Mystery Booster Box - Retail ExclusiveAvailable Friday, March 13 2020
Mystery Booster is a booster pack release inspired by those Chaos, Cube, and off-format drafts. It is, in effect, a chaos draft in a pack. With some twists. The set itself contains a whopping 1,694 reprints from all throughout the game's history, plus 121 copies of something new and surprising.
You could fill an entire eight-person draft and not see the same card twice, making the Draft experience even more repeatable.
