I have read professionally and used the same set for 15 years. I started on a psychic 900 line while I was still new and inexperienced. I often thought I needed another deck to "see" the things I tended to miss. As if my deck had a short coming of some sort or only dealt with certain issues. As I gained experience I began to realize that my tarot cards weren't lacking in any form, it was my perceptions and understanding.

Funny enough, as much as I have liked and collected other decks, I don't feel I am able to read any except the Merlin, my original choice. I often thought this was a limitation on my behalf but now it is understood as a part of my nature and has provided me with an asset that allows me to focus, complete and in certain fields, develop a "specialty" or talent. (This does not mean a lack of talent or ability for people that read or use multiple mediums.)

What I have learned so far is that each deck is a language for personality types, for each type, the reader and the readie. Some people might need or excel with multiple decks. The deck chosen could be a reading all by it's self and can fulfil multiple purposes. I am certain that the deck will carry an influence, how significant would be circumstantial and relative mostly to the reading.

I often asked myself, "If I have mastered this Tarot set, why would I switch decks and if I haven't mastered this Tarot deck yet, why would change decks?" In this question the one thing I have learned about reading cards is that the cards carry specific messages and deliver the messages in the most efficient and effective fashion, (often efficient beyond my imagination). In other words, the message is usually quite different from what "I" think it will be or it is presented differently. In fact, I'll go as far as to say that the cards understand that people don't always hear what was said or the way it was said and adjust the message so it's "misunderstanding" (denial) is understood...sometimes like an "Idiot Savant".

The real importance in "reading" is not the method, experience level or ability, its the heart and motive of why you want to read.
