This sealed Lost Thunder booster box is part of the Pokémon TCG Sun & Moon series (released November 2018) and contains 36 English booster packs. The vibrant box and pack art feature Lugia and the Mythical Electric-type Pokémon Zeraora amid crackling thunderclouds, hinting at the set’s stormy theme. Each foil booster pack has 10 cards, offering players chances to pull powerful GX cards like Lugia-GX and Zeraora-GX as well as rare Prism Star trainers. Collectors love the bold, electrifying illustration and nostalgia of this late-series expansion, making it a sought-after set for both play and display.
