Corrupted Conscience

Corrupted Conscience was released in 2011 as part of the Mirrodin Besieged set for the Magic: The Gathering trading card game. It was designed to function within the set's central narrative theme, which depicted the ongoing conflict between the native inhabitants of the metal world of Mirrodin and the invasive, metallic infection of the Phyrexians. As a blue enchantment, the card represented the psychological and physical assimilation of a creature by the Phyrexians, providing players with the ability to gain control of an opponent's unit while granting it the lethal 'infect' keyword.

The card’s visual identity was brought to life by illustrator Jason Chan, who crafted an image that perfectly captures the unsettling nature of Phyrexian conversion. His depiction of a knight being consumed by glistening oil and wires aligns with the set's dark, biomechanical aesthetic. Upon its release, the card became a notable inclusion in limited play environments, valued by players for its dual utility as both a theft effect and a win condition, cementing its place as a quintessential example of the set's infect-based mechanics.
