MTG Booster Pack : Mystery Booster Convention Edition (MB1)

Mystery Booster is a set designed for Chaos Draft (where you pick boosters at random to draft from). You can play it many times and never have the same experience as there are cards from over FORTY sets in Mystery Booster. 

Mystery Booster cards are not Standard legal (unless you get a card that is already printed in a Standard legal set).

Convention Edition

Mystery Boosters contain 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.
