In the past I have also given decks away if I have not felt a connection develop, or if I did not like the energy of the cards. I had a beautiful Thoth deck about 15 years ago that I gave away, because as that time I found the artwork too disorienting. These days however I wish I had saved that deck. So what I am saying is maybe it isnt the right time to work with the deck. Also, it might take a time for the cards to absorb your energy. I handle mine a lot before I start reading with them if I get a new deck. Really I have 2 decks that I would say are my 'working decks'. I kind of collect others wherein I like the artwork/symbolism. There has to be classic occult symbolism or they just don't tend to work as well for me. I have a couple of oracle decks but I tend to use these as complementary to a tarot reading whereby the querant is drawn to that deck or it seems right to use for that particular situation.
