Magic Collector Boosters are booster packs targeted at collectors. Unlike Draft Boosters, which optimize the Draft experience with a lot of repetition and a huge number of commons, Collector Boosters are maximized for more diversity in content, with more rares, foils, extended art, borderless planeswalkers and showcase cards.
Each Collector Booster Box Contains 12 Collector Booster Packs
