AttackHypnosis
The Defending Pokémon is now Asleep.

Base is a set in the Base series. It was released on January 9, 1999. The printed size is 102, and the checklist is the same length. Haunter is 29/102, in position 29 of 102 on this checklist. Before it is 28 Growlithe, and after it is 30 Ivysaur. The listed rarity is Uncommon.
Haunter is a Stage 1 Psychic Pokémon with 60 HP. The card lists level 22. In the Pokédex this is Haunter (#093), generation 1 (Kanto). The card says it evolves from Gastly. In this catalog that name is Gastly (#092). The card lists Gengar, Gengar (#094) under evolves to.
Keiji Kinebuchi illustrated this card. The same name is on 212 other cards in the catalog.
Haunter (#093) has 30 other cards in the catalog. Those other cards are in 28 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Haunter 6/62 in Fossil (1999). That card lists 50 HP, and this one lists 60 HP. The rarity there is Rare Holo, and here it is Uncommon. Ken Sugimori illustrated that card, and Keiji Kinebuchi illustrated this one. 29 other cards of Haunter list a different HP.
The attack Hypnosis lists no damage number. The cost is Psychic. The Defending Pokémon is now Asleep. Dream Eater is another attack lists 50 damage. The cost is Psychic, Psychic. You can't use this attack unless the Defending Pokémon is Asleep. Resistance is Fighting -30. Retreat cost is 1. The flavor text reads "Because of its ability to slip through block walls, it is said to be from another dimension."
I keep a set binder for Base, meant to hold every card of that set. This card is one slot in the Base set binder. A generation binder holds one card of each species. Haunter can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Gengar and the Gastly line. I still need this card.
