Before bundles were invented, people could only carry two things at once. Wanted to carry three things? Get a third arm, buddy. With WotC's patented Bundle Technology, you'll be able to carry way more than two things. Specifically, each bundle contains:
10 Core Set 2021 Draft Booster packs 20 basic lands 20 foil basic lands 1 alternate-art foil pack leader 1 oversized 20-sided die That's 52 things, which is significantly more than two.
