Sparkling Crystal is an Ace Spec Trainer (Pokémon Tool) card from the Japanese SV8a: Terastal Fest EX set (2024) of the Pokémon TCG, celebrating Scarlet & Violet’s new Terastal phenomenon. Illustrator Toyste Beach depicts a luminous blue crystal cluster against a vivid mirror holofoil Poké Ball background, highlighting the card’s rare foil design. In play, Sparkling Crystal lowers the energy cost of attacks for any Terastallized Pokémon, reinforcing the set’s Tera-mechanics focus. Collectors prize this Japanese trading card for its striking artwork and rarity; it first appeared in the 2024 Stellar Crown expansion, adding nostalgic value to this special reprint.
