Well i have 3. The ghost tarot. And the ghost and spirits tarot with the angel tarot. The angel tarot i didnt use very much its a up back. too do some people being scary in the cards if the other tarot i use. the other 2 called out to me is why i have them.
I've been using the Druidcraft deck for about nine years. I had yet to find another deck whose artwork influenced me to purchase it until recently when I stumbled across the Dark Grimoire deck. Though, I don't seem to be connecting to the Dark Grimoire deck very quickly. A great website you can browse through decks on is Aclectic Tarot (google it). You can also find tarot decks for decent prices on Amazon.
I have the tarot nova, Rider-Waite, Celtic oracle decks and one large tarot deck I'm unsure of the name but I have no connection to the deck so have never used it.
Now I have set myself the task of designing my own deck and I don't look back on starting it. It's now becoming a really personal deck to me and I have been able to make every element of it my own.
I recommend doing this to anyone who has the time and patience.
I personally though rather new to the tarot. Own two decks. My first one was that Tarot to go. the artwork was nice and it wasn't too much on eBay so I purchased it as a starter. I've recently added The Wild Unknown deck to what I hope will be a great collection of decks that are visually stunning as well as a joy to work with. In the future I hope to add The Wild Unknown's Animal spirit deck as well as the Golden Thread and Luminous spirit decks from https://labyrinthos.co/products/luminous-spirit-tarot-deck-holographic-tarot-cards
I have a collection of both Tarot and Oracles, I'm not sure but at least over 75 decks, I have a cabinet full, and don't think I could squeeze another in.
Ciro has a web site you can check out his decks, (just type in his name, he is also on FB) I have all his but the Kipper his newest.
Another deck Shadowscapes by: Stephanie Pui-Mun Law is a beautiful deck, you should look that one up and check out the images. I love it.
I just have to many to list, but I love the Lenormand, its easy to learn, and the Shadowscapes is just beautiful!!
