Pauper

In this Magic format, all cards must have been printed at common rarity in a Magic set or product. Common promo cards are only legal if the card meets that qualification. If a common version of a particular card was ever released in Magic, any version of that card is legal in this format. Other than that, the usual rules for constructed decks apply: Minimum of 60 cards in the main deck (There is no maximum size for main decks) Up to 15 cards in your sideboard, if used No more than 4 of any individual card in the main deck and sideboard combined (with the exception of basic lands)
