The attack Group Attack lists 10× damage. The cost is Grass, Colorless. Does 10 damage times the number of Koga's Zubats you have in play. Before doing damage, you may search your deck for any number of Basic Pokémon named Koga's Zubat and put them onto your Bench.

Zubat (#041) has 27 other cards in the catalog. Those other cards are in 24 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Zubat 57/62 in Fossil (1999). That card is named Zubat, while this one is Koga's Zubat. Both list 40 HP. Both list the rarity Common. Kagemaru Himeno illustrated that card, and Ken Sugimori illustrated this one. 18 other cards of Zubat list a different HP.
The illustrator line reads Ken Sugimori. I count 1,112 other cards in the catalog with that illustrator.
Gym Challenge set binder is where a full Gym Challenge set goes. This card fills one slot there. A generation binder holds one card of each species. Zubat can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon and Kanto Gym Leaders and their Pokémon. I still need this card.
