Here is the explanation about different types of decks.
The Rider-Waite tarot deck may well be regarded the most popular Tarot deck in use today. The images were drawn by artist Pamela Smith to the instructions of occult writer A.E.Waite and further published by the Rider & Company. Though the images are simple, the card backgrounds hold a rich blend of symbolism.
One can easily distinguish the Rider Waite deck from other Tarot Decks owing to the fact that the pictorial representation of each card is in itself very significant of its origin.
The Oracle Deck is also a set of cards but may or may not be as significant as Tarot cards in terms of symbols of the major and minor arcana.They are used primarily for fortune telling or even for meditation. Meditating on these cards helps bring clarity of thought.
The artwork decorating the deck of Gipsy Tarot tsigane is nearly whimsical. Because of the bright colors used in these cards this deck has gained very much popularity among many readers, amateur and pro alike.
The 4 suits from this deck are described as society's four castes and many of the interpretation is credited to gipsy.
