There are a countless amount of counterfeit Yugioh cards in the market. I'm not sure how they get around, but your kid must have gotten it from some friends at school.
Wow I wasn't even aware. Well maybe someone would want it my kiddos don't really play them anymore so there are tons of cards laying around. I just listed the ones I thought were good.
You can tell a fake by the quality of the card (such as poor grammar or poor quality images). The actual card Fushioh Richie should have gold lettered text and be shiny.
