The traditional tarot deck has 78 cards. 22 major and 56 minor. The minor comprise of 4 suits (numbered 1 to 10 each) and 16 court cards (4 for each suit).
Oracles vary greatly in how many cards are included. Some don't even use cards, they may use stones, or sticks, or bones, or coins, or dice, etc.......
Hope this helps!
