AbilityMore Poison
Put 2 more damage counters on your opponent's Poisoned Pokémon during Pokémon Checkup.

Sword & Shield is a set in the Sword & Shield series. It was released on 7 February 2020. The printed size is 202. This checklist is longer, at 216 cards. Toxicroak is 124/202, in position 124 of 216 on this checklist. Before it is 123 Croagunk, and after it is 125 Nickit. The listed rarity is Rare Holo.
Toxicroak is a Stage 1 Darkness Pokémon with 110 HP. In the Pokédex this is Toxicroak (#454), generation 4 (Sinnoh). The card says it evolves from Croagunk. In this catalog that name is Croagunk (#453).
Ryuta Fuse illustrated this card. The same name is on 98 other cards in the catalog.
Toxicroak (#454) has 20 other cards in the catalog. Those other cards are in 18 sets. The other printings with a release date run from 2007 to 2025. The earliest other card is Toxicroak G DP41/56 in DP Black Star Promos (2007). That card is named Toxicroak G, while this one is Toxicroak. That card lists 90 HP, and this one lists 110 HP. The rarity there is Promo, and here it is Rare Holo. Ryota Saito illustrated that card, and Ryuta Fuse illustrated this one. Retreat cost there is 2, and here it is 1. 18 other cards of Toxicroak list a different HP.
More Poison is listed as Ability. Put 2 more damage counters on your opponent's Poisoned Pokémon during Pokémon Checkup. The attack Poison Claws lists 70 damage. The cost is Darkness, Colorless, Colorless. Flip a coin. If heads, your opponent's Active Pokémon is now Poisoned. Weakness is Fighting ×2. Retreat cost is 1. The flavor text reads "It bounces toward opponents and gouges them with poisonous claws. No more than a scratch is needed to knock out its adversaries." The regulation mark is D.
I keep a set binder for Sword & Shield, meant to hold every card of that set. This card is one slot in the Sword & Shield set binder. A generation binder holds one card of each species. Toxicroak can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
