Although it seems this duel is inevitable, before that...
...Youyu indicated he needed to adjust his card deck.
So Paradox crossed his arms and waited on the side, completely unaware of the seriousness of the situation.
He might even be thinking—
—Hah, adjust all you want.
For him, Youyu is a relic of the distant past. He assumes he knows Youyu's card deck and strategy thoroughly, and believes Youyu knows nothing about him.
Even if he was a Duel King, he's a King of the past after all.
...Could you instantly draw a card against me?
Adjustments complete, Youyu inserted the completed deck into the Duel Disc.
"Hmph, are you ready?" Paradox sneered, "But no matter what, the result won't be any different."
Youyu thought to himself that not long ago, some old immortal with blue hair said the same thing, except he wasn't from the future but from ten thousand years ago. Now his grave...
...Well, he doesn't even have a grave anymore.
"Duel!" x2
[Youyu, LP 4000]
[Paradox, LP 4000]
"My turn, I'll draw." Paradox drew a card, sneering beneath his mask at Youyu.
As someone who traveled from the distant future back to the present, Paradox has absolute confidence in this era.
If you ask why, it's because he knows the history of Duel Monsters, understands the common tactics, strategies, and card deck builds used by renowned duelists of various eras, having a prescient advantage.
In the original, his arrogance led him to take on three Duel Kings from three different eras simultaneously, possibly for this very reason.
He's not unfamiliar with Youyu, the Duel King. He knows that the Duel King uses a Hero Deck, possessing the world's only "Masked Hero" series, adept at transforming and switching forms in battle to avoid attacks and deal with complex scenarios.
Additionally, as a man from the future, Paradox has his own trump card.
That is a powerful deck developed through future technology, far surpassing this era, called the "Malefic" series.
"I'll first activate this card from my hand... Field Magic - Malefic World!"
Youyu's expression turned serious.
As expected, this guy also doesn't shuffle his deck; the key field card is stuck to his hand at the start.
As the Magic Card entered the Duel Disc, a powerful cyclone erupted, centered on the Duel Disc.
The ground transformed visibly into a dark hue; the rooftop below their feet, the surrounding buildings, and the streets below vanished, replaced by a sinister world dyed deep black.
The moment the Field Magic activated, Youyu immediately felt as if the air became heavy, and the pressure from Paradox's robust frame increased significantly.
Disregarding the card's effect and other factors, the power contained in this card... is incredibly strong!
"'Malefic World' is the stage for Malefic Monsters to battle. In this field, I can summon the most powerful monsters from any time and space."
Paradox chuckled confidently, drawing a card from his hand.
"Activating the effect of 'Malefic Rainbow Dragon' from my hand! By sending an 'Ultimate Crystal God - Rainbow Dragon' from the deck to the graveyard, this card can be Special Summoned directly from my hand."
Paradox's futuristic Duel Disc obviously doesn't require manual searching. The Duel Disc intelligently spat out the card he needed from the deck. Paradox took it, and the card deck mounted in the Duel Disc quickly auto-shuffled rapidly with a "swish swish swish" sound.
Paradox showcased the card that popped from the deck, none other than the Legendary Level God Beast, the Ultimate Crystal God - Rainbow Dragon, from "Yu-Gi-Oh! GX."
"Send 'Ultimate Crystal God - Rainbow Dragon' from the deck to the graveyard, appear!" Paradox slapped the card onto the Duel Disc, "Appear, the ultimate gemstone god's sinful form—
—Malefic Rainbow Dragon!"
A hurricane stirred in the Malefic realm, with multicolored rainbow light erupting from the ground. A dragon with a white body, with an aura comparable to a deity, emerged from the rainbow light, circled around the "Malefic World" field, spread its ink-dyed wings, and roared down at Youyu!
[Malefic Rainbow Dragon, Attack Power 4000]
The gale howled in response to the Rainbow Dragon's summons; the airflow whipped like numerous vine whips repeatedly in the confined space.
Dark Magician Girl held onto her nearly-blown-off magic hat, squinting one eye open against the raging wind: "An...a monster with 4000 attack power right off the bat!?"
"Hahahaha!" Paradox laughed heartily, "I said, the Malefic series encompasses the most powerful monsters worldwide and across eras, and they can call out the corresponding 'Malefic' monsters by sending the original monsters to the graveyard from the deck.
You of this era have no means to contend against this power!"
He pulled out two additional cards from his hand.
"Set three cards, turn end."
Paradox crossed his arms; the massive Ultimate Crystal God curled up and slowly descended before him, like an impregnable fortress.
"Come on, try breaking through this malevolent gemstone god's defense, Duel King!" Paradox brimmed with confidence.
"My turn." Unmoved, Youyu acted as if he didn't see the ferocious and mighty gemstone god, "Draw."
If Youyu were truly a native of the animation, he might have been intimidated by Paradox.
The Malefic series, requiring no complex operations, could summon incredibly powerful monsters with attack power up to 4000 almost cost-free. According to the anime effects, the Malefic series monsters even perfectly replicate the effects of the original monsters.
If Uncle Paradox held this deck in the DM era to show off, he might indeed have wreaked havoc.
However, for Youyu, who understood the opponent's details, the flaw of this deck was apparent.
And that is this seemingly high-class Field Magic "Malefic World."
Every Malefic Monster's presence on the field relies on this "Malefic World." Once this Field Magic disappears, all Malefic series monsters would perish on the spot.
From the perspective of transcendent power, the card "Malefic World" actually serves as the key Paradox uses to control Duel Monster spirits.
He traverses different eras, forcibly snatching Duel Monster spirits from their masters; naturally, the spirits wouldn't obediently follow his commands.
Malefic World exists precisely to force these spirits into submission. This card restrains the spirits' power, allowing Paradox to manipulate them into any posture he desires.
Yet, this card's weakness is its lack of resistance; a simple Mystical Space Typhoon can blow it away. Without this field, the spirits Paradox captured would immediately go on strike, manifested in the duel as his field monsters getting annihilated instantly.
...For example, right now.
Youyu calmly drew a card and played it plainly: "Activate Quick-Play Magic - Mystical Space Typhoon, destroy the Field Magic - Malefic World."
Paradox: "!"
