Clow Cards - The cards created by Clow Reed. These cards have magical spirits and cause mayhem if let loose. Most cards are only pranksters and don't hurt anyone/thing.
Sakura Cards - Sakura Cards are Clow Cards that Sakura turned into her own. They have more power then Clow Cards because Sakura used her own magic to make them and now owns them.
Lasin Board - This is a board used by Li. It has a bunch of elemental oracles on it and they help him to find any loose Clow Cards. That makes you think, why doesn't he just ask where the Clow Cards are before they cause all that trouble?
Sealing Wand - Sakura's sealing wand is used to seal a card. She must say an incantation and strike most of the times air, and the cards spirit gets sucked into the card. The Sealing Wand can also use the cards magic, just like Sakura does a lot with the Fly Card. The Sealing Wand uses it to grow wings and Sakura flies around on it like a broomstick in search of other Clow Cards.
Key of Clow - The Key of Clow is just the Sealing Wand, only smaller. It's also used to open the Clow Book. When Sakura wants to use the Sealing Wand, she must say an incantation.
