Circle of Protection: Red

Circle of Protection: Red debuted in the Alpha set of Magic: The Gathering in 1993, designed by Richard Garfield as part of a cycle of enchantments intended to provide players with specific defenses against each of the game's five colors. The card functions as a reactive tool, allowing a player to spend mana to prevent damage from red sources, a mechanic that highlights the game's foundational color pie philosophy where different colors maintain distinct strengths and weaknesses.

The Ninth Edition printing features artwork by Christopher Rush, a legendary illustrator in the game's early history known for his distinct, expressive style. By the time this version was released in 2005, the artwork had become a classic representative of the series' aesthetic. The card was well-received by players of the era as a reliable, repeatable sideboard option in constructed formats, valued for its ability to neutralize aggressive red-based strategies through a persistent and predictable defensive effect.
