Duel Masters (デュエルマスターズ, Dyueru Masutāzu) is a franchise based on a manga, anime and a trading card game. The English-language version of the series made a three-episode preview premiere on Cartoon Network's Toonami block on February 27, 2004 (although it was somewhat edited for time.) The episodes then made their "official" premiere on April 13, 2004 on CN's Toonami spinoff block, the Saturday Video Entertainment System (also known as SVES or Saturday - the block is now canceled) with fewer edits as well as episodes 4 & 5. Toonami then moved to Saturdays and premiered the rest of the series from then on. "Season 2" premiered on March 26, 2005. Season 3 began production in September 2005.
