Hello! I actually collected the sets a little while back now with the intention of using them for divination and that's the one thing I haven't used them a lot for YET! What I do is go through them for inspirational pictures, prettying up a space or representing the seasons. I'm pretty sure there's another board with suggestions about how to store them and use them which helped me come to my purchasing decision.
A couple things I'd mention about them are:
~They are as beautiful as imagined, the quality is lovely too.
~They're large, really large cards. I don't have access to mine at the moment but I'm quite sure they're even bigger than the Blue Angel oracle card size. I have bigger hands and don't find shuffling anything of an issue but it's something to think about.
~Also, if you do get all the sets, that's a lot of cards! They're hard to store and shuffle that way. Because of that, they didn't really give me a "deck" vibe. That said, you may like to only collect collections and personalise your deck more than I have.
~The backs have writing and prompts on them which I actually find helpful for stimulating intuition. They haven't been a problem for me and I haven't been distracted by the writing on their backs.
In all, they're just gorgeous. I understand the unintended feeling that you need to collect all the sets to get out of them what you're hoping. I'd suggest to really pick the sets you can see yourself conversing with. Some sets have a couple artworks that I love but the rest of the set is a tiny bit more dull and I don't seem to interact those. Also, the Halloween set is full on for drawing out the shadow. It can be quite abrasive because it's quite graphic. There is definitely a great mix of light, dark, fairytale, symbolism and nostalgic story time elements here anyway (without that deck). It's one that I think benefits from you working with it in the sense of nutting out all the symbolism, spending time with drawing out meanings from adulthood and childhood and defining archetypes etc. It's a juicy endeavour! Hope this helps!!
