Episode 13

"Magical Sages Galilei & Kepler" (魔導賢者ガリレイ、ケプラー Madō Kenja Garirei, Kepurā), known as "Circus Surprise!" in the Dub version, is the thirteenth episode of the Yu-Gi-Oh! ARC-V anime.

Synopsis
Somehow, Reiji Pendulum Summons and mounts an attack against Yūya. Yūya shows off his ability to Pendulum Summon, something he thought only he could do, and tries to counterattack by Entertainment Dueling, but due to the sheer pressure from Reiji, he's unable to hide his shock. With You Show Duel School's fate on the line, Yūya is extremely anxious.

Yūya Sakaki vs. Reiji Akaba
Duel continues from the previous episode.

Yūya has 4000 LP remaining, 4 cards in his hand, and controls "Entermate Whip Viper" (CG Star 4/1700/900) in Attack Position and 1 Set card. Reiji has 4000 LP remaining, 4 cards in his hand, and controls "DDD Flame King Temujin" (CG Star 6, 6/2000/1500), "DDD Gust King Alexander" (CG Star 7, 7/2500/2000) and "DDD Wave King Caesar" (Rank Star 4, 4/2400/1200) all in Attack Position and no Set cards.

Turn 3: Reiji

"DDD Flame King Temujin" attacks "Entermate Whip Viper", but Yūya activates his face-down "Hippo Carnival", Special Summoning three "Hippo Tokens" (CG Star 1/0/0 each) in Defense Position. Their effects prevent other monsters he controls from being targeted for attacks, so "Temujin" attacks and destroys a "Hippo Token". "DDD Gale King Alexander" attacks and destroys another "Hippo Token". As it it destroyed a monster by battle, the effect of "Alexander" activates, letting it destroy a monster Yūya controls. The third "Hippo Token" is destroyed. "DDD Wave King Caesar" attacks and destroys "Whip Viper" (Yūya: 4000 → 3300 LP). Reiji Sets 1 card.

Turn 4: Yūya

Yūya draws "Timegazer Magician" and subsequently places it (Left Pendulum Scale 8) and "Stargazer Magician" (Right Pendulum Scale 1) in his Pendulum Zones. Yūya Pendulum Summons "Odd-Eyes Pendulum Dragon" (CG Star 7/2500/2000) and "Entermate Fire Mufflio" (CG Star 3/800/800), both from his hand in Attack Position. "Odd-Eyes" attacks and destroys "Temujin", with the former's effect doubling the battle damage as it is battling a Level 5 or higher monster (Reiji: 4000 → 3000 LP). As a Pendulum Monster he controls destroyed an opponent's monster by battle, Yūya activates the effect of "Mufflio", increasing the ATK of "Odd-Eyes" by 200 ("Odd-Eyes": 2500 → 2700/2000) until the end of the Battle Phase and allowing it to attack again, but "Mufflio" itself may not attack. "Odd-Eyes" attacks and destroys "Alexander", with the effect of "Odd-Eyes" doubling the battle damage (Reiji: 3000 → 2600 LP). Yūya finds and activates the Action Card "Wonder Chance", giving "Odd-Eyes" an additional attack. "Odd-Eyes" attacks and destroys "Caesar" (Reiji: 2600 → 2300 LP), with Reiji activating the effect of "Caesar", detaching an Overlay Unit to Special Summon all monsters he controls that were destroyed by battle this turn at the end of the Battle Phase, but during his next Standby Phase, he will take 1000 damage for each one he still controls. The Battle Phase ends and Reiji Special Summons "Temujin" (CG Star 6, 6/2000/1500), "Alexander" (CG Star 7, 7/2500/2000) and "Caesar" (Rank Star 4, 4/2400/1200), all in Attack Position. The effect of "Mufflio" expires ("Odd-Eyes": 2700 → 2500/2000). Reiji activates his face-down "DDD Human Resources", letting him return three "DDD" monsters to his Deck and add two "DD" monsters from his Deck to his hand. He returns "Temujin", Alexander" and "Caesar" to his Extra Deck and adds "DD Magical Savant Kepler" and "DD Magical Savant Galilei". Yūya Sets 1 card.

Turn 5: Reiji

Reiji places "Kepler" (Left Pendulum Scale 10) and "Galilei" (Right Pendulum Scale 1) in his Pendulum Zones. He Pendulum Summons three "DDD Death Great King Hell Armageddon" (CG Star 8, 8, 8/3000/1000 each), all from his hand in Attack Position. The first "Armageddon" attacks "Odd-Eyes", but Yūya finds and activates the Action Card "Miracle", halving the battle damage and preventing "Odd-Eyes" from being destroyed by battle (Yūya: 3300 → 3050 LP). Another "Armageddon" attacks and destroys "Odd-Eyes" (Yūya: 3050 → 2550 LP), which is sent to the Extra Deck. The last "Armageddon" attacks and destroys "Mufflio" (Yūya: 2550 → 350 LP), which is sent to the Extra Deck. Reiji Sets 1 card.

Turn 6: Yūya

Yūya draws "Entermate Partnaga". He Pendulum Summons "Odd-Eyes" (CG Star 7/2500/2000) and "Mufflio" (CG Star 3/800/800) from his Extra Deck and "Partnaga" (CG Star 5/500/2100) from his hand, all in Attack Position. The effect of "Partnaga" activates upon its Summon, allowing Yūya to target a monster he controls and increase its ATK by 300 for each "Entermate" monster he controls. Yūya targets "Odd-Eyes" ("Odd-Eyes": 2500 → 3100/2000). At this point, Yūya envisions a plan to win the Duel: he can attack and destroy an "Armageddon" with "Odd-Eyes"; then he can use the effect of "Mufflio" to give "Odd-Eyes" 3300 ATK and allow it to attack and destroy another "Armageddon", reducing Reiji's LP to 1500; then he can activate his face-down "One Two Jump" as "Odd-Eyes" has destroyed two monsters this turn, which will halve the ATK of Reiji's third "Armageddon" and allow "Odd-Eyes" to attack it for 3600 damage. "Odd-Eyes" attacks and destroys an "Armageddon" (Reiji: 2300 → 2100 LP), which is sent to the Extra Deck. The effects of both remaining "Armageddons" activate; since a monster Reiji controls left the field, they each gain ATK equal to the original ATK of that monster until the end of the turn ("Armageddons": 3000 → 6000/1000 each). At the end of the turn, the effects of both "Armageddons" expire ("Armageddons": 6000 → 3000/1000 each).

Turn 7: Reiji

During Reiji's Standby Phase, "Galilei" and "Kepler" appear to malfunction in their Pendulum Zones, and their Pendulum Effects appear on their cards: "Galilei" doubles its Pendulum Scale ("Galilei": Left Pendulum Scale 1 → 2) and sends to the Graveyard all Pendulum Summoned monsters he controls whose Levels are lower than its Scale, while "Kepler" reduces its Scale by 5 ("Kepler": Right Pendulum Scale 10 → 5) and sends to the Graveyard all Pendulum Summoned monsters he controls whose Levels are higher then its Scale. Since the Levels of the "Armageddons" are higher than the Scale of "Kepler", they are sent to the Graveyard. At this point, Reiji is called away, so he surrenders.
