Checking the expansion symbol is sometimes a hint to identify fakes, the symbol on most modern era cards is crisp and printed just in black white. If you see a print pattern in the black or the symbol is blurry it is most likely a fake.

If you check out the pictures below pay attention to the arabian nights symbol, as you can see the original one has a black dot pattern which is perfectly fine, but now other colored dots are inside. The fake one can be clearly identified by the colored dots inside. There are some fakes currently making the round with better printing than the one below but these can be identified by the completely missing black dots inside the logo.
