I can hardly remember anything about this cartoon, but it just came to my head for some reason. I know it had these cards which a girl collected and they were added to some kind of book. There were also enemies who I think tried to get the cards as well. They had different powers such as electricity and wind, and I think I remember one been like some kind of electric rabbit looking thing. I know I haven't provided much detail but if anyone has any suggestions I would really appreciate it, thanks.

It could be a show called Cardcaptors. Cardcaptors first aired in the United States on Kids' WB on June 17, 2000. Here is a YouTube link. See if its what you remember.
