How can you tell the difference between real and fake yugioh egyptian god cards?

You see. I have some egyptian god cards and I can't find anything wierd about them but just in case, I want to know if they are real. Can anyone tell me if they are fake or not? Oh, and if this helps, they have colored backs.

They do not have the Yugioh or Konami logo on the back, but the backs are colored (red for Slifer, blue for Obelisk, yellow for Ra). In the lower left corner of the card, it has Japanese text. There is a version of each god card that has English text saying 'this card cannot be used in a duel', but the GB versions have it in Japanese, while the rest of the card is English. The GB version has Gold text.
Reply:if they cheap they usually fake get them at card stores they dont sell fake cards
Reply:if you could post a link of a picture of them then I could help you. Either that or give a little bit more detail.
Reply:Just so you know. They don't really have any effects, but I think they are real. The egyptian god cards are different from other cards in appearance, so I don't know if they are fake or not.





I don't think you should buy them if you were thinking of doing that because you can't use them in a duel. The card that I really want is Mirror Force. Man I need that card.
