Set Boosters are the way to crack packs of a new set. Arranged by theme, and containing up to 4 rares or mythics, Set Boosters value to a deck builder is astronomically better than a draft booster. On average, we are seeing 50 rares per box in a set boosters, instead of 36 in a draft booster. With a foil in every pack, and a chance at a card from The List, this makes set boosters the most exciting way to open a new Magic set!
