This Japanese Pokémon TCG trading card is a reverse-holo “Master Ball Mirror” variant of Brute Bonnet from the SV8a Terastal Fest EX set (2024, #099/187). The Anesaki Dynamic illustration shows Brute Bonnet unleashing its Rampaging Hammer attack in a vivid ancient-forest scene, all enhanced by a cracked-ice holofoil background and a subtle Master Ball emblem on the lower foil. Collectors will appreciate the Ancient (古代) trait symbol – marking it as a Paradox Pokémon – along with the card’s vibrant reverse-holo foil effect, making this Japanese card a standout collectible. Originally printed in the Ancient Roar (SV4K) expansion, Brute Bonnet’s Toxic Powder Ability (poisoning both Active Pokémon) gives this foil reprint added playability in Poison-themed decks, blending competitive utility with collectible appeal.
