Provenance

Where it came from

The Agent of Treachery card was produced for the Avatar: The Last Airbender Eternal expansion, a set designed to translate the complex political and elemental landscapes of the series into a functional trading card game format. It was created as a mythic rarity creature, intended to represent the high-stakes manipulation and strategic subversion characteristic of the series' antagonists.

The illustration was handled by an in-house team at Viacom, reflecting the standardized aesthetic established for the Eternal game line. By focusing on the concept of forced allegiance and tactical shifting, the design team aimed to provide players with a high-impact card that disrupted board states, aligning the mechanical identity of the creature with the thematic essence of the show's most deceptive figures.
