However, there are a few things to be aware of:
* Rarity: While Exodia is a real card, there are different rarities. Some versions, like the original "Legend of Blue-Eyes White Dragon" cards, can be very rare and valuable. Be cautious when buying extremely rare versions, as they can be counterfeited.
* Printings: Over the years, Exodia has been printed in numerous sets and with different art. While all are real cards, some versions may be more desirable than others.
* Fake Cards: Sadly, fake Yu-Gi-Oh! cards do exist. When buying from unknown sellers or online marketplaces, be cautious and check for signs of authenticity.
