AttackPoisonpowder
The Defending Pokémon is now Poisoned.

Jungle is a set in the Base series. It was released on June 16, 1999. The printed size is 64, and the checklist is the same length. Gloom is 37/64, in position 37 of 64 on this checklist. Before it is 36 Fearow, and after it is 38 Lickitung. The listed rarity is Uncommon.
Gloom is a Stage 1 Grass Pokémon with 60 HP. The card lists level 35. In the Pokédex this is Gloom (#044), generation 1 (Kanto). The card says it evolves from Oddish. In this catalog that name is Oddish (#043). The card lists Vileplume, Vileplume (#045) and Bellossom, Bellossom (#182) under evolves to.
Keiji Kinebuchi illustrated this card. The same name is on 212 other cards in the catalog.
Gloom (#044) has 25 other cards in the catalog. Those other cards are in 22 sets. The other printings with a release date run from 2000 to 2026. The earliest other card is Dark Gloom 36/82 in Team Rocket (2000). That card is named Dark Gloom, while this one is Gloom. That card lists 50 HP, and this one lists 60 HP. Both list the rarity Uncommon. Kagemaru Himeno illustrated that card, and Keiji Kinebuchi illustrated this one. Retreat cost there is 2, and here it is 1. 23 other cards of Gloom list a different HP.
The attack Poisonpowder lists no damage number. The cost is Grass. The Defending Pokémon is now Poisoned. Foul Odor is another attack lists 20 damage. The cost is Grass, Grass. Both the Defending Pokémon and Gloom are now Confused (after doing damage). Weakness is Fire ×2. Retreat cost is 1. The flavor text reads "The fluid that oozes from its mouth isn't drool; it is a nectar that is used to attract prey."
I keep a set binder for Jungle, meant to hold every card of that set. This card is one slot in the Jungle set binder. A generation binder holds one card of each species. Gloom can fill a slot in Generation 1 binder (Kanto). I still need this card.
