A Build & Battle Box is the prerelease kit for Chilling Reign: a 40-card ready-to-play Evolution pack built around featured cards, plus 4 booster packs from the set — enough to build and play a deck on the spot. The larger Build & Battle Stadium packages two of these kits with extra booster packs for head-to-head play.
Standard contents; exact pack counts can vary by release.
Chilling Reign built around the Calyrex legends and their Ice and Shadow Rider forms, and introduced the alternate-art trainer cards that became the era's most sought-after pulls.
