AttackCounter
If an attack damages Wobbuffet during your opponent's next turn (even if Wobbuffet is Knocked Out), flip a coin. If heads, Wobbuffet attacks the Defending Pokémon for an equal amount of damage.

Neo Discovery is a set in the Neo series. It was released on 1 June 2001. The printed size is 75, and the checklist is the same length. Wobbuffet is 16/75, in position 16 of 75 on this checklist. Before it is 15 Ursaring, and after it is 17 Yanma. The listed rarity is Rare Holo.
Wobbuffet is a Basic Psychic Pokémon with 90 HP. The card lists level 46. In the Pokédex this is Wobbuffet (#202), generation 2 (Johto).
Hironobu Yoshida illustrated this card. The same name is on 38 other cards in the catalog.
Wobbuffet (#202) has 22 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 2001 to 2025. The earliest other card is Wobbuffet 35/75 in Neo Discovery (2001). Both list 90 HP. The rarity there is Rare, and here it is Rare Holo. 18 other cards of Wobbuffet list a different HP.
The attack Counter lists no damage number. The cost is Psychic. If an attack damages Wobbuffet during your opponent's next turn (even if Wobbuffet is Knocked Out), flip a coin. If heads, Wobbuffet attacks the Defending Pokémon for an equal amount of damage. Weakness is Psychic ×2. Retreat cost is 3. The flavor text reads "To keep its pitch-black tail hidden, it lives quietly in the darkness. It is never first to attack."
I keep a set binder for Neo Discovery, meant to hold every card of that set. This card is one slot in the Neo Discovery set binder. A generation binder holds one card of each species. Wobbuffet can fill a slot in Generation 2 binder (Johto). I still need this card.
