The Defending Pokémon can't retreat during your opponent's next turn.

Burning Shadows is a set in the Sun & Moon series. It was released on August 5, 2017. The printed size is 147. This checklist is longer, at 177 cards. Eelektross is 46/147, in position 48 of 177 on this checklist. Before it is 45 Eelektrik, and after it is 47 Togedemaru. The listed rarity is Rare.
Eelektross is a Stage 2 Lightning Pokémon with 140 HP. In the Pokédex this is Eelektross (#604), generation 5 (Unova). The card says it evolves from Eelektrik. In this catalog that name is Eelektrik (#603).
hatachu illustrated this card. The same name is on 31 other cards in the catalog.
Eelektross (#604) has 14 other cards in the catalog. Those other cards are in 11 sets. The other printings with a release date run from 2011 to 2026. The earliest other card is Eelektross 41/101 in Noble Victories (2011). Both list 140 HP. The rarity there is Rare Holo, and here it is Rare. Masakazu Fukuda illustrated that card, and hatachu illustrated this one. 10 other cards of Eelektross list a different HP.
The attack Dark Clamp lists 50 damage. The cost is Lightning, Colorless. The Defending Pokémon can't retreat during your opponent's next turn. Vacuum Bolt is another attack lists 80+ damage. The cost is Lightning, Lightning, Colorless. You may do 80 more damage. If you do, this attack does 80 damage to 1 of your Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Fighting ×2. Resistance is Metal -20. Retreat cost is 3. The flavor text reads "With their sucker mouths, they suck in prey. Then they use their fangs to shock the prey with electricity."
I keep a set binder for Burning Shadows, meant to hold every card of that set. This card is one slot in the Burning Shadows set binder. A generation binder holds one card of each species. Eelektross can fill a slot in Generation 5 binder (Unova). I still need this card.
