I use the Tarot of the Spirit deck that I bought in 1993. It's pretty worn, but still quite lovely. A friend gave me a brand new deck a couple of years ago to replace it - same deck, just shiny new. I still haven't broken open the new deck. Something about "my" cards that is just comfortable.
I pulled it out to read for a student last week, and as she shuffled the cards, she said, "Oooh, this feels like a big comfortable bed." I never thought about it, but the cards seem to have a personality that soothes and comforts.
