If you're going to draft with friends to build a sealed deck for battle, you'll want to look for Draft Boosters. Each ONE Draft Booster contains 15 cards and one token/ad card, including one card with a rarity of rare or higher and 3 uncommons, 10 commons, and 1 basic land. (A traditional foil borderless mythic rare planeswalker can be found in less than 1% of ONE Draft Boosters. A traditional foil card of any rarity replaces a common in 33% of ONE Draft Boosters.)
