Gym Heroes is a set in the Gym series. It was released on 14 August 2000. The printed size is 132, and the checklist is the same length. Erika's Exeggcute is 43/132, in position 43 of 132 on this checklist. Before it is 42 Erika's Dratini, and after it is 44 Erika's Exeggutor. The listed rarity is Uncommon.
Erika's Exeggcute is a Basic Grass Pokémon with 50 HP. The card lists level 15. In the Pokédex this is Exeggcute (#102), generation 1 (Kanto). The card lists Exeggutor, Exeggutor (#103) under evolves to.
Atsuko Nishida illustrated this card. The same name is on 408 other cards in the catalog.
Exeggcute (#102) has 33 other cards in the catalog. Those other cards are in 30 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Exeggcute 52/64 in Jungle (1999). That card is named Exeggcute, while this one is Erika's Exeggcute. Both list 50 HP. The rarity there is Common, and here it is Uncommon. Mitsuhiro Arita illustrated that card, and Atsuko Nishida illustrated this one. 18 other cards of Exeggcute list a different HP.
The attack Deflector lists no damage number. The cost is Psychic. During your opponent's next turn, whenever Erika's Exeggcute takes damage, divide that damage in half (rounded down to the nearest 10). (Any other effects still happen.) Egg Bomb is another attack lists 40 damage. The cost is Grass, Colorless. Flip a coin. If tails, this attack does nothing to the Defending Pokémon and Erika's Exeggcute does 20 damage to itself. Weakness is Fire ×2. Retreat cost is 1.
I keep a set binder for Gym Heroes, meant to hold every card of that set. This card is one slot in the Gym Heroes set binder. A generation binder holds one card of each species. Exeggcute can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Atsuko Nishida cards, early series, Kanto Gym Leaders and their Pokémon, and Erika and her Pokémon. I still need this card.
