Koga’s Ditto is a holographic Pokémon TCG trading card from the 2000 Gym Challenge expansion, illustrated by Ken Sugimori. The artwork shows Ditto surrounded by a pink-and-purple cosmic swirl accented by a classic holofoil sparkle pattern, which enhances its nostalgic appeal. Numbered 10/132 with a star rarity symbol, this rare Gym Leader–themed card celebrates Koga’s Poison Gym and holds special value for fans of the early Pokémon TCG era. While its “Giant Growth” coin-flip attack is a simple effect, collectors prize the vintage art and holo design that epitomize the classic Pokémon TCG style.
