Turn 2 : Dark Marik Dark Marik Summoned " Newdoria " in Defense Mode . Turn 3 : Dark Yugi Dark Yugi Set " Remove Trap " and Summoned " Big Shield Guardna " in Defense Mode . Turn 4 : Jonouchi Jonouchi did not get any Monster Cards in his opening hand , so he just Set " Shield and Sword " and ended . Turn 5 : Kaiba Kaiba said he would teach Jonouchi the food chain of the fight and got " Vorse Raider " to attack him directly . Dark Yugi hoped to preserve his and Jonouchi ' s Life Points and take out Kaiba and Dark Marik , so he got " Big Shield Guardna " to block the attack . Jonouchi was thankful of Dark Yugi ' s devotion to their promise , but still thought about how he needed to face Dark Marik . Kaiba mocked Jonouchi for needing Dark Yugi ' s help and commented on his low chances of winning in the semifinals . He suggested that Dark Yugi ' s determination to Duel Jonouchi was so he could have an easy opponent and guaranteed spot in the finals . Dark Yugi warned Kaiba to stop talking and argued that Jonouchi was a true Duelist who had won his way to this point in the tournament . Jonouchi requested that Dark Yugi stop and said he would see him in the next round . Dark Marik interrupted and suggested that they continue the battle . Turn 6 : Dark Marik Dark Marik decided that he wanted to face Dark Yugi and most get rid of the other two . He Set " Mirror Force " and Summoned " Lord Poison " . " Newdoria " attacked " Vorse Raider " , but having lower ATK , it was destroyed . This activated the effect of " Newdoria " , which Dark Marik used to destroy " Vorse Raider " . Since his monster was destroyed in battle , Dark Marik was to take 700 damage , but he activated " Spell of Pain " to make Jonouchi take the damage instead ( Jonouchi : 4000 → 3300 Life Points ) . Dark Marik planned on protecting " Lord Poison " with " Mirror Force " and sacrificing it next turn . Turn 7 : Dark Yugi Dark Yugi Sacrificed " Big Shield Guardna " to Summon " Archfiend of Gilfer " , which he used to attack Kaiba directly . Kaiba activated " Attack Guidance Armor " , equipping it to " Lord Poison " , making it become the target of the attack , but Dark Marik used " Mirror Force " to reflect the attack back to Dark Yugi , who used " Remove Trap " to cancel the effect of " Mirror Force " . " Lord Poison " became the final target of the attack and was destroyed ( Dark Marik : 4000 → 3300 Life Points ) . Turn 8 : Jonouchi Jonouchi drew " Gearfried the Iron Knight " and Summoned it . Since Dark Marik and Kaiba had their fields emptied in Dark Yugi ' s turn , Jonouchi had an open shot at either of them . With 14 hours left to save Mai , he decided he wished to face Marik , so he elected to attack Kaiba directly ( Kaiba : 4000 → 2200 Life Points ) . Turn 9 : Kaiba Kaiba Set " Ring of Destruction " and " Shrink " and Summoned " Blade Knight " , which he used to attack Dark Marik directly ( Dark Marik : 3300 → 1700 Life Points ) . Turn 10 : Dark Marik Dark Marik Summoned " Dark Jeroid " and contemplated on which monster to target with its ATK - reducing effect . Kaiba mentally urged Dark Marik to attack him , so that he could use " Ring of Destruction " to take away a large portion of his Life Points . Cautious of Kaiba ' s Trap Cards , Dark Marik targeted " Gearfried " ( " Gearfried " : 1800 → 1000 ATK ) . He then attacked " Gearfried " with " Dark Jeroid " , but Jonouchi activated " Shield and Sword " , switching each monsters ' ATK with their respective DEF ( " Gearfried " : 1000 → 1600 ATK , 1600 → 1000 DEF , " Dark Jeroid " : 1200 → 1500 ATK , 1500 → 1200 DEF ) . This would have allowed " Gearfried " to destroy " Dark Jeroid " , but Kaiba activated " Shrink " to halve its ATK ( " Gearfried " : 1600 → 800 ATK ) , causing " Dark Jeroid " to win the battle ( Jonouchi : 3300 → 2600 Life Points ) . Turn 11 : Dark Yugi Dark Yugi examined the situations of his opponents ; Kaiba had a monster and a face - down card , Dark Marik had a monster and no face - down cards and Jonouchi had no monsters or face - down cards . Having the monster with the highest ATK , he thought about who to attack . He Set a card and Summoned " Kuriboh " in Defense Mode . Dark Yugi was about to attack a monster , but was stopped by Jonouchi , who questioned him about what a real Duelist is . In conclusion , he said that Dark Yugi should not be protecting him for their promise to Duel each other . Being an opponent in the worst situation , he saw himself as the best viable target for Dark Yugi ' s attack , an opportunity Dark Yugi should take , as a real Duelist . He assured him it would not affect their friendship and vowed that they would meet in the finals , if they did not face each other in the semifinals . Dark Yugi understood and got " Archfiend of Gilfer " to attack Jonouchi ( Jonouchi : 2600 → 400 Life Points ) . As Jonouchi ' s pod moved past Dark Marik , he mentally warned Dark Marik to brace himself . Turn 12 : Jonouchi While Jonouchi drew , he promised Mai that he would save her . Jonouchi Set " Graverobber " and Summoned " Legendary Fisherman " . Dark Yugi thought that Dark Marik might be the wisest attack target , but Jonouchi chose to attack Kaiba ' s " Blade Knight " . Kaiba responded with " Ring of Destruction " , which would destroy " Legendary Fisherman " and take out Jonouchi ' s remaining Life Points . However Jonouchi activated " Graverobber " and took Dark Marik ' s " Spell of Pain " , allowing him to redirect the damage to Dark Marik ( Dark Marik : 1700 → 0 Life Points ) . With his Life Points at 0 , Dark Marik ' s pod ascended to the top of the tower , ruling him as a participant in the first semifinal . Dark Marik was not disappointed , but decided he would send Jonouchi to the darkness . Jonouchi had no cards left on his portion of the field , but that was what he had planned for and ended his turn . Turn 13 : Kaiba " Blade Knight " attacked Jonouchi directly ( Jonouchi : 400 → 0 Life Points ) , sending Jonouchi to the top of the tower , as the second participant in the first semifinal . With Dark Yugi and Kaiba undefeated , they were ruled as the participants in the second semifinal . Cards used . The following cards appeared in this Duel . Each player excluded one card from their Deck to determine the order of play .
