Heroes of the Realm

Heroes of the Realm is a custom made series of black-bordered Magic: The Gathering celebration cards, recognizable by a special "Heroes of the Realm" card back.

Description
These cards are specifically created for Wizards of the Coast in very limited numbers, and handed out by the execs to some of their employees as a token of appreciation. Each card includes the name of the employee who receives the card in the right bottom corner. Since these cards don't have the regular card back, the cards aren't legal in any format.

They exist also as oversized cards but with no name of the recipient. An oversized card with all the names of the rewarded team hangs in the Hall of Heroes in the Wizards of the Coast Headquarters.

Mark Rosewater notes that these don't go through the normal design processes, so they aren't always representative of what R&D might actually do on a printed card. The cards aren't designed to be played. They're designed to be read. The Wizards of the Coast executive team chooses the winners and the winners design the cards (sometimes, but not always, with a little help from R&D).
