Why did i get multiple duplicates and not even 1 good card its all common and some uncommon?

Because you brought from the wrong seller.

What the different betqeen limited vs original version ?

I got better cards in the limited .

How can you tell the fake cards from the real ones?

you can typically tell just by the look and feel of the card, but the only way I know to tell for sure is by performing a "rip test". You can find details about rip test online.
