Magic 2011 was released on July 16, 2010. It was the twelfth core set for Magic: The Gathering. As its predecessor, Magic 2010, the set has new cards in it, but this time 110 new cards.
Magic 2011 contains the keyword scry. This marks the first time that a mechanic from an expert level set has been printed in a core set, without making that mechanic evergreen, or permanently available for use in all future sets. Also, this set introduced the concept of "planeswalker signature cards": cards of lesser rarities that are tied directly to the central planeswalker characters of the set (ex. "Ajani's Pridemate" and "Ajani's Mantra" were included as a reference to the planeswalker "Ajani Goldmane"). These cards were made to make the identity of the planeswalkers more accessible to players, as the planeswalker cards themselves are only available in mythic rarities.
