Blister packs are larger packages that typically contain one to three booster packs, a promotional card, a coin token, or other collectable items. The promotional card in a blister pack is often an exclusive holo or reverse holo design only available in that particular blister pack.

The Collector Booster is aimed at players who value serious collecting. Designed to be the best value if you're prioritizing collecting hard-to-find and exclusive cards - collectors can look forward to more foil cards and special treatment cards like the extended-art versions.
Each booster contains 15 Magic: The Gathering cards
