Angel Cards do not conform to any one particular system therefore the number of cards in a deck can vary. Most have pictures, and some, like the Angels of Light cards do not. Angel cards give angelic wisdom and help give more clarity and input into our lives.
The Doreen Virtue Angel Cards have proved to be probably the most popular Angel Cards over the last 5 years or more, and these normally have a instruction booklet with them, but there are many other really good decks. The "Original Angel Cards" are the most simple with little one word cards. The Diana Cooper Angels of Light cards are great if you want the text on the card rather than in a book.
There is wisdom in each card, and we can normally recognise this. The “magic” is really how can we shuffle and pick the “right” card for us at the right time. My view is that all is connected in ways that are often beyond our comprehension, hence giving us the answers we need right now. But others will have their own answers. (Brett)
