Weezing is Pokédex #110, generation 1 (Kanto). Dark Weezing is a Stage 1 Grass Pokémon with 60 HP. The card lists level 24. The card says it evolves from Koffing. In this catalog that name is Koffing (#109).
Dark Weezing sits at 31/82 in Team Rocket, position 31 of 83. Before it is 30 Dark Vileplume, and after it is 32 Dark Charmeleon. The set belongs to the Base series. It was released on April 24, 2000. The printed size is 82. This checklist is longer, at 83 cards. The listed rarity is Rare.
The attack Mass Explosion lists 20× damage. The cost is Grass, Colorless. Does 20 damage times the total number of Koffings, Weezings, and Dark Weezings in play (Apply Weakness and Resistance.). Then, this attack does 20 damage to each Koffing, Weezing, and Dark Weezing (even your own). Don't apply Weakness and Resistance. Stun Gas is another attack lists 20 damage. The cost is Grass, Grass, Grass. Flip a coin. If heads, the Defending Pokémon is now Poisoned; if tails, the Defending Pokémon is now Paralyzed. Weakness is Psychic ×2. Retreat cost is 1. The flavor text reads "Researchers have observed these Pokémon reproducing in industrial waste sites."
Weezing (#110) has 28 other cards in the catalog. Those other cards are in 25 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Weezing 45/62 in Fossil (1999). That card is named Weezing, while this one is Dark Weezing. Both list 60 HP. The rarity there is Uncommon, and here it is Rare. Mitsuhiro Arita illustrated that card, and Shin-ichi Yoshida illustrated this one. 26 other cards of Weezing list a different HP.
The illustrator line reads Shin-ichi Yoshida. I count 50 other cards in the catalog with that illustrator.
Team Rocket set binder is where a full Team Rocket set goes. This card fills one slot there. A generation binder holds one card of each species. Weezing can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Team Rocket cards. I still need this card.
