Dugtrio is Pokédex #051, generation 1 (Kanto). Dark Dugtrio is a Stage 1 Fighting Pokémon with 50 HP. The card lists level 18. The card says it evolves from Diglett. In this catalog that name is Diglett (#050).
Dark Dugtrio sits at 6/82 in Team Rocket, position 6 of 83. Before it is 5 Dark Dragonite, and after it is 7 Dark Golbat. 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 Holo.
Sinkhole is listed as Pokémon Power. Whenever your opponent's Active Pokémon retreats, your opponent flips a coin. If tails, this power does 20 damage to that Pokémon. (Don't apply Weakness and Resistance.) This power stops working while Dark Dugtrio is Asleep, Confused, or Paralyzed. The attack Knock Down lists 20+ damage. The cost is Fighting, Fighting. Your opponent flips a coin. If tails, this attack does 20 damage plus 20 more damage; if heads, this attack does 20 damage. Weakness is Grass ×2. Resistance is Lightning -30. Retreat cost is 2. The flavor text reads "Digs large sinkholes in the ground and tries to trap its enemies in them."
Dugtrio (#051) has 30 other cards in the catalog. Those other cards are in 26 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Dugtrio 19/102 in Base (1999). That card is named Dugtrio, while this one is Dark Dugtrio. That card lists 70 HP, and this one lists 50 HP. The rarity there is Rare, and here it is Rare Holo. Keiji Kinebuchi illustrated that card, and Kagemaru Himeno illustrated this one. 29 other cards of Dugtrio list a different HP.
The illustrator line reads Kagemaru Himeno. I count 656 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. Dugtrio 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.
