This Pokémon takes 30 less damage from attacks (after applying Weakness and Resistance).

Battle Styles is a set in the Sword & Shield series. It was released on March 19, 2021. The printed size is 163. This checklist is longer, at 183 cards. Marowak is 70/163, in position 70 of 183 on this checklist. Before it is 69 Cubone, and after it is 71 Gligar. The listed rarity is Rare.
Marowak is a Stage 1 Fighting Pokémon with 110 HP. In the Pokédex this is Marowak (#105), generation 1 (Kanto). The card says it evolves from Cubone. In this catalog that name is Cubone (#104).
Narumi Sato illustrated this card. The same name is on 44 other cards in the catalog.
Marowak (#105) has 21 other cards in the catalog. Those other cards are in 20 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Marowak 39/64 in Jungle (1999). That card lists 60 HP, and this one lists 110 HP. The rarity there is Uncommon, and here it is Rare. Mitsuhiro Arita illustrated that card, and Narumi Sato illustrated this one. Retreat cost there is 1, and here it is 2. 20 other cards of Marowak list a different HP.
Battle Armor is listed as Ability. This Pokémon takes 30 less damage from attacks (after applying Weakness and Resistance). The attack Bonemerang lists 90× damage. The cost is Fighting, Colorless. Flip 2 coins. This attack does 90 damage for each heads. Weakness is Grass ×2. Retreat cost is 2. The flavor text reads "They thump their bones rhythmically to communicate among themselves. There are nearly 50 different rhythmic patterns." The regulation mark is E.
I keep a set binder for Battle Styles, meant to hold every card of that set. This card is one slot in the Battle Styles set binder. A generation binder holds one card of each species. Marowak can fill a slot in Generation 1 binder (Kanto). I still need this card.
