AttackRetaliate
If any of your Pokémon were Knocked Out by damage from an opponent's attack during their last turn, this attack does 90 more damage.

Lost Thunder is a set in the Sun & Moon series. It was released on November 2, 2018. The printed size is 214. This checklist is longer, at 240 cards. Umbreon is 120/214, in position 120 of 240 on this checklist. Before it is 119 Alolan Persian, and after it is 121 Tyranitar-GX. The listed rarity is Rare.
Umbreon is a Stage 1 Darkness Pokémon with 110 HP. In the Pokédex this is Umbreon (#197), generation 2 (Johto). The card says it evolves from Eevee. In this catalog that name is Eevee (#133).
Ryota Murayama illustrated this card. The same name is on 55 other cards in the catalog.
Umbreon (#197) has 45 other cards in the catalog. Those other cards are in 26 sets. The other printings with a release date run from 2001 to 2026. The earliest other card is Umbreon 13/75 in Neo Discovery (2001). That card lists 80 HP, and this one lists 110 HP. The rarity there is Rare Holo, and here it is Rare. Kimiya Masago illustrated that card, and Ryota Murayama illustrated this one. 40 other cards of Umbreon list a different HP.
The attack Retaliate lists 30+ damage. The cost is Darkness. If any of your Pokémon were Knocked Out by damage from an opponent's attack during their last turn, this attack does 90 more damage. Dark Cutter is another attack lists 60 damage. The cost is Darkness, Colorless. Weakness is Fighting ×2. Resistance is Psychic -20. Retreat cost is 1. The flavor text reads "With its black fur, it blends into the darkness. It bides its time, and when prey appears, this Pokémon goes for its threat, and then eats it."
I keep a set binder for Lost Thunder, meant to hold every card of that set. This card is one slot in the Lost Thunder set binder. A generation binder holds one card of each species. Umbreon can fill a slot in Generation 2 binder (Johto). Themed lists that include this exact card are Eevee and the Eeveelutions. I still need this card.
