I don't know that one. I'm leery of anything to do with the Necronomicon though.

But, to contribute something, my favorite decks are:

Osho Zen Tarot

LS Gothic Vampire Tarot 

Osho Zen has beautiful artwork, and is a good meditation deck. It was my first, and it's definitely one I recommend to anyone and everyone.  I haven't met very many people who didn't like the deck.

LS Gothic Vampire deck has slightly horrible artwork (anyone that likes it... I'm sorry.  I just don't really find it aesthetically pleasing), but it has a really good vibe for me, and has quickly outstripped my Osho Zen deck in recent usage. It's a more traditional deck, with the same general principles as the Rider-Waite, with a few variations unique to the deck and the authors interpretation.

I don't own the Necronomicon deck, but I've heard from others who do that it is mostly an art / collectible kind of deck.  I do love Anne Stokes' artwork, though. 

I am currently looking forward to the Wizards Tarot, The Gaian Tarot (finally!) and the re-release of the WildWood Tarot.  All can be found on the pre orders page at Tarot Garden.

I got a new deck in the mail today. The Steampunk Tarot published by Llewellyn. I started feeling a little "tug" toward the tarot a while ago and this deck caught my eye. Life being what it is I haven't had a chance to examine it thoroughly but what I've seen I like. 

Sent Llewellyn an email about the card. Now I wait.

The missing card arrived today and I spent some time with the book that comes with the deck. IZ HAPPY! This author doesn't use "reversals" and I'm going to try her system and see how it goes. In any event, I love the art and the images are quite intriguing...
The set doesn't have a separate box to keep the cards in, just the box for the set, so I'll be getting out my black cardstock, scissors. glue and bone folder soon to make a slipcase for the deck.
