Mystery Boosteris 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.
You might have seen people celebrating this weird and wonderful Draft format over the weekend at MagicFest Richmond. It's pretty wild. I'm sure you have questions. So let's get to some answers.
The set itself contains a whopping 1,694 reprints from all throughout the game's history (see below for the full list), plus 121 copies of something new and surprising. You could fill an entire eight-person draft and not see the same card twice.
Cards in Mystery Booster will have the original set symbols and numbering of one of their printings. The only difference? A little Planeswalker symbol in the lower left corner. Like this:
16 Cards per Booster Pack 24 Boosters per Booster Box
