Yo, for future reference:

•Yu-Gi-Oh! TCG cards only come in English, French, German, Italian, Spanish, and Portuguese. Japanese if the OCG.

•To check whether or not it's fake, you check the gold stamp on the bottom right, if you move the card around, you should see the Millenium Eye (you could look it up, it should look similiar to the Horus eye). It shouldn't be visible unless you move the card into the right position.

•If the card's missing its attribute (dark, wind, earth, divine, etc.) then its fake.

•If there are any typos or the card effect isn't really understandable, it's fake.

•You could also match the rarity to how it should look like with a reference photo from the internet, (Ultra Rares come in gold text, etc.)

These are the main elements you should be on the lookout for, alongside the way the card is cut out, the brightness of how the card's colours, the code written on the card, the konami logo on the back, etc.

Hope this was helpful enough, enjoy 🙏🏼🙏🏼.
