In 2021 the **Pokémon TCG** Sword & Shield—***Chilling Reign*** booster box introduced a frosty expansion set focusing on Galarian Legendary Pokémon. The official sealed booster box art depicts **Ice Rider Calyrex** amid swirling frost and icy motifs, reflecting the expansion’s cold, mystical theme. As an official **trading card game** product, the sealed box contains 36 packs of Chilling Reign (each with 10 cards), including powerful Pokémon like **Ice Rider Calyrex VMAX** and the trio of Galarian **Articuno**, **Zapdos**, and **Moltres** appearing as holographic rare cards. Chilling Reign’s mix of potent Pokémon V/VMAX cards and vivid alternate-art holofoil designs adds nostalgic appeal and new deck-building strategies, making this booster box a compelling choice for collectors and competitive players alike.
