Featured Duel : Jaden Yuki vs . Thelonious Viper . " Duel continues from the previous episode " . Jaden has 1200 Life Points remaining and controls no cards . Viper has 2100 Life Points and controls " Vennominon the King of Poisonous Snakes " ( 2500 / 0 ) in Attack Position . He also has " Venom Swamp " and " Damage = Reptile " active . Turn 9 : Jaden Jaden draws " Card Trooper " and subsequently Normal Summons it ( 400 / 400 ) in Attack Position . Jaden then activates the effect of " Card Trooper " to send the top three cards of his Deck to the Graveyard ( " Elemental Hero Avian " , " Necro Gardna " and " Elemental Hero Wildheart " ) and increase the ATK of " Card Trooper " by 500 for each card sent this way ( " Card Trooper " : 400 → 1900 / 400 ) . On Jaden ' s End Phase , the effect of " Card Trooper " expires ( " Card Trooper " : 1900 → 400 / 400 ) . At the same time , " Venom Swamp " places a Venom Counter on " Card Trooper " ( " Card Trooper " : 400 → 0 / 400 ) . The third effect of " Venom Swamp " activates , destroying " Card Trooper " . Jaden then activates the last effect of " Card Trooper " to draw one card . Turn 10 : Viper Viper draws . " Vennominon the King of Poisonous Snakes " attacks directly , but Jaden removes from play " Necro Gardna " from his Graveyard to negate the attack . Viper then sets a card . Turn 11 : Jaden Jaden draws " Miracle Fusion " and subsequently activates it to remove from play " Elemental Hero Wildheart " and " Elemental Hero Bladedge " from his Graveyard in order to Fusion Summon " Elemental Hero Wildedge " ( 2600 / 2300 ) in Attack Position . " Wildedge " attacks and destroys " Vennominon the King of Poisonous Snakes " ( Viper 2100 → 2000 ) . Jaden intends for Viper to revive " Vennominon " through its own effect ( which would allow Jaden to create an infinite loop by using " Wildedge " to attack " Vennominon " every time the latter revives itself through its own effect ) , but Viper activates his face - down " Rise of the Sacred Deity " to Special Summon " Vennominaga the Deity of Poisonous Snakes " ( 0 / 0 ) in Attack Position . Due to the first effect of " Vennominaga " , it gains 500 ATK for each Reptile - Type monster in Viper ' s Graveyard . There are currently six ( " Vennominaga " : 0 → 3000 / 0 ) . On Jaden ' s End Phase , " Venom Swamp " places a Venom Counter on " Wildedge " ( " Wildedge " : 2600 → 2100 / 2300 ) . Turn 12 : Viper Viper draws . " Vennominaga the Deity of Poisonous Snakes " attacks and destroys " Wildedge " ( Jaden 1200 → 300 ) . Since " Vennominaga " inflicted Battle Damage , Viper activates the third effect of " Vennominaga the Deity of Poisonous Snakes " , which will give him an automatic win three turns after the activation of this effect . Turn 13 : Jaden Jaden draws " Fusion Recovery " and subsequently activates it to add " Polymerization " and " Elemental Hero Sparkman " from his Graveyard to his hand . Jaden then activates " Polymerization " to fuse " Elemental Hero Sparkman " with " Elemental Hero Necroshade " and Fusion Summon " Elemental Hero Darkbright " ( 2000 / 1000 ) in Attack Position . Jaden then activates " Necro Shot " and equips it to " Darkbright " . Now Jaden , during his Main Phase , can select one monster in Viper ' s Graveyard and remove it from play , but " Necro Shot " will be destroyed after Jaden activates this effect three times . Jaden then activates the effect of " Necro Shot " three times to remove from play three monsters in Viper ' s Graveyard ( two " Venom Serpents " and a " Venom Snake " ) ( " Vennominaga " : 3000 → 1500 / 0 ) . After that resolves , " Necro Shot " is destroyed . Since " Necro Shot " was destroyed through its own effect , Jaden sends " Neo - Spacian Dark Panther " from his Deck to the Graveyard . " Darkbright " then attacks and destroys " Vennominaga the Deity of Poisonous Snakes " ( Viper 2000 → 1500 ) . Viper then activates the second effect of " Vennominaga the Deity of Poisonous Snakes " to remove from play " Venom Snake " from his Graveyard and revive " Vennominaga " ( " Vennominaga " : 0 → 1000 / 0 ) in Attack Position . Jaden then activates the second effect of " Darkbright " to switch it to Defense Position . On Jaden ' s End Phase , " Venom Swamp " places a Venom Counter on " Darkbright " ( " Darkbright " : 2000 → 1500 / 1000 ) . Turn 14 : Viper Viper draws " Snake Rain " and subsequently activates it to discard another " Snake Rain " and send four Reptile - Type monsters from his Deck to the Graveyard ( two " Venom Boas " , " Venom Serpent " , and " Serpentine Princess " ) ( " Vennominaga " : 1000 → 3000 / 0 ) . " Vennominaga " then attacks and destroys " Elemental Hero Darkbright " . Jaden then activates the last effect of " Elemental Hero Darkbright " to destroy " Vennominaga the Deity of Poisonous Snakes " , but it doesn ' t work as " Vennominaga the Deity of Poisonous Snakes " can ' t be targeted or affected by other card effects . Turn 15 : Jaden Jaden draws " Fifth Hope " and subsequently activates it to return Elemental Hero " Clayman " , " Avian " , " Wildedge " , " Bubbleman " , and " Sparkman " from his Graveyard to his Deck and draw three cards ( as Jaden had no cards on his field or in his hand when he activated " Fifth Hope " ) . Jaden ' s hand contains " Elemental Hero Neos " , " Contact " , and " Cocoon Party " . Jaden then activates " Cocoon Party " to Special Summon a Chrysalis monster from his Deck for each Neo - Spacian in his Graveyard with a different name . There are two , so Jaden Special Summons " Chrysalis Mole " ( 700 / 100 ) and " Chrysalis Larva " ( 300 / 300 ) in Attack Position . Jaden then activates " Contact " to send " Chrysalis Mole " and " Chrysalis Larva " to the Graveyard and Special Summon " Neo - Spacian Grand Mole " ( 900 / 300 ) and " Neo - Spacian Flare Scarab " ( 500 / 500 ) in Attack Position . Jaden then uses the effect of " Elemental Hero Necroshade " to Normal Summon " Elemental Hero Neos " ( 2500 / 2000 ) in Attack Position without Tributing . Jaden then Contact Fuses " Elemental Hero Neos " with " Neo - Spacian Grand Mole " and " Neo - Spacian Flare Scarab " in order to Special Summon " Elemental Hero Magma Neos " ( 3000 / 2500 ) in Attack Position . Due to the effect of " Magma Neos " , it gains 400 ATK for each card on the field . There are four ( " Magma Neos " : 3000 → 4600 / 2500 ) . " Magma Neos " then attacks and destroys " Vennominaga the Deity of Poisonous Snakes " ( Viper 1500 → 0 ) . Trivia . The dimension the academy is transported to is the same one Jaden saw in a vision during his duel with Sartorius . Featured cards . The following cards appeared in this episode .
