Yu - Gi - Oh ! - Episode 048 Summary . Yami Yugi is in bad shape , having already lost one of his three Heart Points . If Duke ' s monsters aren ' t stopped , he ' ll be able to close in and attack the last two hearts , winning the game next turn . That means that he ' ll have to surrender his title of " King of Games " to Duke , never duel again , and abandon Joey to a week of servitude and humiliation at Duke ' s feet . Yami turns to the Help Screen provided to him , and he locates the information about his most recent monster , " Thunder Ball " . He sees that it has a powerful effect , but he ' ll need a good roll to make it work . With all his will , he rolls his next three dice , and he sees that not only do two of the dice bear Magic Crests , but they also each have " x2 " multipliers , so Yami gains 4 Magic Crests . With these , he casts " Thunder Ball ' s " ability twice , each time allowing " Thunder Ball " to propel itself in a straight line until it collides with one one Duke ' s monsters , destroying the target . With two resounding crashes , Yami destroys the two most imminent threats to his Heart Points . Duke grudgingly continues the game . He makes no progress on his next turn , but he knows he has to win . He explains to the others that he worked hard to design Dungeon Dice Monsters to be a great game . He sent a description of the game to Maximillion Pegasus , hoping that Industrial Illusions could help sell his game . He was thrilled when he got the response that Pegasus wanted to try out the game himself . Duke flew out to Pegasus ' Duelist Kingdom island just before the tournament began , and he was shocked when Pegasus proceeded to defeat him in their test run , summoning monsters and defeating Duke with ease . But the defeat was worth it because Pegasus enjoyed the game so much , he agreed to have Industrial Illusions produce Dungeon Dice Monsters . With assurances that the contract could be settled after the tournament was over , Duke returned to the mainland satisfied . But his dream is now shattered , because after that tournament , Pegasus has dropped off the face of the earth - - no answers , no contract , nothing . In the English version , Duke accuses Yami of cheating , saying that nobody could beat Pegasus in a fair fight , given Pegasus ' obvious skill , and Duke ' s victory will expose Yami ' s cheating ways . In the Japanese version , Otogi holds Yami responsible for devastating Pegasus and ruining his dream . Either way , Duke is bent on using whatever power it takes to defeat Yami here and now . Yami isn ' t giving up , though , and on his next turn , he manages to gather the dice for a low - level summon . It works , but Duke taunts his new monster , which has been placed so far to the side of the playing field that it ' s no threat to Duke at all . But on his next turn , Duke brings the fight to Yami by summoning a monster in the same portion of the field , using enough Progress Crests to target Yami ' s monster in battle . A power - up effect on Duke ' s monster guarantees a win for Duke , and Yami quickly turns to the Help Screen . Moments before the attack connects , Yami orders his Knight to switch into Defense Mode . When any monster is targeted in battle , one has the option of spending a Defense Crest from the Crest Pool . If so , the damage to the target ' s Hit Points is reduced by the value of the target ' s Defense Points . This still results in a loss of HP for Yami ' s monster , but it survives , and Duke seethes seeing Yami analyzing his game so quickly . On Yami ' s next turn , he activates his Knight ' s ability for a double attack that the " Battle Ox " cannot withstand . The target is destroyed , winning another round for Yami . But Duke only laughs , because his last move did more than summon a new monster . He points out the red squares made by his summoned dice unfolding . The chain of end - to - end squares reached all the way from Duke ' s end of the field to Yami ' s end , and including the squares from Battle Ox ' s die , the path reaches from field ' s left side to the right . The trick is that Yami ' s blue squares can only be built out from existing blue squares , and they cannot cross Duke ' s path . Yami is now trapped with only two small portions of the field in which to summon monsters , while Duke has plenty of space . If all of Yami ' s monsters get destroyed and he has no more space to summon new ones , it will literally be impossible for him to block Duke ' s attacks on his Heart Points . The threat gets worse when Duke starts his next turn , and holds out one of the dice - - a black one . This is a rare die with a special capability , and Duke ' s roll wins a summon with this die . He summons it on a square near his end and his monsters , and it reveals not another monster , but a swirling vortex . Duke explains that a black die can summon a " Warp Vortex " , and when two of these are in play , a monster that enters one vortex will teleport to the other one . Furthermore , Duke ' s pathway reaches so far into Yami ' s side of the field that one more Warp Vortex in that spot will let Duke move his monsters to charge at Yami ' s Heart Points with very little effort . Yami tries to prepare for it , and he uses some of his precious remaining space to summon the upper - level monster , " Strike Ninja " . Then it ' s Duke ' s turn again , and he gloats to see that he ' s got the second black die already . With a vengeance , he rolls . . . but he doesn ' t get the summon . Then it ' s Yami ' s turn again , and with a shock , he gets an idea . Smiling , he shows Duke his newest opportunity - - a black die of his own . He rolls , and the summon works . Yami summons a " Warp Vortex " and sends his " Strike Ninja " to it immediately . This monster has the power to move three times as quickly as a regular one , and with the power of the " Vortex " , it reappears deep in the heart of Duke ' s territory . One attack from the ninja wipes out the low - level monster nearest Duke ' s podium , and Yami ends his turn . Duke is exposed , but his next roll doesn ' t let him do anything . Yami rolls again , and he gets enough Progress Crests for Strike Ninja to charge the rest of the way and attack . With a burst , one of Duke ' s Heart Points is gone . Duke is now more angry than ever , and he rolls , seeing with a rush that he ' s gotten a strong summon . He uses it right next to " Strike Ninja " , summoning " Orgoth the Relentless " , which he claims is his ace monster . He begins this comeback with an ability that taps into his Crest Pool for a permanent power boost to " Orgoth ' s " ATK . " Orgoth " marches to his victim , and Yami knows that defending won ' t help against this attack . The giant sword swings down , crashing through with a great explosion . But when the smoke clears , " Strike Ninja " is still standing . Duke is thunderstruck , and Yami explains the latest effect he learned : " Strike Ninja " can draw on Trap Crests to gain the ability to dodge attacks , taking no damage . Duke is now angrier than ever , but he can do nothing as Yami takes his next turn and launches another attack with " Strike Ninja " . It hits , putting Duke down to only one Heart Point left . Duke takes his turn , and " Orgoth " goes in for another attack . Yami Yugi realizes he has no Trap Crests left , and this time , the slash hits home , wiping out " Strike Ninja " . Duke turns to his nemesis , muttering that it was close , and Duke may be one Heart Point behind , but now he has " Orgoth " ready to finish the job . Furthermore , Yami Yugi ' s recent plays have all but covered his territory - - there aren ' t as many as three open squares in a row anywhere on his side . Because of this , Duke knows that all he has to do is plow through the three minute monsters Yami Yugi has left , and there ' ll be nothing to stop him from winning . And with so much on the line , Yami Yugi can ' t even think about what will happen if he loses . Featured Duels : Duke Devlin vs . Yami Yugi , Part 2 .
