Yu - Gi - Oh ! ARC - V - Episode 050 " Dueling Declan " , known as " Lancers - The Chosen Warriors " in the Japanese version , is the fiftieth episode of the " Yu - Gi - Oh ! ARC - V " anime . It first aired in Japan on April 5 , 2015 and in Canada on July 22 , 2016 . It became available with official subtitles via Crunchyroll on December 20 , 2016 Summary . Yuya asks Declan what he means by the fact that the Battle Royal was a selection exam for the Lancers , and he desperately tells Declan to answer him . Did Declan know that the Duelists from the Fusion Dimension were going to show up from the start ? Declan admits that he knew of the imminent arrival of the Obelisk Force , which was why he changed the Junior Arc League Championship quarter finals to a Battle Royal in Paradise City . He intended to have them face and fend off the enemy invasion . Yuya is shocked , and he asks why the Junior class were the ones Dueling rather than the Senior or Pro divisions . Sylvio grimly explains that the Senior class were fighting too , but they were all wiped out save one guy . Gong asks " Wiped out " and Sylvio states that that was why Sylvio was sent out . Declan declares that just as he expected , they succeeded in repelling Duel Academy . They are truly their anti - Duel Academy warriors , and they have shown power worthy of the title " Lancers " . " Stop messing around ! " Yuya yells . For something like that , Reed and Trout , and everyone were turned into cards . He remembers seeing Reed and Trout being sealed into cards , and sadly whispers that Zuzu was as well before beginning to cry . Aura whispers , " Darling " and Celina looks at Yuya sadly . Yuya sobs that it is Declan ' s fault for what happened to Zuzu and the others . Celina speaks up ; claiming that Declan is not at fault ; if Zuzu was defeated by Duel Academy then the fault is hers . Gong asks her what she means , and before that , who is she ? Celina introduces herself , explaining that she is a Duelist of Duel Academy . Sylvio is immediately suspicious of Celina , asking if that means that she ' s the enemy . Dennis sadly laments to himself that Celina had to go ahead and say it . He was planning to bring her back to Duel Academy after things had calmed down , but now that doesn ' t look like it ' ll be possible . Sylvio asks why the enemy is with them , and wearing Zuzu Boyle ' s clothes too . He asks if Celina is a spy , sent to gather information while disguised as Zuzu Boyle , and he decides that that ' s got to be it . Moon steps in front of Celina , and Sylvio angrily asks him why he ' s getting in Sylvio ' s way and protecting the enemy . Moon stiffly replies that it ' s by the orders of his client , and Sylvio asks him what he ' s talking about . Declan declares that Celina isn ' t a spy , but she was chased here by Duel Academy . Celina confirms it , explaining that the Obelisk Force came here chasing after her . She ' s certain that Zuzu was mistaken for her and … " Mistaken for you ? " Gong asks . Aura asks why Zuzu and Celina even switched clothes in the first place . Moon steps aside as Celina explains that it was in order to meet with Shay . Everyone looks at Shay , as Celina explains that Zuzu had told her to go to Shay in person and ask exactly what happened in the Xyz Dimension . That ' s why Zuzu went out as bait , in order to draw the Obelisk Force away from her . Yuya gasps that she can ' t mean … Declan muses that he sees , so that ' s what it was . He adjusts his glasses , stating that they all won and survived , and what they need is that strength . Yuya begins clenching his fists as Declan continues by claiming that instead of mourning those who were defeated , they should be proud that they have overcome such strong Duelists . Yuya yells at Declan to shut up , and mutters that if he hadn ' t had them fight , then Zuzu … He cuts off his sentence and yells at Declan to give everyone back , launching a punch . Declan catches the younger boy ' s fist with ease , and he tells Yuya that if he calls himself a Duelist , then he should express his anger not through his fists , but through his Duels . He throws Yuya backwards , and Yuya replies that he will . For Zuzu and all of their comrades who were sealed in cards , he ' ll make Declan grovel . Declan adjusts his glasses , replying that it ' s fine by him . If he loses , he ' ll repent until Yuya is satisfied . In the Leo Corporation observation room , Henrietta Akaba and Riley Akaba , the latter holding his Youth League trophy , ascend on the lift to where Claude is waiting . When she sees Declan on the main screen , Henrietta runs forwards , asking why Declan is there , but she is cut off by Declan explaining to Yuya and the others that they are not aware of their true mission yet , nor why he decided to create the Lancers . He explains that the Lancers were created to save their home from the same tragedy that befell the Xyz Dimension . Raising his hand , he declares the activation of the Action Field " Neo Heartland City " . Heartland City materializes around the assembled group , and Celina is the first to recognize it . Shay confirms it , his … their … and Yuya gasps , before Shay yells , " Homeland ! " Yuya hangs his head as Declan asks Shay to accept Zuzu Boyle ' s wish and tell them exactly what happened in Heartland . But Shay closes his eyes and tightens his mouth , refusing to answer , and Declan muses that it seems like he ' s stirred up some indescribable disgrace . Then he will say it , and he explains that just as the Fusion Dimension ' s Duel Academy attacked the Junior Duelists in the Battle Royal , they did the same to the Xyz Dimension . Yuya interrupts , begging Declan to stop . He hugs himself , begging Declan to please stop and walks forwards , prompting cries from Gong and Aura . Ignoring Yuya ' s pleas , Declan explains that by the time Duel Academy came here , they had already finished with the Xyz Dimension … Yuya finally yells at Declan to stop , and Yuto speaks alongside him as they yell that they won ' t let Declan say another word . Yuya declares that he ' ll beat Declan now and make him repent , and both of them yell , " Duel ! " Yuya takes the first turn , immediately using the Scale 4 " Performapal Trump Witch " and the Scale 8 " Xiangsheng Magician " to Set the Pendulum Scale . With this he can simultaneously Summon monsters from Level s 5 to 7 . He chants , " Swing , pendulum of the soul ! Draw an arc of light across the aether ! Pendulum Summon ! Come , my monsters ! " He Pendulum Summons both " Stargazer Magician " and " Performapal Splashmammoth " in Defense Position . Dennis is surprised to see a Pendulum Summon so early , and he comments that Yuya is going full force right from the start . Yuya ends his turn . Shay turns to Celina and asks what Zuzu told her , what would someone from Duel Academy want to know ? Celina doesn ' t reply . Declan declares his turn and draws " D / D Berfomet " , and then he activates the effect of the " D / D Swirl Slime " in his hand , fusing it with " D / D Berfomet " . He chants , " Arcane swirl that takes on all forms , engulf the grotesque god and give birth to a new king ! Fusion Summon ! Be born ! D / D / D Flame King Genghis ! " Gong gasps " Genghis ' " name , recognizing the Fusion Monster that Declan using in his previous Duel with Yuya . Aura is surprised , asking if Yuya has already Dueled Declan . Gong confirms that he has , at You Show Duel School . Dennis asks who won that time , and Gong explains that the match ended before it could finish , but had it continued … Declan continues his turn , Normal Summon ing the Tuner monster " D / D Nighthowl " . " Nighthowl " appears and screeches , and Aura and Dennis are shocked to see a Tuner monster . Gong confirms that Declan doesn ' t just use Fusion Monsters , as Declan activates the effect of " Nighthowl " . Since it was Normal Summoned , he can Special Summon a " D / D " monster from his Graveyard and make its ATK and DEF zero . Purple energy forms in " Nighthowl ' s " maw and it releases " D / D Berfomet " . Then Declan tunes the Level 4 " Berfomet " with the Level 3 " Nighthowl " , chanting " Howls that tear through the night , with the swiftness of a gale give birth to a new king ! Synchro Summon ! Be born ! Level 7 ! D / D / D Gust King Alexander ! " Dennis is shocked that Declan can Synchro Summon as well . Declan then proceeds to activate the effect of " Flame King Genghis " , who raises its sword and its flames intensify as Declan explains that when he has Special Summoned another " D / D " monster he can Special Summon a " D / D " monster from his Graveyard . He revives " D / D Swirl Slime " , and then he activates the effect of " Gust King Alexander " since a " D / D " monster was Special Summoned , allowing him to Special Summon a Level 4 or lower " D / D " monster from his Graveyard . The winds surrounding " Alexander " intensify and Declan revives " D / D Berfomet " again and then activates its effect , doubling the Level of " Swirl Slime " . " Swirl Slime " increases from Level 2 to Level 4 , and Gong observes that now Declan has two Level 4 monsters . Realizing what Gong is implying , Dennis gasps , don ' t tell him that Declan can use more than just Fusion and Synchro Monster s . With a smile , Declan overlays the Level 4 " Berfomet " and " Swirl Slime " , and he chants , " In order to subjugate all that resides in this world , now , descend onto the peak of the world ! Xyz Summon ! Be born ! Rank 4 ! Wave King Caesar ! " Dennis swallows , shocked that Declan can Summon Fusion , Synchro and Xyz Monster s . Sylvio asks Dennis if he ' s from LID and he didn ' t know that much ; Declan Akaba is famous for mastering the different Summoning methods . Dennis asks if Sylvio knew , and Sylvio admits that it ' s his first time seeing it . Yuya explains that it ' s not just them ; Declan can Pendulum Summon as well . Sylvio crossly states that even he knows that too , but Yuya then explains that Declan can likely use what is beyond that , much to Sylvio ' s confusion . As Declan and Yuya stare one another down , Shay asks Celina if she really came here to fight him , and he asks why . Celina explains that she thought that if she defeated the remnants of the Xyz Dimension , then she would be able to prove her abilities to the Professor , Leo Akaba , who hadn ' t sent her to the front lines . That was what drove her to come to this dimension , but … She explains that she believes that Duel Academy ' s fight to unite the dimensions is justice , and she was proud to fight for that cause . But Zuzu told her that her comrades who went to the Xyz Dimension did not act as if they were preserving justice . Instead they acted as if it was a hunting game , smiling and laughing as they attacked people . She desperately asks Shay if what Zuzu told her is true , and Shay replies that it is . He remembers the attack as he explains that they continued to hunt defenseless people as if it were a game . Declan declares his Battle Phase , attacking the Defense Position " Stargazer Magician " with " D / D / D Gust King Alexander " . " Alexander " swings its blade , sending a blade of wind at " Stargazer " and knocking him into a cylindrical building . The building begins to fall as " Stargazer " disintegrates . Declan then attacks the Defense Position " Splashmammoth " with " D / D / D Wave King Caesar " . " Caesar " swings its massive greatsword , sending a surge of water through the ground that blasts " Splashmammoth " off the plaza where they are Dueling , leaving a trail of flames in its wake . Then he attacks directly with " D / D / D Flame King Genghis " , and " Genghis " charges , swinging its broadsword . Yuya is blasted off his feet and down the stairs leading to the plaza , his LP falling to 2000 . The sight of the flames brings back painful memories for Shay : " Ancient Gear Knights " and " Double Ancient Gear Hunting Hound s " attacking Heartland under the command of red jacketed Duel Academy students , who laugh monstrously with glowing red eyes . Moon watches as Shay explains to a horrified Celina that even now the laughter of the Duel Academy students is carved into his eyes and ears and he will never be able to forget it . In the Leo Corporation observation room , Henrietta proudly claims that it ' s as expected of Declan ; now his opponent has an empty field and he even cut his opponent ' s LP in half . Declan Set s a card and ends his turn , commenting that he suspects that Yuya , who struggles up the stairs , has expected everything that has happened so far . Henrietta is shocked , and Declan quotes from their last Duel , " From here on is the real deal . " That ' s what Yuya is thinking , isn ' t it ? He comments that Yuya has already found what lies beyond Pendulum Summoning , and he tells him to use it against Declan ; the new power that he has acquired . Yuya climbs the last step , commenting that Declan sees through everything , doesn ' t he , as expected of a prodigy Duelist . Did he foresee the outcome of the Battle Royal with that brain of his too , how many would fall , how many would survive ? Is he satisfied that it ended just as he expected ? Declan doesn ' t respond , and Yuya yells that they are not his puppets . Yuya remembers Reed and Trout , everyone who was turned into cards , they were all humans with their own hearts . Even Zuzu . Aura closes her eyes and sadly whispers , " Darling " . Yuya sadly explains that Zuzu was always by his side and encouraging him . When he would be mocked for his father and bullied , she was always there for him . Because Zuzu was there , the reason he found what was beyond Pendulum Summoning was because he saw Zuzu trying her hardest to become stronger . That ' s why he will also … He declares his turn and he draws " Odd - Eyes Pendulum Dragon " . He declares another Pendulum Summon with the currently Set " Performapal Trump Witch " and " Xiangsheng Magician " , bringing " Stargazer Magician " and " Performapal Splashmammoth " back from his Extra Deck , and Summoning " Odd - Eyes Pendulum Dragon " from his hand . Yuya activates the effect of " Splashmammoth " , allowing him to use it as Fusion Material to Summon a Fusion Monster , at the cost of banishing " Splashmammoth " . " Splashmammoth " inflates and then pops the balloon over the tip of its trunk , releasing several bubbles , and Yuya declares that he is fusing it with " Odd - Eyes Pendulum Dragon . He chants , " Dual - eyed dragon , become one with the blizzard behemoth and give birth to a new power ! Fusion Summon ! Come forth ! Ferocious dragon with luminous feral eyes ! Beast - Eyes Pendulum Dragon ! " Gong is excited to see the Fusion Dragon that Yuya first Summoned in their Duel . Yuya activates the effect of " Stargazer Magician " , allowing him to Special Summon a Pendulum Monster that left the field , and he returns " Odd - Eyes Pendulum Dragon " to the field . Then he activates the Pendulum Effect of " Performapal Trump Witch " , allowing him to use monsters he controls as Fusion Materials for a Fusion Summon . " Trump Witch " releases her suits symbols , causing both " Odd - Eyes " and " Stargazer " glow and lift into the air , and Yuya chants , " Wielder of mysterious powers , become a bright light in the eye of the dragon ! Fusion Summon ! Come forth ! Arcane dragon - wielder of ancient magic ! Rune - Eyes Pendulum Dragon ! " Aura gasps that this time it ' s the Fusion Dragon that Yuya used against her ( Aura ' s reaction to Yuya summoning " Rune - Eyes " is cut from the dub . ) . Yuya explains that " Beast - Eyes " and " Rune - Eyes " are monsters that he was able to Summon thanks to the hint that he got from Zuzu . He recounts learning from Sora that Zuzu was going to be training to learn Fusion Summoning from him to defeat LID , and grits his teeth at the memory of Zuzu . Oh ? Declan asks . From Sora Perse ? While Declan didn ' t know that specifically , he ' s surprised that Zuzu learned Fusion Summoning from a member of Duel Academy . Yuya is shocked that Declan knew that Sora was from Duel Academy , and Declan explains that Sora ' s Fusion Summoning energy was on a different level from those at LID . He muses that he sees , so that power in turn affected Yuya , giving him the power to call upon a new dragon . Yuya is shocked at the prospect of Sora ' s power affecting him , asking Declan if he ' s saying that his ability to call out " Rune - Eyes " and " Beast - Eyes " is a result of Duel Academy ' s power . Declan replies that it ' s just a single hypothesis that hasn ' t been proven yet , and Yuya states that he was motivated by Zuzu wanting to become stronger to defeat LID , that ' s why he will beat Declan no matter what . He explains that since " Rune - Eyes " used " Stargazer Magician " as its Fusion Material , it can attack three times . A triangle of energy attaches itself to the points in the ring on " Rune - Eyes ' " back , and Yuya tells it to attack " Flame King Genghis " , " Gust King Alexander " and " Wave King Caesar " . " Rune - Eyes " blasts " Caesar " , " Genghis " and " Alexander " with " Triple Spiral Sky Shot " , destroying them all and reducing Declan to 1900 LP . Celina gasps that Shay ' s sister really was kidnapped , and Shay confirms it , but he asks Celina why she looks so much like Lulu , and Celina finds herself unable to answer ( In the dub , Shay states it hurts to look at Celina because she looks exactly like Lulu , causing her to gasp . ) Declaring the final blow , Yuya attacks directly with " Beast - Eyes Pendulum Dragon ' s " " Blazing Spiral Storm " . " Beast - Eyes " launches its bestial plume of flames , and both Aura and Gong observe that if Declan takes the 3000 ATK of " Beast - Eyes " , then the Duel is over . Even Declan seems to be shocked as the attack hits and he vanishes behind a cloud of smoke . Everyone believes that Yuya has won , but Declan steps out from the smoke cloud , his LP still at 1900 . He explains that he activated the Trap Card , " D / D / D Contract Change " , which reduced the damage to zero by banishing the " D / D / D " monster from his Graveyard with the highest ATK ; " Alexander " . Aura gasps , " No way " , and Gong whispers Yuya ' s name . Yuya curses as Declan explains that in addition , he can add a Level 4 or lower " D / D " Pendulum Monster from his Deck to his hand , and he adds " D / D Savant Kepler " . He explains to Yuya that he has come to understand that the reason that he found the path from Pendulum Summoning to Fusion Summoning is because of Yuya ' s strong feelings towards Zuzu Boyle . But if Yuya only evolves through strong emotions , then he cannot win at Dueling . Yuya is shocked , and Declan reminds him that the Lancers are a squad intended to fight in real combat , so Yuya will do well to remember that in a real battle such unstable emotions could cost him his life . Yuya retorts that he doesn ' t intend to be part of the Lancers , and Declan asks if Yuya doesn ' t want to save Zuzu . Everyone gasps in shock , and Yuya asks if Declan is saying that Zuzu is alive . Celina asks if Declan means that Zuzu was captured by the Obelisk Force ; is Declan saying that he saw that ? Dennis panics , wondering if Declan saw Yuri abducting Zuzu , and he ruefully thinks that his own identity may be in danger . Declan urges Yuya to end his turn , since next it is his turn to show Yuya his true strength . Yuya ' s lip trembles in anger , and Declan tells Yuya that if he wants to defeat Duel Academy and save Zuzu , then Yuya must defeat Declan first . Yuya looks up angrily at Declan and they stare one another down . Featured Duel : Yuya Sakaki vs . Declan Akaba .
