Yugioh season 1 episode 13
Joey says its okay as they are all friends so it doesn't matter. Yugi reveals that the one dueling is the "other Yugi" who is a spirit dwelling inside the Millennium Puzzle, and apologizes for not telling the others. Joey and Tristan express their confusion as to why there are two Yugis. In the same turn he uses " Reborn the Monster" to revive Tristan. Unsure of what to expect, he Summons it and regular Yugi emerges, but Yami Yugi is still playing. In his new hand, Yami Yugi holds the " Dark Magician", his own favorite card. Yugi is glad that he didn't have any of his friends cards in his hand at the time. Joey defeats the "White Magical Hat" but in his pride he recklessly takes out a face-down monster, " Morphing Jar", which forces both players to discard their hands and draw 5 new cards. Yami Yugi explains the situation to Joey so he offers to help in any way he can. Like Tristan, Joey emerges from the card, six inches tall and dressed as the "Flame Swordsman". Since "Flame Swordsman" is Joey's favorite card, Yugi correctly deduces that it will contain Joey's soul. Yami Yugi Summons the " Flame Swordsman" to defeat Yami Bakura's "White Magical Hat". Tristan wanders around the graveyard and finds a tombstone with his name inscribed on it. Yami Bakura summons " White Magical Hat" and destroys "Cyber Commander", sending Tristan's soul to the Graveyard, and says that the God of Death will get there soon and if it does, Tristan's body will die. Tristan emerges from the card, six inches tall and dressed as the Cyber Commander.
The Duel starts and Yami Yugi summons " Cyber Commander", noting that it is Tristan's favorite card. The pair start a Duel with Yugi's Millenium Puzzle and his friends' souls at stake. Yami Bakura reveals he is not the real Bakura and after Yugi asks him his objective, he mentions that Yugi should know that whoever has all 7 Millennium Items will have everything. Yami Yugi asks Bakura if he's a duelist of the Dark Games.
