I recently bought cards from cardmarket and I suspect that some of them might be fake. The two fact that make me suspect are the unusual corners and the less rigid, more paper-like touching they have (although it is not paper at all).
I contacted the seller and he assured me that they are not fake, that all of his cards have been opened from Magic official products. He has more of 55K sells in his profile and all of his reviews are 100% Very Good. Moreover, all the cards that I bought cost between 0.02€ and 0.10€.
The seller also says that Magic has many manufacturers, so it is normal that all cards are different from each other.
Is this true? What should I do or believe?
I attach 3 image with link to drive (they are too big to attach them directly) from Spit Flame and Graf Rats, two from a bunch of the set I received which I suspect they might not be real. Behind them is a card from my collection that I know it is real for comparing them.
