Hi astroltina. I think that you can get accurate readings from any deck that you genuinely like/admire and enjoy. Some readers find that decks with specific themes (such as the Tarot for Cats, mentioned by MeeWah) lend themselves to certain types of readings more than others, because themed decks can facilitate the process of "tuning in" to particular issues or subjects. Basically, the psychology of the reader and how well he or she resonates with the imagery and symbolism of a deck is for me the most important factor in gaining accurate insights.
