Episode 37

"The Destiny that Starts Moving" (きす Ugokidasu Unmei), known as "A Dark Reflection" in the Dub version, is the thirty-seventh episode of the Yu-Gi-Oh! ARC-V anime.

Synopsis
Sora disappears from the Duel field and all that's left are the three duelists: Yūya, Yūto, and the mysterious Yūgo. Yūto challenges a duel against the "The Fusion Side's Agent", Yūgo. However, Yūto finds himself being constantly hunted down by Yūgo, who is an expert user of Synchros. Yūya tries to stop the two of them, but could not. An impactful ending awaits them all at the end of this Duel!

Yūto vs. Yūgo
Turn 1: Yūgo

As he controls no monsters, Yūgo Special Summons "Speedroid Beigomax" (CG Star 3/1200/600) from his hand via its own effect. He Normal Summons "Speed Roid Three-Eyed Dice" (CG Star 3, 3/300/1500). Yūgo then tunes the Level 3 Tuner monster "Tri-Eyed Dice" with the Level 3 "Beigomax" to Synchro Summon the Level 6 "High-Speedroid Magical Sword Dama" (CG Star 6/2200/1600) in Attack Position. He activates its effect; once per turn, he can banish 1 "Speedroid" monster from his Graveyard and inflict 500 damage to his opponent. He banishes "Beigomax" (Yūto: 4000 → 3500). Yūgo Sets a card.

Turn 2: Yūto

Yūto Normal Summons "Phantom Knights Rugged Glove" (CG Star 3/1000/500). Since he controls a Level 3 "Phantom Knights" monster, he Special Summons " Phantom Knights Silent Boots" (CG Star 3/200/1200) from his hand via its own effect. He overlays his two Level 3 monsters to Xyz Summon "Phantom Knights Break Sword" (Rank Star 3/2000/1000/2 ORU) in Attack Position. Since "Rugged Glove" was used as an Xyz Material for the Xyz Summon of "Break Sword", it gains 1000 ATK until the end of this turn ("Break Sword" 2000 → 3000). "Break Sword" attacks and destroys "Sword Dama" (Yūgo: 4000 → 3200). Yūto Sets a card.

Turn 3: Yūgo

Yūgo activates "Speed Rebirth", which allows him to Special Summon a "Speedroid" monster from his Graveyard, but he cannot Normal Summon/Set this turn. He Special Summons "Sword Dama". "Sword Dama" attacks "Break Sword", but Yūto activates his face-down "Phantom Sword", which increases the ATK of a "Phantom Knights" monster he controls by 800. Yūgo activates his face-down "Speed Turn", as he controls a "Speedroid" monster. He can change an Attack Position monster to Defense Position and it loses 500 DEF. "Break Sword" switches to Defense Position ("Break Sword" 1000 → 500). The attack continues, but Yūto activates the other effect of "Phantom Sword", which allows him to send it to the Graveyard to prevent the destruction of "Break Sword". "Sword Dama" inflicts piercing battle damage via its effect (Yūto: 3500 → 1800). Yūgo Sets a card.

Turn 4: Yūto

Yūto switches "Break Sword" to Attack Position. He Normal Summons "Phantom Knights Dusty Robe" (CG Star 3/800/1000) and activates its effect, which allows him to change it to Defense Position and increase the ATK of a "Phantom Knights" monster he controls by 800 until the end of the turn. He selects "Break Sword" for this effect ("Break Sword" 2000 → 2800). "Break Sword" attacks and destroys "Sword Dama" (Yūgo: 3200 → 2600). Yūto Sets a card.

Turn 5: Yūgo

Yūgo draws "Hidden Shot". He Normal Summons "Speedroid Double Yoyo" (CG Star 4/1400/1400). As it was Normal Summoned, Yūgo activates its effect, which lets him Special Summon a Level 3 or lower "Speedroid" monster from his Graveyard. He Special Summons "Tri-Eyed Dice". Yūgo then tunes the Level 3 Tuner monster "Tri-Eyed Dice" with the Level 4 "Double Yoyo" to Synchro Summon the Level 7 "Clear Wing Synchro Dragon" (CG Star 7/2500/2000) in Attack Position. "Clear Wing" attacks and destroys "Break Sword" (Yūto: 1800 → 1300). The effect of "Break Sword" activates, as it left the field; Yūto can Special Summon all the monsters that were attached to it as Overlay Units and their Levels become 4. Both "Rugged Glove" and "Silent Boots" are Special Summoned. Yūgo activates "Hidden Shot" from his hand, which lets him banish a "Speedroid" monster from his Graveyard to destroy a monster his opponent controls. Yūgo banishes "Double Yoyo" and destroys "Dusty Robe".

Turn 6: Yūto

Yūto overlays his two Level 4 monsters to Xyz Summon "Dark Rebellion Xyz Dragon" (Rank Star 4/2500/2000/2 ORU) in Attack Position. He activates its effect, detaching an Overlay Unit to halve the ATK of a Level 5 or higher monster Yūgo controls and add that amount to its own ATK until the end of this turn. Yūgo activates the effect of "Clear Wing", as a monster effect that targets a Level 5 or higher monster(s) on the field was activated; he can negate that monster's effect and destroy that monster. Yūto activates his face-down "Phantom Wing", which allows him to negate the destruction of a monster he controls and increase its ATK by 500 ("Dark Rebellion" 2500 → 3000). He is about to attack but after Yūya breaks him out of Berserk Mode, he chooses not to.

Turn 7: Yūgo

Yūgo draws and subsequently Normal Summons "Speedroid Shave Boomerang" (CG Star 4/2000/0). He activates its effect, which allows him to change it to Defense Position, and then have a monster on the field lose 300 ATK. Yūgo targets "Clear Wing", but its effect activates, as it was targeted by a monster effect. Yūgo negates the effect of "Shave Boomerang" and destroys it, then "Clear Wing" gains ATK equal to the destroyed monster's ATK, until the end of this turn ("Clear Wing" 2500 → 4500). "Clear Wing" attacks and destroys "Dark Rebellion" (Yūto: 1300 → 0).
