Dark Yugi and the Ventriloquist of the Dead's Duel

Dark Yugi and the Ventriloquist of the Dead's Duel was a Duel in the Yu-Gi-Oh! Duelist manga between Dark Yugi and the Ventriloquist of the Dead, during the Duelist Kingdom tournament. The ventriloquist used a puppet of Seto Kaiba to make his moves.

In the anime, it is replaced with a similar Duel between Dark Yugi and Ghost Kaiba.

Prior events
Saruwatari worked for KaibaCorp, but was secretly a spy for Industrial Illusions. After Seto Kaiba fell into a coma, Saruwatari managed to steal his Deck. He gave this to the Player Killer, the Ventriloquist of the Dead, who used it with a puppet to impersonate Kaiba.

Mokuba Kaiba attempted to steal Dark Yugi's Star Chips, hoping to disqualify him from Duelist Kingdom, which he believed would ruin Maximillion Pegasus' attempt to take over KaibaCorp. However he only managed to grab two of Dark Yugi's three Star Chips and Dark Yugi grabbed him by the arm before he could run away. Dark Yugi and Anzu Mazaki managed to convince Mokuba that they would help him stop Pegasus.

As Mokuba tried returning the Star Chips to Dark Yugi, he was stopped by Saruwatari, who told them that Star Chips could only be earned through Dueling. Dark Yugi challenged Saruwatari to a Duel for the Star Chips, but since Saruwatari didn't play, he arranged an opponent for Dark Yugi, the Ventriloquist of the Dead.

The ventriloquist spoke through the puppet, which pretended to be Kaiba and talked about wanting to kill Yugi as revenge. Each player bet three Star Chips. The ventriloquist held his hand of cards in his left hand and got the puppet to draw and play his cards. Dark Yugi was annoyed by how he was making a mockery of Kaiba, but the ventriloquist had hoped for this as he planned on intimidating his opponents.
