If your opponent has any Benched Pokémon, he or she chooses 1 of them and switches it with the Defending Pokémon. (Do the damage before switching the Pokémon.)

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. Butterfree is 33/64, in position 33 of 64 on this checklist. Before it is 32 Wigglytuff, and after it is 34 Dodrio. The listed rarity is Uncommon.
Butterfree is a Stage 2 Grass Pokémon with 70 HP. The card lists level 28. In the Pokédex this is Butterfree (#012), generation 1 (Kanto). The card says it evolves from Metapod. In this catalog that name is Metapod (#011).
Kagemaru Himeno illustrated this card. The same name is on 656 other cards in the catalog.
Butterfree (#012) has 24 other cards in the catalog. Those other cards are in 20 sets. The other printings with a release date run from 2000 to 2025. The earliest other card is Butterfree 34/130 in Base Set 2 (2000). Both list 70 HP. Both list the rarity Uncommon. 22 other cards of Butterfree list a different HP.
The attack Whirlwind lists 20 damage. The cost is Colorless, Colorless. If your opponent has any Benched Pokémon, he or she chooses 1 of them and switches it with the Defending Pokémon. (Do the damage before switching the Pokémon.) Mega Drain is another attack lists 40 damage. The cost is Grass, Grass, Grass, Grass. Remove a number of damage counters from Butterfree equal to half the damage done to the Defending Pokémon (after applying Weakness and Resistance) (rounded up to the nearest 10). Weakness is Fire ×2. Resistance is Fighting -30. The flavor text reads "In battle, it flaps its wings at high speed to release highly toxic dust into the air."
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. Butterfree can fill a slot in Generation 1 binder (Kanto). I still need this card.
