I absolutely get the collecting mindset. Among other things, I collect unusual non-Tarot of decks just to have them. Sometimes they'll get some use, sometimes they'll just sit there as a novelty. And that's fine. But I feel differently about Tarot (and a few others that I work with regularly). They have to be "just so". I've bought quite a few decks over the years simply because I loved the few cards I'd seen online or was attracted to the overall theme, but once I had them I quickly realised that there were cards that just didn't work for me or the atmosphere of the deck as a whole wasn't right for me. And so I've sold quite a few decks over the years. Kept a fair few as well, mind you, but even so, as far as Tarot is concerned, I read almost exclusively with my beloved Rider Waite Smith.
