We are mere hours away from the answer to one of WOTC biggest secrets of the year, what is in the Mystery booster pack being debuted at Magic Fest Richmond?
(What's in the booster pack?)
Not much is know about the brand new boosters but from what info has been disseminated we have been led to believe the cards will be draftable but not standard legal. There is rumored to be a a convention version and a retail version but there has not been information given about retail sales.
Guesses about what is actually in the packs can be made below in the comments!
