Powerful Baseball

Powerful Baseball was a collectible card game released by Konami in Japan in July 2006, tied to the publisher's long-running Jikkyou Powerful Pro Yakyuu video game franchise. The set arrived after Konami's Prime Nine line concluded in 2005 and ran alongside their Baseball Heroes series, representing one chapter in Konami's roughly two-decade involvement with NPB-licensed trading cards. Cards featured Nippon Professional Baseball players with statistics and player imagery consistent with the Power Pros house art style. Whether the set incorporated a full standalone game system or functioned primarily as a collectible companion to the arcade and console games remains uncertain in collector records. The line was sold through hobby shops and convenience outlets across Japan. Detailed set lists and a precise card count for this specific release have not been widely catalogued in English-language collector resources, placing it firmly among the more elusive entries in Konami's baseball card catalog.
