Your very first chance to play with the cards from a brand-new set.

Prerelease events are casual Sealed events that provide you with the first chance to play a new set by building a 40-card deck out of a “prerelease kit.” These products contain six draft booster packs, a prerelease promo foil of any rare or mythic rare in the set, and a special spindown life counter. After you've built your deck, the rest of your cards count as your sideboard as you play your matches.
