Featured Duels
Duel continues from the previous episode.

Yūya Sakaki vs. Strong Ishijima
Yūya has 400 LP remaining, no cards in his hand, and controls "Entermate Whip Viper" (CG Star 4/1700/900), "Entermate Sword Fish" (CG Star 2/600/600) and "Odd-Eyes Pendulum Dragon" (CG Star 7/2500/2000) all in Attack Position, "Timegazer Magician" (Left Pendulum Scale 8) and "Stargazer Magician" (Right Pendulum Scale 1) in his Pendulum Zones, and no Set cards. Strong Ishijima has 4000 LP remaining, no cards in his hand, and controls "Barbarian King" (CG Star 8/3000 → 5000/1100) in Attack Position and 1 Set card.

Turn 5: Yūya

Yūya activates the effect of "Entermate Whip Viper", switching the ATK and DEF of "Barbarian King" until the End Phase ("Barbarian King": 5000 → 1100/1100 → 5000). He then activates the effect of "Entermate Sword Fish", letting him target and reduce the ATK of a monster his opponent controls by 600 ("Barbarian King" 1100 → 500/5000). "Odd-Eyes Pendulum Dragon" attacks "Barbarian King", but Strong Ishijima activates his face-down "Barbarian Howling" as a "Barbarian" monster he controls is being attacked. This would let him target and return the attacking monster to the hand and inflict damage to his opponent equal to that monster's ATK. Yūya activates the Pendulum Effect of "Timegazer Magician" as a Trap Card that targets exactly 1 Pendulum Monster he controls was activated. This negates the activation and re-Sets the card. Strong Ishijima finds and activates the Action Card "Evasion", which would negate the attack. Yūya activates the Pendulum Effect of "Stargazer Magician" as a Magic Card that targets exactly 1 Pendulum Monster he controls was activated. This negates the effect and Sets the card, while preventing its activation for the remainder of this turn. The attack continues and Yūya activates the effect of "Pendulum Dragon", doubling the battle damage as it is battling a Level 5 or higher monster. "Barbarian King" is destroyed (Strong Ishijima: 4000 → 0 LP).

Yūya Sakaki vs. Yuzu Hīragi
At the start of the Duel, the Field Magic Card "Plain Plane" is activated, as per the rules of an Action Duel. It will allow the players to use Action Cards, but they may only have one in their hand at a time.

Turn 1: Yūya

Yūya Normal Summons "Entermate Discover Hippo" (CG Star 3/800/800).

Turn 2: Yuzu

Yuzu Normal Summons "Aria the Melodious Diva" (CG Star 4/1600/1200). "Aria" attacks "Discover Hippo", but Yūya finds and activates the Action Card "Evasion", which negates the attack. As "Aria" battled without inflicting battle damage, Yuzu activates the effect of "Aria", inflicting 800 damage to Yūya (Yūya: 4000 → 3200 LP).

Turn 3: Yūya

Yūya draws "Timegazer Magician". His hand contains "Timegazer Magician", "Odd-Eyes Pendulum Dragon", "Entermate Sword Fish", "Entermate Whip Viper" and "Wonder Balloon". Yūya activates "Timegazer Magician" (Left Pendulum Scale 8) and "Odd-Eyes Pendulum Dragon" (Right Pendulum Scale 4) in his Pendulum Zones. Yūya attempts to Pendulum Summon "Entermate Whip Viper" and "Entermate Sword Fish" from his hand, but since neither of their Levels are between the two Pendulum Scales (4 and 2 respectively), he cannot Pendulum Summon them and his Duel Disk gives an error. However, Yūya does not realize this requirement, and instead believes that he is unable to Pendulum Summon due to not being "in a pinch" as he was previously.

Turn 4: Yuzu Yuzu draws. As she controls a "Melodious" monster, she Special Summons "Sonata the Melodious Diva" (CG Star 3/1200/1000) from her hand in Attack Position via its own effect. She Advances "Aria" and "Sonata" to Advance Summon "Prodigy Mozart the Melodious Maestra" (CG Star 8/2600/2000) in Attack Position. Yuzu activates the effect of "Prodigy Mozart", letting her Special Summon a Level 4 or lower "Melodious" monster from her hand. She Special Summons another copy of "Aria" (CG Star 4/1600/1200) in Attack Position. "Aria" attacks and destroys "Discover Hippo". (Yūya: 3200 → 2400 LP). "Prodigy Mozart" attacks directly. Yūya, still under his previous belief and noting that he is now in a pinch, attempts to Pendulum Summon "Whip Viper" and "Sword Fish" again, but it fails a second time. The attack continues (Yūya: 2400 → 0 LP).
