The series premiere of "Zatch Bell" – the latest anime sensation on Cartoon Network – was watched by more than one million viewers. The second episode that aired two weeks later drew an audience of 2.5 million. In addition to the series’ overwhelming surge in popularity, the game has a unique feature: it uses a spell book to hold players´ cards and count their life points. Players lose when they flip to the last page in the spell book. It sells for $9.99 a starter deck, $3.99 a booster pack and $3.99 a spell book.
