Actually, I'm almost not surprised cause my tarot cards are working fantastically freakishly well lately too. I'm something of a collector.
I got my first tarot deck two summers ago, the Goddess Tarot (Which is BEAUTIFUL). They worked well with me and I loved them so. A few months ago I buckled and got the Rider-Waite deck, which I had always sworn I would never get, not because its such a popular deck, and nearly every collector I've known has the deck, but because the pictures were not eye-candy like the Goddess deck. But nonetheless, I got the mini-deck and its so adorable...it was ten bucks, I didn't care. I'm going to be giving those to my cousin.
Then I got two more decks at Barnes & Nobles, I'd say in the last week or so. They were on sale for 75% off and anytime you can get something you love for that much off (And especially if they run 16 bucks a deck as the ones I got were) you POUNCE on that chance.
I got the Lord of the Rings Tarot and on the advice of the friend with me, Alister Crowley's Thoth Tarot.
I got to know the decks and got to know the feel of how they would work for me, and how I would work for them, just as I had done with my other two decks. (Or tried to, in the Rider deck's case)
I tried the LOTR first, since I was more familiar with the series. They worked fine and we had a great relationship.
But nothing prepared me for what happened with the Thoth deck.
I shuffled the deck the first time and laid the cards out as I always do (Celtic Cross fashion, ugh, will SOMEONE hook me up with a few good book titles of tarot spreads or a website which illustrates thusly because I'm not exadurating when I say thats one of the entire THREE spreads I know) and I was floored by their accuracy. Those cards have NEVER been wrong on me, and I'm not yet comfortable to read for others with the deck yet ( I carry my Goddess deck with me always and if I'm asked by a friend to read, I use those) but I will probably only use those for my own use and adopt another deck strickly for reading for friends.
