[[SetoKaiba|Seto Kaiba]] has just managed to summon "[[Obelisk the Tormentor (anime)|Obelisk the Tormentor]]". The second mouth effect of "[[Slifer the Sky Dragon (anime)|Slifer the Sky Dragon]]" then activates, which reduces the ATK of "Obelisk the Tormentor" by 2000 ("Obelisk the Tormentor": 4000 → 2000/4000). Kaiba sets two cards ("Command Silencer" and "[[Life Shaver (anime)|Life Shaver]]"). On Kaiba's End Phase, the second mouth effect of "Slifer" expires for "Obelisk" ("Obelisk the Tormentor": 2000 → 4000/4000).

Yami Yugi draws ("Slifer the Sky Dragon": 2000 → 3000/2000 → 3000). He then activates his face-down "[[Pot of Greed (anime)|Pot of Greed]]" to draw two cards ("Slifer the Sky Dragon": 3000 → 5000/3000 → 5000). "Slifer the Sky Dragon" attacks "Obelisk the Tormentor", but Seto Kaiba activates his face-down "[[Command Silencer]]" to negate the attack and draw a card. Yami Yugi then sets two cards ("Slifer the Sky Dragon": 5000 → 3000/5000 → 3000).

Seto Kaiba activates "[[Thirst for Compensation]]" from his hand to [[Special Summon]] "[[Blade Knight (anime)|Blade Knight]]" (1600/1000) and "[[Sword of Soul]]" (0/1900) from his hand in face-up Defense Position. The second mouth effect of "Slifer the Sky Dragon" activates, which would destroy both summoned monsters, but Seto Kaiba activates "[[Card Guard (DM)|Card Guard]]" from his hand to prevent "Sword of Soul" and "Blade Knight" from being destroyed this turn by discarding one card ("[[Kaiser Sea Horse (anime)|Kaiser Sea Horse]]").

Yami Yugi draws ("Slifer the Sky Dragon": 5000 → 6000/5000 → 6000). "Slifer the Sky Dragon" attacks "Obelisk the Tormentor", but Seto Kaiba activates his face-down "[[Power Balance]]" to force Yugi to discard half the cards in his hand and allow Seto Kaiba to draw the same number of cards Yugi discarded. Yugi is currently holding six, so he discards "Collected Power", "Electromagnetic Turtle", and "Chain Destruction" ("Slifer the Sky Dragon": 6000 → 3000/6000 → 3000). Yugi's hand now contains "[[Magical Hats (anime)|Magical Hats]]", "Spell Textbook", and "Necromancy".

Yugi then activates "[[Necromancy]]" ("Slifer the Sky Dragon": 3000 → 2000/3000 → 2000) to [[Special Summon]] "Blade Knight" (1600/1000), "Sword of Soul" (0/1900), "Kaiser Sea Horse" (1700/1650) and "[[X-Head Cannon (anime)|X-Head Cannon]]" (1800/1500) from SetoKaiba's Graveyard to his side of the field in Defense Position. The second mouth effect of "Slifer the Sky Dragon" activates ("Blade Knight": 1600/1000 → 0; "Sword of Soul": 0/1900 → 0; "Kaiser Sea Horse": 1700/1650 → 0; "X-Head Cannon": 1800/1500 → 0). Due to the third effect of "Slifer" (''If a monsters ATK is 2000 or less that monster is destroyed''), the newly summoned monsters are all destroyed.

Due to the second effect of "Necromancy", SetoKaiba's monsters lose 600 [[ATK]] for each "Necromancy"-summoned monster that was destroyed until the End Phase ("Obelisk the Tormentor": 4000 → 1600/4000). Since "Sword of Soul" was destroyed and sent to the Graveyard, its effect activates, allowing Seto Kaiba to increase Obelisk's [[ATK]] by 1000 ("Obelisk the Tormentor": 1600 → 2600/4000). Yugi activates the effect of "[[Electromagnetic Turtle (anime)|Electromagnetic Turtle]]" from his [[Graveyard]] to immediately end the [[Battle Phase]].

Kaiba draws. "Obelisk the Tormentor" attacks "Slifer the Sky Dragon", but Yugi activates his face-down "[[Spell Textbook]]" to discard all cards in his hand ("Magical Hats") ("Slifer the Sky Dragon": 1000 → 0/1000 → 0) and draw a card. If that card is a [[Spell Card|Magic Card]] Yugi can activate it. Yugi draws "[[Card of Sanctity (anime)|Card of Sanctity]]" and subsequently activates it, allowing both players to draw until they're holding six cards, letting Yami Yugi draw six cards while Kaiba draws two cards ("Slifer the Sky Dragon": 0 → 6000/0 → 6000). Seto Kaiba activates his face-down "Life Shaver" to force Yugi to discard one card from his hand for each turn that "Life Shaver" was on the field. "Life Shaver" was set on the field for two turns ("Slifer the Sky Dragon": 6000 → 4000/6000 → 4000).

* [[Life Shaver (anime)|Life Shaver]]<ref group=Notes name=exchange>This card belongs to Yugi, but it was taken by Kabia via "[[Exchange]]" two episodes ago.</ref>
