"The Master of Magicians, Part 3", known as "The Magician's Disciple - Dark Magician Girl" in the Japanese version, is the sixty-second episode of the Yu-Gi-Oh! anime. It first aired in Japan on July 3, 2001, and in the United States on February 8, 2003.
Arkana tries to use a hidden key to break himself out. However, Marik plays tricks on his mind using his Millennium Rod (making it look as though Arkana didn’t have the key in his hand). Yami Yugi turns back into Yugi, who breaks himself and Arkana out of their locks.
Marik speaks to Yugi through Arkana and tells him of his motives and plans. Just afterwards, Téa, Solomon Muto, Mokuba and Tristan find Yugi.
A replay occurs, and Arkana, knowing that Yami Yugi has only one "Dark Magician" in his Graveyard (which would make the ATK of "Dark Magician Girl" 2300), uses his "Dark Magician" to attack "Dark Magician Girl". However, Yami Yugi then reminds Arkana that "Dark Magician Girl" gains ATK from "Dark Magicians" in both players' Graveyards ("Dark Magician Girl": 2000 → 2600/1700). "Dark Magician Girl" then destroys Arkana's "Dark Magician" (Arkana 750 → 650) ("Dark Magician Girl": 2600 → 2900/1700).
During this episode, Yami Yugi criticizes Arkana for indiscriminately Tributing monsters to inflict damage to his opponent's Life Points. However, in a later episode, Yami Yugi ironically uses the same strategy himself against Rafael, and also loses when the presence of monsters in his Graveyard allows an opposing monster to increase its own ATK. Of course these situations were different: Arkana did this of his own accord, whereas Yami was under the influence of "The Seal of Orichalcos", which corrupts their users.
And in another irony, in another later episode, the same duelist who defeated Yugi from before also used this strategy while under the influence of the same field spell that corrupted Yami in order to power up his most dangerous monster, but the Pharaoh managed to defeat it by reviving the very same monster that was used to defeat him before. Afterwards, Rafael purposely lost the duel in order to apologize to his monsters for his treatment of them — which was shown to have freed him from the Orichalcos.
From a close-up near the episode's beginning, the buzzsaw near Yami Yugi has its right side close to the number 1000, but the next view of the saw, from far-away, shows its left side closest to the number and the right side touching the vertical line that means 500 life points. Then the next close-up shows it as the first view again.
When Arkana places "Shadow Balance" on the field, he calls it a Monster, when in fact "Shadow Balance" is a Trap.
When "Gazelle the King of Mythical Beasts" is summoned, it's shown with three claws on its front paws. However, just before "Shadow Balance" "swallows" "Gazelle", it has four claws on its front paws, then back to three just moments before it's destroyed.
