To effectively sort and manage your booster box spoils, start by organizing cards by rarity: mythic, rare, uncommon, and common. Next, sort by color or mana type. Use labeled dividers and storage boxes to keep them orderly. For trading or selling, keep high-value cards in protective sleeves and a secure binder. Regularly review and update your collection to maintain organization. This method is useful for a Magic: The Gathering booster box, ensuring you can quickly find cards for deck-building or trading with fellow players.
