Koga, Sabrina, Blaine, and Giovanni are four Gym Challenge theme decks. Each 60-card pre-constructed deck comes packaged with a holographic Alakazam coin, a Gym Challenge card checklist, a (then-current) Pokémon TCG rule book, and several cardboard damage counters. They were originally released in stores with Gym Challenge on October 16th, 2000 for $9.99 each, but are now long out of print.
The theme decks feature the last four Kanto Gym Leaders players can face in Pokémon Red and Blue, as does most of the main set. In Japan, two theme decks featuring Sabrina and Blaine were also released, both using the same holos as their English counterparts below but with otherwise different contents. No decks were released for Koga or Giovanni, however.
Koga Theme Deck
“Koga” features a holographic Koga’s Beedrill card and primarily focuses on Grass-type Pokémon, as Koga uses Poison-types in the Gameboy games. For more information on this deck, jump to the top of this page.
Sabrina Theme Deck
“Sabrina” features a holographic Sabrina’s Alakazam card and primarily focuses on Psychic-type Pokémon, her speciality in the Gameboy games. For more information on this deck, jump to the top of this page.
Blaine Theme Deck
“Blaine” features a holographic Blaine’s Arcanine card and primarily focuses on Fire-type Pokémon, Blaine’s specialty in the Gameboy games. For more information on this deck, jump to the top of this page.
Giovanni Theme Deck
“Giovanni” features a holographic Giovanni’s Persian card and primarily focuses on Fighting and Grass-type Pokémon, since Giovanni uses Ground-type Pokemon in the Gameboy games. His signature Pokémon is Persian, which he owns in Pokémon Yellow and Stadium and is often seen with in the animé. For more information on this deck, jump to the top of this page.
“Koga,” “Sabrina,” “Blaine,” and “Giovanni” each come with a purple, holographic Alakazam coin that cannot be found in any other Pokémon TCG product. The coin obviously features Sabrina’s Alakazam.
