Yu - Gi - Oh ! Duelist - Duel 007 " The Trap " , known as " The Trap ! ! " in the Japanese version , is the seventh chapter of " Yu - Gi - Oh ! Duelist " and the sixty - sixth chapter of " Yu - Gi - Oh ! " . This chapter was originally printed in the " Weekly Shōnen Jump " magazine in Japanese . It has been reprinted in in volume 1 of " Yu - Gi - Oh ! Duelist " and volume 5 of the bunkoban . Summary . Dark Yugi and Haga continue their Duel . " Mammoth Graveyard " and " Killer Needle " have just been destroy ed each other in battle . Haga is annoyed that Dark Yugi was able to figure out the Field Power Source rule so quickly . Dark Yugi explains that it had been bothering him as to why Pegasus was holding the tournament on a large island , but when he sat down at the table and saw the landscape displayed on the table , he figured it out ; the island consists of many micro - climates and each Battle Box reflects the area surrounding it , so monsters get different power sources depending on where the battle takes place . Dark Yugi knows Haga led him to the forest to put his Insects at an advantage . The two continue with the Duel , but Haga laughs to himself that the Field Power Sources do more than increase the ATK of monsters . Haga Summoned " Hercules Beetle " , who gained a 30 % ATK boost from its Field Power Source , raising its ATK from 1500 to 1950 . Dark Yugi didn ' t have any cards in his hand that benefited form either of the terrains , so instead he Summoned " Feral Imp " and equip ped it with " Horn of the Unicorn " , raising its ATK form 1300 to 2000 . He tried attacking " Hercules Beetle " , but " Hercules Beetle " attacked first with " Scissors Boomerang " and destroyed " Feral Imp " , who still had 1300 ATK , dropping Dark Yugi ' s Life Points to 1350 . Haga explained that in the forest , his insects gain initiative and can attack first . Yugi notes that insects are normally weak monsters , but on this field , they ' re formidable cards . Honda is surprised to see Dark Yugi losing to Haga , but Bakura is sure Dark Yugi has a great strategy in store . Dark Yugi is unable to compete with " Hercules Beetle " , so he plays " Griffor " in Defense Mode and ends his turn . Haga believes Dark Yugi is already on the run . Haga Summons " Basic Insect " and equip s it with " Laser Cannon Armor " , raising its ATK from 500 to 2000 , which becomes 2600 due to the Forest . Dark Yugi recognizes this as the combo that Haga used in the last tournament . " Basic Insect " attacks and destroys " Griffor " and Haga laughs that Dark Yugi isn ' t even worth fighting . Dark Yugi plays " Saiga " in Defense Mode . Haga doesn ' t think it ' s worth his time taking out such a low Level monster , so he plays a card face - down in his Spell & Trap Card Zone instead . He laughs to himself , thinking the Trap Card he Set will trigger the moment Dark Yugi announces an attack and will destroy all his monsters . Not prepared to risk an attack , Dark Yugi also spent his turn playing a card face - down . Haga guessed the face - down was a Spell Card , which wouldn ' t be of use . Over the next few turns , Haga Summoned more monsters ; " Pillroach " , " Big Ant " and " Giant Flea " . ( In the English manga , the names on the " Big Ant " and " Giant Flea " cards are mixed - up . ) Dark Yugi worries about this " plague of insects " , but refrains from attacking as it ' s what Haga wants him to do . Instead he plays an unnamed monster in Defense Mode . Haga asks how it feels to be caught in his two - layer trap and laughs that today they will celebrate Yugi ' s death . Dark Yugi draws the " Dark Magician " and plays it in Defense Mode . Haga recognizes this as one of Dark Yugi ' s best cards and instead of " undiscriminating raining doom " on Dark Yugi , like he was planning , he decides to destroy " Dark Magician " first . He declares an attack on " Dark Magician " with " Basic Insect " . Dark Yugi laughs and says " you said attack " , a la how Haga had said it to Ryuzaki . He then reveals that the face - down card he played earlier was " Mirror Force " , which reflects the attack back on all of Haga ' s monsters , destroying them and leaving him with 450 Life Points . Dark Yugi smirks that Haga must have won the last tournament by luck and is maybe the weakest player on the island . Haga Summons " Hercules Beetle " in the Forest ( ATK : 1500 → 1950 ) . Dark Yugi Summons " Feral Imp " ( ATK : 1300 ) and equip ped it with " Horn of the Unicorn " ( ATK : 1300 → 2000 ) Featured Duels . Insector Haga VS Dark Yugi .
