The most valuable cards in Digimon booster boxes are typically rare, secret rares, and alternate art cards. These include powerful Digimon with game-changing abilities, like Omnimon, Agumon, and Gabumon variants. Additionally, cards from popular archetypes or sets like "Xros Encounter" and "Across Time" often hold a higher value. Collectors and competitive players seek these cards for utility in decks or increasing rarity and potential market value.
