Sealed Deck:
You build a new deck from six unopened booster packs. You are given time to open and build your decks. You may add as many basic lands as you’d like, even if they weren’t in the booster packs you opened. These games are 1v1 and can be played as best of one or best of three. This is the typical format for pre-release.
