Duel Recap

 * Turn 1: Duel Machine draws 5 cards, then sets a monster face-down in Defense Position and ends its turn.
 * Turn 2: Seto Kaiba draws 5 cards, then sets a card before summoning "Battle Ox" in Attack Position. He has "Battle Ox" attack the face-down monster, "Cyber Jar". Its effect activates, destroying all monsters on the field. Both players then pick up five cards from their Decks, and Special Summon any Level 4 or lower monsters to the field. The Duel Machine sets two monsters face-down in Defense Position; Seto Kaiba Special Summons four monsters ("Maha Vailo", "Dark Zebra", "Boar Soldier", and "Hitotsu-Me Giant") in face-up Attack Position. Seto Kaiba then ends his turn.
 * Turn 3: Duel Machine draws one card, then Tributes both of its face-down monsters ("Aqua Madoor" and "Wall of Illusion") to Tribute Summon "Blue-Eyes White Dragon". Since Seto Kaiba has a face-down card, it chooses not to attack, and ends its turn.
 * Turn 4: Seto Kaiba draws one card, then Tributes his "Hitotsu-Me Giant" to Tribute Summon "Dragon Seeker", placing it in face-up Defense Position (intending to use its effect on the following turn).
 * Turn 5: Duel Machine draws one card, then sets a card face-down before summoning "Lord of D." in Attack Position. (It's effect negates any other effects that target Dragon-Type monsters.)
 * Turn 6: Seto Kaiba draws one card. After switching "Maha Vailo", "Dark Zebra", and "Boar Soldier" to Defense Position, he ends his turn.
 * Turn 7: Duel Machine draws one card, then activates "The Flute of Summoning Dragon", using its effect to Special Summon two "Blue-Eyes White Dragon". It then activates its face-down card, "Polymerization", to Fusion Summon "Blue-Eyes Ultimate Dragon". Since "Blue-Eyes Ultimate Dragon" was Fusion Summoned this turn, it can't attack, so the Duel Machine ends its turn.
 * Turn 8: Seto Kaiba draws one card, then Tributes "Boar Soldier", "Dragon Seeker", and a face-down monster ("Dimensional Warrior") to summon "Obelisk the Tormentor". By Tributing his remaining two monsters ("Dark Zebra" and "Maha Vailo"), Seto Kaiba activates Obelisk's "God Hand Crusher" effect, and attacks the Duel Machine's "Blue-Eyes Ultimate Dragon" with Infinite ATK and DEF, destroying "Blue-Eyes Ultimate Dragon" and reducing its Life Points to zero. Seto Kaiba wins.
