Yu - Gi - Oh ! GX - Episode 015 " Courting Alexis " , known as " Duel Tennis of Youth " in the Japanese version , is the fifteenth episode of the " Yu - Gi - Oh ! GX " anime . It first aired in Japan on January 12 , 2005 and in the United States on November 14 , 2005 . Summary . In gym class , the students are playing tennis . Jaden Yuki and Syrus Truesdale are playing against Jasmine and Mindy . Jaden complains that tennis has nothing to do with Dueling , and spikes the ball , which goes off into the adjacent court , right towards Alexis Rhodes . He yells for her to watch out , and the ball is intercepted by someone else , and ends up hitting Dr . Crowler in the face . The boy who intercepeted the ball appears immediately smitten with Alexis and ultimately backs away nervously . Jaden is later called to the infirmary , and is blamed for hitting Crowler with the tennis ball . Ms . Fontaine attempts to defend him , having seen the incident , but Crowler will not listen . He punishes Jaden by forcing him to join the Academy ' s tennis club for a day . Mindy and Jasmine approach Alexis , and reveal that the boy who intercepted the ball is a third - year Obelisk Blue student named Harrington Rosewood , and is the heir to his family ' s company . They attempt to convince Alexis to date him . Syrus enters the room , panicking , and asks where the tennis club meets . They respond they meet out on the courts , and Syrus reveals that Jaden ' s punishment was a day of tennis lessons under the captain of Duel Academy ' s tennis team , who turns out to be Harrington himself . Alexis arrives at the courts , and Harrington assumes she came to see him . She ignores him , however , and reveals to Jaden that she just spoke with Professor Banner , and that someone has recently spotted Chazz Princeton . This enrages Harrington so much that he challenges Jaden to a Duel , with the winner becoming Alexis ' fiancee . Alexis objects , but Jaden accepts the Duel , never turning down a challenge . Alexis contemplates walking out , but stays to see if the rumors that Harrington is as good a Duelist as Zane Truesdale are true . The Duel begins , and Harrington activate s " Service Ace " , which lets him pick a card from his hand . Jaden must guess if it is a Monster , Spell or Trap . If he is wrong , he will take 1500 damage . Jaden guesses Spell , but after some taunting from Harrington changes his answer to Trap . Regardless , it ' s a monster - " Mega Thunderball " , so Jaden loses 1500 LP , while Harrington removes the chosen card from play . Harrington Set s a card to end his turn . Jaden Summons and attacks directly with " Elemental HERO Avian " , but Harrington activates his face - down " Receive Ace " , which negate s the attack and inflicts another 1500 damage to Jaden , though Harrington must send the top three cards of his Deck to the Graveyard . Jaden Sets a card . Harrington activates " Smash Ace " . With this , he reveals the top card of his Deck . If it ' s a monster , Jaden will take 1000 damage . He flips his top card , and it ' s a monster - " Mystical Shine Ball " . However , Jaden activates his face - down " Feather Wind " to negate the activation of " Smash Ace " . Jaden plays " Polymerization " , fusing " Elemental HERO Clayman " and " Elemental HERO Burstinatrix " to Fusion Summon " Elemental HERO Rampart Blaster " . He attacks directly with both of his monsters , tying the Duel at 1000 LP each . Harrington activates " Deuce " , which he can only activate when both players have 1000 LP or less . It essentially changes the rules of the Duel to mimic a round of tennis . LP are now irrelevant , and the first Duelist to inflict damage twice without the opponent inflicting any in between is declared the winner and only one monster may attack per Battle Phase . He then Summons " The Big Server " and uses it ' s effect to attack directly , giving him one point on " Deuce " . A successful attack from " The Big Server " also lets him add a " Service Ace " from his Deck to his hand , while letting Jaden draw a card . He then plays " Service Ace " , with Jaden declaring monster . He is correct , as Harrington reveals another " Mega Thunderball " which is then removed from play . Harrington equip s " The Big Server " with " Giant Racket " , which will let him negate the first attack towards " The Big Server " at the cost of destroying " Giant Racket " . Jaden draws and then plays " De - Fusion " , splitting " Rampart Blaster to Special Summon " Clayman " and " Burstinatrix " . He then plays " Feather Shot " , which will let " Avian " attack once for each monster Jaden has on the field . The first attack is negated by " Giant Racket " , the second destroys " The Big Server " , and the third is a direct attack , meaning Jaden inflicted damage twice , winning the Duel via the effect of " Deuce " . Harrington bursts into tears and runs off . Jaden approaches Alexis , and states that he guesses this means he ' s now her fiancee . He then asks her what that means . She has quite a different response to his question depending on the versions . The episode ends with Harrington staring at the sunset , screeching . Featured Duel : Jaden Yuki vs .

Jaden then activates " Feather Shot " by selecting " Avian " . Now in addition to a normal attack , " Avian " will gain one additional attack for every other monster Jaden control s . Jaden controls two , so " Avian " gains two additional attacks . " Avian " attacks " The Big Server " , but Harrington activates the effect of " Giant Racket " which prevents " The Big Server " from being destroyed and prevents Harrington from taking Battle Damage . " Avian " attacks and destroys " The Big Server " ( Harrington : 1000 → 300 LP ) . " Avian " then attacks directly ( Harrington : 300 → 0 LP ) . Due to the effect of " Deuce " , Jaden automatically wins . Featured cards . The following cards appeared in this episode . Cards in italics debuted here .
