Here is the English translation of the provided text:
This trap only requires half of your Life Points to negate the opponent's monster summoning or the activation of a magic trap. In actual combat, stepping into just this one 'Forbidden' could largely dictate the direction of the duel, especially in the early environment.
And this kind of power that can 'negate all magic, traps, and monster effects' is embodied in the Light and Darkness Dragon, which can block four times!
A duelist, after all, starts with only six cards, so a single Light and Darkness Dragon can negate the opponent's first four actions!
This powerful ability once made it prevalent in the physical card environment back then, enough for card enthusiasts to often prepare some specific counter cards for the 'Light and Darkness Dragon' in their side decks, showcasing its strength at that time.
Of course, its effect is not perfect. Despite its strength, the Light and Darkness Dragon also has flaws.
For instance, its effect mandates activation—whenever there's a magic, trap, or monster effect triggered, it must deduct 500 attack and defense points to negate that effect, and it doesn't differentiate between friend or foe.
Additionally, concerning magic traps, it can only negate the 'activation of the card' but cannot negate the effect activation of already existing cards in the field, like Continuous Magic and Continuous Trap cards.
Nevertheless, this doesn't affect it being a truly powerful monster, definitely a trump card in any card deck.
Right now, Judai indeed does not possess a card that can defeat it.
'Really, a tricky opponent has emerged.' Yubel sneered, paused, 'However... it's not that there isn't a way to defeat it.'
'Eh?' Judai was taken aback. Associating the pros and cons of the Light and Darkness Dragon's ability, he suddenly recalled the card that Youyu-sensei had handed him before the duel.
That's it!
If it's the power of that card...
Judai was startled for a brief moment.
Could it be that Youyu-sensei... had anticipated that Manjome would summon the 'Light and Darkness Dragon', hence handed me that card?
Judai's mind quickly became active.
'Already noticed?' Yubel chuckled softly.
'Yeah.' Judai chuckled, 'As long as during the next draw, I can get that card, right?'
Yubel smiled, 'With you, that's certainly no problem.'
'Who knows?' Judai rubbed his nose, full of anticipation, 'Well, it's my turn now, Manjome!'
'Yes, sir!' Manjome emphasized, but at the same time felt a bit uneasy seeing Judai so full of motivation.
This guy... does he really have some reversal move?
'Let's go then! My turn!'
Judai positioned his fingers over the top card of the deck, his actions momentarily paused, as though brewing something.
'Draw!'
The card was drawn.
A single draw, as if the world opened up, accompanied by a new world being created.
A possibility took root in the present, birthing a brand new future.
'Here it comes!' Judai's eyes lit up.
'I told you you'd certainly succeed.'
Yubel seemed unsurprised, but his gaze at Judai became even more distant.
Indeed, my Judai!
Full of overflowing love.
'I'm going for it, Manjome!'
'Yes, sir!' Manjome continued emphasizing.
'I'll also utilize your field magic effect!' Judai shouted, 'Pay 1000 Life Points, Tribute Summon a monster without sacrifice!'
[Judai, LP 1700 → LP 700]
'What I will summon is this card! A dragon that shatters everything into atoms—
—Gandora the Dragon of Destruction!!!'
'What?!' x10086
The entire field was shocked!
President Haima's expression instantly froze, pupils contracted, his eyes filled with astonishment.
Gandora the Dragon of Destruction… isn't that Yugi's ace monster?!
Could it be, the card he gave to this kid is not just a Kuriboh?!
That cunning Yugi!
Haima gritted his teeth in anger.
He felt targeted by these two Duel Kings!
Youyu noticed the president's reaction but merely coughed slightly, pretending not to see.
The truth is, this shouldn't be blamed on Yugi. Gandora is indeed Yugi's ace, yet the card in Judai's hand wasn't actually given by Yugi—but it was him...
The dragon of darkness tore through the earth, its sturdy body like forged from black iron! Its entire structure seemed to have opened numerous eyes, each radiating out scorching cutting light beams!
'Gandora the Dragon of Destruction's effect!' Judai declared, 'Pay half of your Life Points, destroy all cards on the field except itself, and banish them from the game!'
[Judai, LP 700 → LP 350]
Lasers shot out in all directions, as though transforming all they touched into atoms!
Giga Rays!
'Then, Light and Darkness Dragon's effect!' Manjome shouted, 'Negate Gandora's power!'
The dragon of light and darkness roared! Black and white lightning struck the dragon of destruction's body, binding the world-annihilating power back into its core!
[Light and Darkness Dragon, Attack 2300 / Defense 1900 → Attack 1800 / Defense 1400]
Judai chuckled, 'Then Gandora the Dragon of Destruction's effect activates again. Pay half of your Life Points, destroy and banish all cards on the field!'
Manjome then realized with astonishment: 'What? Gandora's ability… doesn't have a once-per-turn limit?!'
[Judai, LP 350 → LP 175]
The dragon's power activated again, Manjome had no choice but to grit his teeth: 'Light and Darkness Dragon, negate it again!'
[Light and Darkness Dragon, Attack 1800 / Defense 1400 → Attack 1300 / Defense 900]
'Then activate Gandora the Dragon of Destruction's ability once more!' Judai declared, 'Giga Rays!'
Manjome sighed: 'Light and Darkness Dragon, negate that effect!'
[Light and Darkness Dragon, Attack 1300 / Defense 900 → Attack 800 / Defense 400]
With just 400 defense points remaining, Light and Darkness Dragon's ability could no longer be sustained.
It's over.
'Gandora the Dragon of Destruction, effect activated!' Judai proclaimed, 'Pay half of your Life Points, destroy all cards except itself and banish them!'
[Judai, LP 175 → LP 88]
This time, there were finally no obstacles, the destructive light scoured everything. Ancient tombs crumbled, fire pits fell to the ground, buildings collapsed in large sections, rubble cracked loudly and shattered into powder on the floor.
Light and Darkness Dragon screeched helplessly, similarly unable to withstand the divine power of 'Giga Rays'. It was directly hit by a beam of death light, its body disintegrated into countless particles, dissipating like glowing dust.
'Gandora the Dragon of Destruction's follow-up effect raises its attack power by the number of cards destroyed by this effect x300!'
[Gandora the Dragon of Destruction, Attack 0 → Attack 900]
900 attack power, far from being overly high, but more than enough to conclude this duel.
The dragon of destruction opened its maw, brewing the final strike. The burst of red stream engulfed Manjome head-on.
[Manjome, LP 400 → LP 0]
