This listing is for a very rare Erik's Curiosa curio from Sorcery TCG's beta set. Erik's Curiosa was part of the alpha version of the game, but was removed for the Beta set except as a special curio version. Although this curio card looks similar to the alpha version, the curio was printed using a better set of printers that were used for the beta set versus the alpha set.
The video below has examples of what these cards look like under a microscope.
