting a rapid expansion schedule during its active period. Cards from the series surface occasionally on Japanese secondary markets such as Suruga-ya, with individual cards typically priced at low collector values. Precise rules documentation and card counts are not widely available in English-language sources. The game circulated exclusively in the Japanese domestic market. Surviving physical cards confirm its existence, but detailed play documentation is scarce, which is exactly why it sits in the uncharted archive.
