Provenance

Where it came from

The Boros Signet was introduced in the 2005 Ravnica: City of Guilds expansion, designed to support the set's dual-color guild mechanics. As a mana-fixing artifact, it allowed players to convert colorless mana into the red and white colors associated with the Boros Legion, reflecting the militaristic efficiency and rapid expansion of the guild within the Ravnica plane.

The card features artwork by Greg Staples, who utilized a bold, high-contrast aesthetic to emphasize the rigid, orderly nature of the Boros guild. The design was received favorably by the Magic: The Gathering community, becoming a staple in Commander and other formats for its reliable efficiency and clear thematic alignment with its color identity.
