"The Master of Magicians, Part 1", known as "The Black Magician User - Pandora" in the Japanese version, is the sixtieth episode of the Yu-Gi-Oh! second series anime. It first aired in Japan on June 19, 2001, and in the US on February 8, 2003.
Yami Yugi and Arkana are dueling in an underground chamber, which blocks the transmission to the KaibaCorp building.
Whoever loses will have their legs cut off (or be sent to the Shadow Realm in the English version).
Whoever loses must relinquish their "Dark Magician" to the winner.
In the Japanese version, if the saw reaches the number zero, it will slice the players legs off. In the English dub, they are called dark energy disks and when they reach the number zero, the player's mind will get sent to the Shadow Realm.
The saws are made glowing in the dub to make them look like Dark Energy Discs.
A scene of Zeus sealing the box and Pandora opening it, and tiny little hope left in the bottom of the box, is cut from the US version.
Numerous changes were made to shots of the hands of both Duelists, including the addition of Egyptian Gods it would be impossible for them to have. Pictures and details can be found here.
The harlequin that points out where Yugi has to go is silent in the original. In the English version it speaks to Yugi as it points out what Yugi needs to do.
