Flip a coin. If heads, you may attach up to 2 Grass Energy cards from your hand to Erika's Venusaur.

Gym Challenge is a set in the Gym series. It was released on 16 October 2000. The printed size is 132, and the checklist is the same length. Erika's Venusaur is 4/132, in position 4 of 132 on this checklist. Before it is 3 Brock's Ninetales, and after it is 5 Giovanni's Gyarados. The listed rarity is Rare Holo.
Erika's Venusaur is a Stage 2 Grass Pokémon with 90 HP. The card lists level 45. In the Pokédex this is Venusaur (#003), generation 1 (Kanto). The card says it evolves from Erika's Ivysaur. In this catalog that name is Ivysaur (#002).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Venusaur (#003) has 46 other cards in the catalog. Those other cards are in 27 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Venusaur 15/102 in Base (1999). That card is named Venusaur, while this one is Erika's Venusaur. That card lists 100 HP, and this one lists 90 HP. Both list the rarity Rare Holo. Mitsuhiro Arita illustrated that card, and Ken Sugimori illustrated this one. 46 other cards of Venusaur list a different HP.
The attack Growth lists no damage number. The cost is Grass. Flip a coin. If heads, you may attach up to 2 Grass Energy cards from your hand to Erika's Venusaur. Wide Solarbeam is another attack lists 20 damage. The cost is Grass, Grass, Grass, Grass. If your opponent has any Benched Pokémon, choose 2 of them (or 1 if he or she only has 1). This attack does 20 damage to each of them. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Fire ×2. Retreat cost is 2.
I keep a set binder for Gym Challenge, meant to hold every card of that set. This card is one slot in the Gym Challenge set binder. A generation binder holds one card of each species. Venusaur can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Kanto starters, without Charizard, Kanto Gym Leaders and their Pokémon, and Erika and her Pokémon. I still need this card.
