Once during your turn (before your attack), you may flip a coin. If heads, remove 1 damage counter from 1 of your Pokémon. This power can't be used if Vileplume is Asleep, Confused, or Paralyzed.

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. Vileplume is 15/64, in position 15 of 64 on this checklist. Before it is 14 Victreebel, and after it is 16 Wigglytuff. The listed rarity is Rare Holo.
Vileplume is a Stage 2 Grass Pokémon with 80 HP. The card lists level 35. In the Pokédex this is Vileplume (#045), generation 1 (Kanto). The card says it evolves from Gloom. In this catalog that name is Gloom (#044).
Keiji Kinebuchi illustrated this card. The same name is on 212 other cards in the catalog.
Vileplume (#045) has 25 other cards in the catalog. Those other cards are in 20 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Vileplume 31/64 in Jungle (1999). Both list 80 HP. The rarity there is Rare, and here it is Rare Holo. 23 other cards of Vileplume list a different HP.
Heal is listed as Pokémon Power. Once during your turn (before your attack), you may flip a coin. If heads, remove 1 damage counter from 1 of your Pokémon. This power can't be used if Vileplume is Asleep, Confused, or Paralyzed. The attack Petal Dance lists 40× damage. The cost is Grass, Grass, Grass. Flip 3 coins. This attack does 40 damage times the number of heads. Vileplume is now Confused (after doing damage). Weakness is Fire ×2. Retreat cost is 2. The flavor text reads "The larger its petals, the more toxic pollen it contains. Its big head is heavy and hard to hold up."
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. Vileplume can fill a slot in Generation 1 binder (Kanto). I still need this card.
