There's no UK market activity on this card in the last month—no listings or graded sales to speak of—so the £56.22 price sits entirely on Cardmarket data with nothing local to anchor it. That makes it harder to judge whether this is fair value or stuck in an echo chamber, so tread carefully if you're thinking of buying or pricing one yourself.

• NotableNo UK listings or graded sales in the last 30 days. Cardmarket is the only reference.
