Lime green/gold mixed fine chunky glitter.
Inspired by the Seal of Orichalcos card from Yu-Gi-Oh
Fun Fact: When this card is played in a duel, both players are trapped inside until the duel is complete. The loser's soul is taken by the seal to help awaken the Great Leviathan; a powerful beast, controlled by Dartz, that would destroy the world to create a new one free of evil. (Season 4: Waking the Dragons)
