There are many card decks to choose from, but I prefer to use the traditional Rider Waite deck, and the 22 cards are numbered 0 through to 21.Most decks are based around the cards, even angel and oracle cards. Once you learn to read the cards as a spread, whatever the deck, you will see emerging patterns; the same cards may shout out, or cards with the same numbers.
While the major arcana have a stronger message, minor ones can help reinforce that message; for example the Kings are versions of the Emperor. A reading with Kings and the Emperor would have a strong message of stability and responsibility. The cards are tools, to stimulate what our intuition is already telling us.
