Team Rocket is a set in the Base series. It was released on 24 April 2000. The printed size is 82. This checklist is longer, at 83 cards. Dark Weezing is 14/82, in position 14 of 83 on this checklist. Before it is 13 Dark Vileplume, and after it is 15 Here Comes Team Rocket!. The listed rarity is Rare Holo.
Dark Weezing is a Stage 1 Grass Pokémon with 60 HP. The card lists level 24. In the Pokédex this is Weezing (#110), generation 1 (Kanto). The card says it evolves from Koffing. In this catalog that name is Koffing (#109).
Shin-ichi Yoshida illustrated this card. The same name is on 50 other cards in the catalog.
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 Holo. Mitsuhiro Arita illustrated that card, and Shin-ichi Yoshida illustrated this one. 26 other cards of Weezing list a different HP.
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."
I keep a set binder for Team Rocket, meant to hold every card of that set. This card is one slot in the Team Rocket set binder. 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.
