The Clow Cards were magical cards created through a mix of Eastern and Western magic revolving around concepts of natural forces and elements from the powerful sorcerer, Clow Reed. To contain their power, Clow sealed the cards within a magical book until they were released by Sakura Kinomoto who came across the book within the basement of her household. With all the cards released, Sakura became tasked with sealing the beings representing each Clow Card and was eventually successful in gaining possession of all of them. Through her magical power, Sakura eventually converted all the cards into Sakura Cards which gave her full control over their power as she surpassed Clow Reed.
The Clow Cards take on varying forms and possess differing personalities ranging from good-natured to violent. To gain ownership of a captured card, the owner must sign their name on the back of it or else they will eventually go free again with time. Yue and Keroberos are their guardians, with the cards each being aligned to the guardians based on their affiliations with the moon or sun. The Hope and Nothing cards are not associated with the two guardians since Nothing was created as a counterbalance to the other Clow Cards and the Hope was made as a result of Sakura's power.
There are some differences with the plot and elements to the Clow Cards between the anime and manga. In the manga, there are only 19 cards and Sakura had ownership of all of them. In the anime, there were 53 cards and ownership of them was divided up between Sakura and Syaoran until the former gained complete control over them after defeating Yue in a battle to prove her worth as master of the Clow Cards.
The Clow Cards in the manga include The Windy, The Wood, The Jump, The Fly, The Watery, The Illusion, The Flower, The Sword, The Thunder, The Shadow, The Mirror, The Shield, The Maze, The Erase, The Glow, The Dark, The Light, The Firey and The Earthy.
When Syaoran was able to gain control over whatever Clow Cards he defeated in the anime, he became capable of utilizing the powers of The Dash, The Dream, The Freeze, The Return, The Sand, The Storm, The Time and The Twin.
