# Crystal Skull, Isu Spyglass This rare artifact from the Assassin's Creed crossover set appeals to collectors interested in Magic's licensed properties and artifact-focused decks. The card's thematic design—connecting to the Isu mythology central to the video game franchise—makes it notable for fans of both properties seeking crossover memorabilia. Collectors typically pursue this card for constructed play in artifact-heavy strategies rather than as a premium collectible. The standard nonfoil and foil variants offer modest differentiation. Its appeal remains primarily functional rather than driven by scarcity or special treatment, making it a straightforward acquisition for those building themed collections around Assassin's Creed or artifact synergies.
