The Defending Pokémon has no Abilities until the end of your next turn.

Arbok is Pokédex #024, generation 1 (Kanto). Arbok is a Stage 1 Psychic Pokémon with 90 HP. The card says it evolves from Ekans. In this catalog that name is Ekans (#023).
Arbok sits at 48/146 in XY, position 48 of 146. Before it is 47 Ekans, and after it is 49 Spoink. The set belongs to the XY series. It was released on February 5, 2014. The printed size is 146, and the checklist is the same length. The listed rarity is Rare.
The attack Gastro Acid lists 20 damage. The cost is Colorless. The Defending Pokémon has no Abilities until the end of your next turn. Poison Jab is another attack lists 50 damage. The cost is Psychic, Colorless, Colorless. Your opponent's Active Pokémon is now Poisoned. Weakness is Psychic ×2. Retreat cost is 1. The flavor text reads "The pattern on its belly appears to be a frightening face. Weak foes will flee just at the sight of the pattern."
Arbok (#024) has 19 other cards in the catalog. Those other cards are in 15 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Arbok 31/62 in Fossil (1999). That card lists 60 HP, and this one lists 90 HP. The rarity there is Uncommon, and here it is Rare. Ken Sugimori illustrated that card, and Naoki Saito illustrated this one. Retreat cost there is 2, and here it is 1. 17 other cards of Arbok list a different HP.
The illustrator line reads Naoki Saito. I count 270 other cards in the catalog with that illustrator.
XY set binder is where a full XY set goes. This card fills one slot there. A generation binder holds one card of each species. Arbok can fill a slot in Generation 1 binder (Kanto). I still need this card.
