The No.1 Trainer card released in the handbook.
The Pokémon Card Official Book 2000
is a handbook of the Pokémon Trading Card Game
released exclusively to Japan in 2000. It features full scale, full color images of every Pokemon card, including regular releases, promos, and tourney cards, up until the release of Neo Genesis
sets. Many exclusively released cards were printed in this book that are almost impossible to obtain, such as the No.1 Trainer (Secret Super Battle promo)
, one of the rarest cards in existence.
