Part of the 2021 Pokémon TCG Sword & Shield – Chilling Reign expansion, this Elite Trainer Box features line-art of Shadow Rider Calyrex and its ghostly steed on a purple icy backdrop. It includes eight Chilling Reign booster packs, 65 matching card sleeves featuring Shadow Rider Calyrex art, energy cards, damage dice, acrylic condition markers, a foil coin, and a code card – everything needed to jump into Pokémon Trading Card Game battles. The collector-friendly design highlights Shadow Rider Calyrex (the Psychic-type fusion of Calyrex and spectral horse Spectrier), which made its official Pokémon TCG debut in the Chilling Reign expansion. As a sealed set, it appeals both to players seeking new cards (including powerful Pokémon V and VMAX from Chilling Reign) and to collectors drawn by its exclusive artwork and Sword & Shield–era nostalgia.
