Some tarot decks can give you a very different vibe to, if they're unique enough from the basic symbolism. It can significantly alter the message. And yes, the esthetics

I have one classic tarot deck, one pocket edition with very different images and I just ordered one with more slavic twist to it's visual interpretation. I'm Polish, so that's kind of a must have for my brain XD
So that will be my third and probably last tarot deck. I too think it's unnecessary to have many, many tarot decks. Oracle decks are a different story. Good thing I'm all for esthetics and I don't find every other deck beautiful. I'd go bankrupt. They're all so expensive

But it's understandable.
