Provenance

Where it came from

Stamp of Approval was released in 2017 as part of the Unstable set for Magic: The Gathering, a silver-bordered expansion designed specifically for casual, novelty play. The card was created to lean into the set’s central mechanical theme of 'contraptions' and 'augmentation,' utilizing the unique rules space of Un-sets to challenge standard gameplay interactions.

The artwork was commissioned from Zoltan Boros, a veteran illustrator known for his dynamic and intricate contributions to the game's aesthetic history. In this piece, Boros rendered a whimsical, bureaucratic tool that reflects the card's function of imposing restrictions on opponents, capturing the lighthearted and slightly mischievous design philosophy that Wizards of the Coast intended for this particular block of cards.
