The Magic: The Gathering 2013 Core Set, commonly referred to as Magic 2013 or M13, is a core set released July 13, 2012.
Magic 2013 contains 249 cards (101 Common, 60 Uncommon, 53 Rare, 15 Mythic, 20 Basic Lands), including randomly inserted premium versions of all cards. The returning mechanic for this Core Set was Exalted. Magic 2013 was the first Core Set to contain zero cards that had appeared in every core set from Alpha on (excluding the basic lands). It was also the first Core Set after Alpha to feature original art on (some of) the basic lands.
Magic 2013 is largely built around Nicol Bolas, Planeswalker, which became the first multicolored card to be included in a core set. The set also includes a cycle of Legendary creatures (only the second time a core set included Legendary creatures (the first was Tenth Edition) and a cycle of Planeswalkers. Ajani Goldmane and Liliana Vess received new cards. Magic 2013 is tightly incorporated into into the digital Duels of the Planeswalkers 2013 which contained a theme deck for each Planeswalker and Legendary creature, and featured those characters as opponents and Nicol Bolas as the final boss. Due to the close prospective release dates, "Duels 2013" was pushed as the introductory set, while Magic 2013 itself was to be the Magic "showcase", having many high-end, high-impact spells.
