COLLECTOR'S BREAKDOWN: BROCK'S GEODUDE - GYM HEROES (UNCOMMON) [38/132]

An Uncommon Pokémon card from the Gym Heroes expansion, featuring Brock’s signature Rock-type Geodude. The artwork by Atsuko Nishida depicts a determined Geodude against a blurred rocky outcrop, highlighting the character's rugged nature. The card features two moves: Tackle and Lucky Shot, the latter requiring a coin flip for strategic benched damage. This specific example is encapsulated in a Pi Grading (P1) slab, awarded a '10 Pristine' status, which is the highest tier for this third-party grading service.
