Mitsuzawa's premonition was in some ways correct. The Chaos Card Deck doesn't rely heavily on the power of Trap Cards, and in fact, the champion's build back then was equipped with the Trap Lock of the "Royal Palace Notice."
Since the main strength of Chaos was overwhelmingly powerful compared to other Card Decks at the time, when both sides were locked out by Traps, it was naturally advantageous for Chaos.
Yugen: "Activate Continuous Magic 'Nightmare Mirage Tower,' during the opponent's turn preparation phase draw cards until you have four in your hand, but during your own preparation phase, you must randomly discard the same number of cards drawn.
Finally, set one more card, and end the turn."
Mitsuzawa: "My turn, draw a card!"
Within a single turn, the situation reversed dramatically, turning overwhelmingly unfavorable for him. He must think of something this turn.
"Activate Magic Card 'Adversity's Treasure Scroll'! If the opponent has Special Summoned monsters on the field and you have no monsters on your field, draw two cards from the Card Deck!" (Original Card)
The life-saving Treasure Scroll, seeing one of the new cards drawn, Mitsuzawa couldn't help but smile.
It's here! The reversal card!
"Looks like my Card Deck hasn't given up the first place position yet either."
Mitsuzawa raised his head, smiled, and at the same time lifted the Duel Disc in his hand. The graveyard area of the Duel Disc bloomed with bright golden light.
"Number one, do you know what happens to carbon under tremendous pressure?"
Yugen: "Turns into diamond?"
He vaguely remembered Mitsuzawa saying something similar in the original work.
"Oh, you're indeed number one. That's right!" Mitsuzawa said, "In my first turn, the card I discarded to the graveyard with the effect of 'Mathematician' was 'Carbon Dragon'!
The effect of Carbon Dragon. This card can only be activated if there are ten or more cards stacked on top of it in the graveyard!
Banish 'Carbon Dragon' from the game to Special Summon a 'Diamond Dragon' from your hand or graveyard!" (Anime Effect)
It's a unique effect fitting Mitsuzawa's top student persona, but according to the original effect, it's indeed a bit difficult to use. After the physical card of Carbon Dragon was realized, it received significant enhancement; it didn't need to meet this troublesome "ten cards in the graveyard" condition, just banish itself from the graveyard to bring out a level 7 or lower mortal bone Dragon Race from the Card Deck or the graveyard, not limited to "Diamond Dragon," with the added restriction of having to be summoned in defense position.
"Now, over ten cards have already stacked on top of 'Carbon Dragon' in my graveyard, so the effect activates! Transform into the scintillating diamond form and descend—
—level seven, Diamond Dragon, Summon!"
Without seeing the dragon, its dazzling light nearly blinded everyone. A giant dragon, crystal-clear throughout, soared skyward, specks of light scattering like raindrops, the Diamond Dragon with an unparalleled noble aura.
[Diamond Dragon, Attack Power 2100]
The typical card that might not be incredibly powerful but definitely doesn't come cheap at a glance.
Asuka in the stands: "The monster discarded with 'Mathematician's' effect in the first turn... so that Mitsuzawa Earth had plans laid from the start of the duel?"
"But Diamond Dragon's power isn't enough to break the current situation," Marufuji Ryo said, "He must have some other backup move, right?"
True enough, Mitsuzawa confidently smiled: "After Chaos Warrior comes Meteor Black Dragon, legendary monsters one after another... then I too will burn with all my might to duel you!
Activate Equipment Magic 'Gigantification' from my hand, equip it to 'Diamond Dragon'!
When your Life Points are lower than your opponent's, the equipped monster's original Attack Power becomes doubled!"
[Diamond Dragon, Attack Power 2100→Attack Power 4200]
"Attack Power 4200!" The students couldn't help but stir again.
The situation reversed once more!
"Go, Diamond Dragon! Attack 'Chaos Wizard'!"
Yugen's Life Points remain at 1600, Chaos Wizard's Attack Power is only 2300. This strike could directly inflict 1900 massive damage.
Mitsuzawa's desperate counterattack!
Diamond Dragon opened its mouth, and the flowing light within swirled into it, transforming into a spiraling beam of light surging forth!
"Activate Cover Card!" Yugen waved his hand, "Trap Card - Enemy Attack Alert!"
"Kida!" Mitsuzawa shouted, "'Royal Palace Notice' is still on the field, any Traps are useless!"
"I know." Yugen raised his hand, "Therefore, immediately activate the second Cover Card, Speed Attack Magic - Evil Spirit Disperse! Discard a card from your hand, destroy all Continuous Traps on the field.
Destroy 'Royal Palace Notice'!"
Mitsuzawa immediately understood: "I see. Cards activated later resolve effects first, so by the time 'Enemy Attack Alert' resolves, the Continuous Trap 'Royal Palace Notice' is no longer on the field, so the Trap effects can resolve properly..."
"Exactly."
As they spoke, a black storm swept up the backfield Traps, pulverizing the Trap Cards with an overbearing impact.
"Therefore, 'Enemy Attack Alert' effects apply normally. When the opponent's monster declares an attack, Special Summon a monster from the hand. Moreover, the attacking monster must forcefully attack the monster I summoned!" (Original Effect)
Enemy Attack Alert, also from the DM side story "Yu-Gi-Oh! R," a Trap within a Mecha Card Deck.
Mitsuzawa understood: "I see, this way, by summoning a defense monster from the hand, you can evade damage and preserve 'Chaos Wizard'..."
"That's right, but my plan isn't just to evade damage, you know."
Yugen smiled and waved his large hand.
"According to 'Enemy Attack Alert' effect, Special Summon 'Interdimensional Female Warrior' from the hand in defense position, and force her to battle with 'Diamond Dragon'!"
