Provenance

Where it came from

The Opaline Unicorn was released in 2013 as part of the Theros expansion for Magic: The Gathering. Drawing heavy inspiration from Greek mythology, the set focused on themes of gods, heroes, and enchantments, with the Unicorn serving as a thematic artifact creature that provided mana ramp for players. It reflects the set's aesthetic of epic fantasy filtered through the lens of classical antiquity.

The card features artwork by Chase Stone, who was tasked with visualizing a creature that felt both mystical and foundational to the world of Theros. The design process focused on ethereal, glowing elements to signify its status as an construct imbued with magical energy. Upon release, it was well-received by limited-format players for its reliable utility and consistency in various deck builds.
