How can I tell if my Karumonix, the Rat King is real?
Karumonix, the Rat King is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the print quality and cardstock (real cards have a distinctive blue inner core visible from the edge), the rosette pattern on the back, the security stamp on planeswalker / mythic cards from recent sets, and confirm the collector number and set code match the official Scryfall record. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
