Circle of Protection: Blue

Circle of Protection: Blue originated as part of the core gameplay mechanics in the earliest iterations of Magic: The Gathering. When the controversial Summer Magic set, internally referred to as Edgar, was produced in 1994 to correct printing errors found in the Revised Edition, this card was included as part of the standard white-bordered card list. It was designed to serve as a niche defensive enchantment, allowing players to pay mana to prevent damage from blue sources, reflecting the color-pie-based strategic counterplay intended by Richard Garfield.

The artwork for this particular iteration of the card utilizes the established illustrative style of the era, focusing on symbolic representations of magical barriers. Because the Summer Magic print run was intended for general distribution but was largely recalled due to quality control issues and misprints, it became one of the most sought-after rarities in the hobby. Collectors prize these cards not only for their mechanical role in the game's history but for the specific, short-lived production context that differentiates them from their more common counterparts.
