The Ojamajo Doremi Card Game Collection, known in English-language markets as Magical Doremi, was a series of collectible card sets produced by Amada Printing MFG in Japan beginning in 2002 and running through early 2006. The game is tied to the beloved Toei Animation magical-girl series Ojamajo Doremi, which aired from 1999 to 2003 across four seasons and associated media. Six sets were released in total, covering each anime season, the OVA Na-i-sho, and the video game Ojamajo Adventure: Naisho no Mahou. In play, each participant takes the role of one of the series' characters and works to resolve challenge cards called Happenings, earning reward points for each success. The first player to accumulate 100 points wins. Official tournaments were held during the game's active print run. The game ceased production after the sixth set and has been out of print since approximately 2006.
