I'm in Yu-Gi-Oh!, but I'm also in Machine Ascension.

"And right after I used [Tune], the card I sent from the top of my deck to the graveyard was a Level 1 Machine-Type monster, so I will immediately Special Summon it to the field in Guard Position—"

"Come forth, [Jet Synchron]!"

Soon, in the instant the small warrior wearing a white scarf in the field of Yufengchang waved his leather-armored arm to activate his effect, the only [Monster] card in his graveyard was immediately brought to the field under the brilliance of the activated effect.

In an instant, right next to the main monster zone in the front field, a [Machine-Type] Synchro monster card appeared, just as everyone had been watching, resembling a jet engine soaring through space:

Jet Synchronizer

[Race: Mechanical]

[Attribute: Fire]

[Star rating: 1]

[Attack power: 500]

[Defense: 0]

...

But just as this much-anticipated [Machine-Type] monster card was Special Summoned from the Graveyard, a glance at the two monster cards on the field revealed that, although their auras were completely different, they both had [Synchronizer] as their card name, clearly belonging to the [Tuner] genus.

Among the spectators, those who had been eagerly anticipating Yuu's upcoming [Synchro] maneuver were suddenly filled with confusion.

"But—although you have two monster cards on your field, they are both Tuners, right? Doesn't that mean it doesn't meet the basic requirement of a Synchro Summon: a Tuner + a non-Tuner material?"

"...So even then, we still can't perform a [synchronization] operation, right?!"

Amidst the skepticism of the crowd, the boy with the "jellyfish head," Yuki Jaden, leaned back with his hands behind his head, looking completely at ease.

"Well... if it's about Yuuka-senpai playing cards... I advise you all to completely relax... this powerful legendary duelist might be hiding a hidden trait called 'Never Losing'!"

As Jaden Yuki exuded a calm and confident smile, Asuka Tenjouin, the girl beside him, nodded in agreement, though her worry was more pronounced.

...

At that moment, after performing two summons/special summons in succession, Yufeng immediately smiled and played a card from his hand onto the field:

"That's right, two Tuners cannot perform a Synchro Summon—"

"But it doesn't matter!"

"At this moment, I will activate the effect of the second core monster card in the [Junk Synchron] deck construction, besides [Junk Synchron], [Doppelganger Warrior]: When a monster is Special Summoned from your Graveyard, you can activate this effect. Special Summon this card from your hand."

Soon, with the release of the Level 2 [Effect Monster] card by Youfeng, another vortex of power reappeared next to the two monster cards in Youfeng's main monster zone in the front row. Then, a powerful warrior wielding a machine gun, so powerful that it left an afterimage, was immediately summoned to the field.

【Doppelganger Warrior】

[Race: Warrior]

[Attribute: Dark]

[Star rating: 2]

[Attack power: 800]

[Defense: 800]

...

"【Abolished Version 2】..."

"One 3-star card and one 2-star card, although they're from Senior Youfeng..."

"But at this moment, it doesn't show any strength whatsoever..."

At that moment, looking at the two monsters in front of Youfeng, Ed Phoenix, a professional player who had been watching from a corner of the duel arena since the start of the duel, frowned and asked with slight doubt:

"While Yuuka-senpai is indeed an unparalleled duelist, is he really, as Saiou said, an innovator and a change-maker with powerful creative abilities?"

"...the power...even has the potential to alter the entire trajectory of destiny..."

Soon, accompanied by Edward's murmured words, Yufeng immediately took a deep breath, reached into his silver-white Duel Disk, and this time took out his entire Extra Deck, drawing out a monster card that best embodied the essence of the "Junk Deck" and playing it onto the field:

"Then come on!"

"I'll use the 3-star tuned [Scrap Synchron] and the 2-star [Doppelganger] in the arena as Synchronization materials for star-level tuning—"

"3+2=5!"

"Synchronization Summon - Rank 5! [Bouncing Warrior]!"

Soon, accompanied by Yufeng's powerful voice, a bright white circular [Synchro] channel flashed rapidly in the field. The two monster cards Yufeng specified immediately rose into the air and entered the [Synchro] channel. After a flash of white light, they disappeared.

A powerful mechanical armored warrior monster, clad in gray armor and with massive shoulder pads resembling two catapult runways on either side of its body, immediately appeared:

Catapult Warrior

[Race: Warrior]

[Attribute: Earth]

[Star rating: 5]

[Attack power: 1000]

[Defense: 1500]

...

"Hmm... Could this monster be the [Catapult Turtle] PLUS version?!"

Soon, upon seeing the two catapult runways on the shoulders of this powerful and imposing machine, resembling those carried by a catapult turtle, everyone looked at Youfeng with suspicion.

At the same time, seeing the monster that could almost cripple him appear, Saiou Takuma took a small step back. However, in the instant of his physiological reaction to dodge, he immediately recognized the monster card that Yuufu had just summoned and sneered:

"Hehehe~ That's right, that's it... The direction that fate has pointed out has begun to arrive!"

Soon, a tiny white light flashed in the eyes of the young duelist with long, purplish-red hair, and a smug smile appeared on his lips, as if to say, "Everything was going as planned."

This sudden change in the situation instantly made the expression of the "jellyfish-headed" boy, Yuki Judai, become extremely serious, and he immediately clenched his fists:

"This atmosphere, which is closer to a dark duel, is definitely not an ordinary entrance exam!"

Amidst Jaden Yuki's sighs, Asuka Tenjouin, the long-haired girl beside him, also shook her head with a similarly tense and helpless expression:

"...You only realized it now...Jūdai...this guy seems to harbor some kind of extremely aggressive purpose!"

...

At the same time, gazing at the other person's excited expression, You Feng immediately and slowly shook his head:

"In that case, I will activate the effect of the [Doppelganger Warrior] that I was sent to the Graveyard as [Synchro] material: This effect can be activated if this card is sent to the Graveyard as Synchro material. Special Summon 2 [Doppelganger Tokens] Warrior-Type/DARK/Level 1/ATK/DEF 400 to your field in Attack Position."

Soon, accompanied by Youfeng's calm tone, two identical chibi-style [Doppelganger Warriors] appeared again in the two main monster zones of the arena.

After activating his Graveyard Effect to Special Summon a monster from his Token Deck, Yuufu once again reached for his silver Duel Disk, drawing from his Extra Deck a Level 2 silver Synchro monster and issuing the Synchro Summon command:

"Then I can use this 1-star [Doppelganger], along with the 1-star [Tuner] [Jet Synchron] on the field, as [Sync Material] to upgrade its star level!"

"1+1=2!"

"Let our gathered prayers lead to a horizon of new speed, and become a path of shining light! Synchro Summoning, the power of hope, Synchro Coordinator, Formula Synchron!"

Soon, as the two monster cards on the field rose into the air as Synchro Material and entered the Synchro Sluice, a huge engine roar echoed across the field. A Machine-Type Synchro monster, resembling an F4 Formula 4 race car, immediately drove into the main monster zone in front of the field.

Formula One Synchronizer

[Race: Mechanical]

[Attribute: light]

[Star rating: 2]

[Attack power: 200]

[Defense: 1500]

...

Almost simultaneously, everyone was taken aback when they saw Youfeng suddenly perform another [Synchronization] operation. Then, their expressions gradually became more interesting:

"This...it actually works?!"

"While many cards could create tokens before... it's surprising that tokens can be used as Synchro materials..."

"That would be an incredible money-maker!"

Soon, amidst the sighs of the crowd, Jaden Yuki, who was more sensitive to card battles, instantly grasped the essence of the Yuuki Wind [Waste 2] deck. Stroking his chin, he murmured in astonishment:

"Hmm... if that's the case... if [Scrap Synchron] activates its effect to revive a monster in the Graveyard, and then [Scrap II] appears, and after the Synchron is completed, I can also gain 2 free 1-star materials..."

"If this combo can be used repeatedly, then the resources that can be built... will be terrifying..."

...

At the same time, accompanied by Jaden Yuki's sigh, Yuuki first pointed at the newly Synchro Summoned monster and activated its effect:

"First of all—you can activate this effect when this card is successfully Synchro Summoned. Draw 1 card from your Deck!"

Soon, after swiftly and cleanly drawing a card from the top of his main deck on his duel disk, Yuufu smiled again, and to everyone's surprise, reached for his extra deck:

"Although this monster card possesses the 'Accelerated Synchro' effect, which allows for 'Synchro' during your opponent's turn, I'm about to unleash something this very turn that will shatter your so-called 'Light of Destruction'..."

"I will instantly boost the power of [Synchro] to its peak—therefore, I will immediately perform the third [Synchro] operation this turn!"

Accompanied by Yufeng's powerful and undeniable voice, he immediately drew a Level 3 Earth-attribute silver-white [Synchro] exclusive monster card. In an instant, two cards on his field—the newly summoned Level 2 [Tuner] [Synchro] monster [Formula Synchron], and the Level 1 [Doppelganger Token]—rose into the air. After entering the Synchro Summoning Channel, Yufeng immediately played a shielded warrior that resembled a samurai:

"1+2=3!"

Synchro Summon - [Royal Defender]!

[Royal Defender]

[Race: Warrior]

[Attribute: Earth]

[Attack power: 1000]
