I dont believe there is such a thing as "fake/unreal" tarot cards.
Its kind of a you get what you put into it deal.
If you work with your cards and familiarize yourself with its imagery and actively put energy into your deck it will treat you well and give you clear readings.
If you are you are worried you will not end up with the rider-waite interpretation in imagery, then buy the rider-waite deck… its the easiest to find.
Or if you needed a tarot deck with full major and minor arcana, just avoid buying an oracle deck. (Not held to the arcana structure, more loose for interpretations)
Its quite easy once you start looking into buying your first deck. And dont let any elitist tell you "you have to be gifted or inherit your first tarot deck"
