Beginning August 20, limited quantities of Mystery Booster: Convention Edition will be available at WPN stores, with in-store play events available where possible, making for an exclusive experience that can be shared between players around the world.

But what is Mystery Booster? It's an awesome experience with the feel of a "Chaos Draft" that uses multiple Magic Draft Boosters from different releases but bundles the cards and variety you'd experience into one amazing package. The set itself contains a whopping 1,670 reprints from across the game's history, plus 121 copies of something new and surprising—R&D Playtest cards you won't find anywhere outside of Mystery Booster: Convention Edition. There are so many cards packed into the possibilities, you could fill an entire eight-person draft and not see the same card twice.

Cards in Mystery Booster have the original set symbols and numbering of one of their printings. The only difference is a Planeswalker symbol in the lower left corner, like what you find on cards from The List in Set Boosters.

Each Mystery Booster: Convention Edition booster pack contains fifteen cards: fourteen from the gigantically awesome main set, and one from that "something new and surprising" group of R&D Playtest cards.
