Lost Thunder is a set in the Sun & Moon series. It was released on 2 November 2018. The printed size is 214. This checklist is longer, at 240 cards. Toxapex is 69/214, in position 69 of 240 on this checklist. Before it is 68 Mareanie, and after it is 70 Bruxish. The listed rarity is Rare.
Toxapex is a Stage 1 Water Pokémon with 120 HP. In the Pokédex this is Toxapex (#748), generation 7 (Alola). The card says it evolves from Mareanie. In this catalog that name is Mareanie (#747).
kirisAki illustrated this card. The same name is on 189 other cards in the catalog.
Toxapex (#748) has 7 other cards in the catalog. Those other cards are in 5 sets. The other printings with a release date run from 2017 to 2022. The earliest other card is Toxapex 63/149 in Sun & Moon (2017). That card lists 110 HP, and this one lists 120 HP. The rarity there is Rare Holo, and here it is Rare. Mitsuhiro Arita illustrated that card, and kirisAki illustrated this one. 6 other cards of Toxapex list a different HP.
The attack Poison Sting lists no damage number. The cost is Water. Your opponent's Active Pokémon is now Poisoned. Venom Fever is another attack lists 50× damage. The cost is Water, Water. If your opponent's Active Pokémon is Poisoned, this attack does 50 damage for each damage counter on that Pokémon. Weakness is Grass ×2. Retreat cost is 3. The flavor text reads "Those attacked by Toxapex's poison will suffer intense pain for three days and three nights. Post-recovery, there will be some aftereffects."
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. Toxapex can fill a slot in Generation 7 binder (Alola). I still need this card.
