Yveltal is Pokédex #717, generation 6 (Kalos). Yveltal-GX is a Basic GX Darkness Pokémon with 180 HP.
Yveltal-GX sits at 79/131 in Forbidden Light, position 80 of 150. Before it is 78 Pangoro, and after it is 80 Guzzlord. The set belongs to the Sun & Moon series. It was released on 4 May 2018. The printed size is 131. This checklist is longer, at 150 cards. The listed rarity is Rare Holo GX.
The attack Absorb Vitality lists 20 damage. The cost is Darkness. Heal from this Pokémon the same amount of damage you did to your opponent's Active Pokémon. Sonic Evil is another attack lists 100 damage. The cost is Colorless, Colorless, Colorless. This attack's damage isn't affected by Weakness or Resistance. Doom Count-GX is another attack lists no damage number. The cost is Darkness. If your opponent's Active Pokémon has exactly 4 damage counters on it, that Pokémon is Knocked Out. (You can't use more than 1 GX attack in a game.) Weakness is Lightning ×2. Resistance is Fighting -20. Retreat cost is 2. The card text says: Pokémon-GX rule: When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
Yveltal (#717) has 27 other cards in the catalog. Those other cards are in 17 sets. The other printings with a release date run from 2013 to 2026. The earliest other card is Yveltal XY06/211 in XY Black Star Promos (2013). That card is named Yveltal, while this one is Yveltal-GX. That card lists 130 HP, and this one lists 180 HP. The rarity there is Promo, and here it is Rare Holo GX. 25 other cards of Yveltal list a different HP.
The illustrator line reads 5ban Graphics. I count 1,629 other cards in the catalog with that illustrator.
Forbidden Light set binder is where a full Forbidden Light set goes. This card fills one slot there. A generation binder holds one card of each species. Yveltal can fill a slot in Generation 6 binder (Kalos). I still need this card.
