A number of non-foil, double-sided Ixalan cards in English, Portuguese, Spanish, Chinese (Traditional), Chinese (Simplified), and Korean were mistakenly printed on the incorrect card stock. Although not printed on typical Magic card stock, these cards contain the unique holofoil stamp applied to all rares and mythic rares that guarantees authenticity. They are real Magic cards made by Wizards of the Coast and are tournament legal.

A full list of the affected cards is below. If you have questions, please contact Customer Support at (800) 324-6496 or @Wizards_Help on Twitter and we'll be happy to help.
