Before the Frost Monarch could firmly stand, it was destroyed and naturally couldn't launch another attack. So Youyu revealed two cards from his hand.
"With the effect of 'Swap Frog' in my hand, I can discard a Water-Attribute Monster from my hand, except this card, to Special Summon it from my hand.
I discard the Water-Attribute 'Ronintoadin' from my hand to the graveyard, Special Summon 'Swap Frog'."
[Swap Frog, Defense 500]
"I also set one card face-down and end my turn."
"Then it's my turn." The computer continued its mechanical duel, "Continuous Magic 'Blaze Accelerator' activates."
A ball of flame rose from the ground, with a simple cannon setup in the center, the muzzle directly aiming at the frogs on Youyu's field.
Blaze Accelerator, the core of the Volcanic Deck's output, can destroy any opponent's Monster on the field by discarding a Pyro-Type Monster with 500 or less attack from the hand.
And this "Blaze Accelerator" can be upgraded to "Tri-Blaze Accelerator," which can not only destroy Monsters but also deal damage. Moreover, using "Tri-Blaze Accelerator" as a sacrifice can summon the deck's ace, "Volcanic Doomfire," whose attack power is on par with that of a Blue-Eyes White Dragon, terrifyingly powerful...
So Youyu decided to break the incantation directly here.
"Activate the Set Card, the Trap 'Dark Tribute Summon,'" Youyu said, "Adding to my hand a Monster from the grave with 2400 or more attack and 1000 defense, then I can Tribute Summon a Monster with 2400 or more attack and 1000 defense from my hand!"
"Huh?" Mokuba expressed he had never seen this move, "Tribute Summon during the opponent's turn?"
"I return 'Mobius the Frost Monarch' from my graveyard to my hand."
The data flow swirled around his fingertips, transforming into the shape of a card.
"Then I use 'Swap Frog' as a tribute, Tribute Summon 'Mobius the Frost Monarch'!"
A snowstorm rose, and the white giant seemed to burst forth from the Netherworld, its cloak flying like a war flag.
[Mobius the Frost Monarch, Attack 2400]
"Mobius's effect! When summoned, destroy up to two Magic Trap Cards on the field." Youyu waved his hand, "Destroy the 'Blaze Accelerator'!"
The Blaze Accelerator was hit by the Frost Monarch's fist from a distance, shattering into fragments under the sweep of the white whirlwind.
The operation and intent were interrupted, but with its computing power, the computer naturally didn't hesitate. It immediately adjusted its strategy: "The effect of 'Volcanic Slicer,' once per turn, deal 500 damage."
Another fireball missile hit straight on, blowing off half of Youyu's shoulder, but it was soon repaired under the flowing data.
[Youyu, LP 2000 → LP 1500]
"Then I use 'Volcanic Slicer' as a sacrifice, Tribute Summon! Appear, Volcanic Hammerer!"
The Volcanic Slicer vanished wrapped in flames, and a Volcano Monster covered in armor landed heavily. Flames burned between its claws, and the tip of its tail also blazed.
[Volcanic Hammerer, Attack 2400]
Mokuba was a bit nervous: "The attack power is equivalent to the Frost Monarch..."
But it was obvious the Volcanic Deck would not actively attack. The computer continued: "The effect of 'Volcanic Hammerer,' once per turn, inflict damage to the opponent equal to the number of 'Volcanic' Monsters in your graveyard x 200."
Currently, in its graveyard, there are three "Volcanic Scattershots" and one "Volcanic Slicer," four in total.
"800 points of damage!" Mokuba exclaimed.
Four fireballs in quick succession!
[Youyu, LP 1500 → LP 700]
The four holes that were blown open on Youyu's body were continuously restored under the data repair: "Wow, it's quite an engaging play."
The explosive damage capability of Volcanic was fully displayed. In fact, if Youyu hadn't destroyed the opponent's output key "Blaze Accelerator" in time, the output could have been higher, perhaps even resulting in an instant kill.
"End turn." The computer declared.
Indeed, when dealing with a deck like Volcanic that directly saps LP, it needs to be a quick battle.
"Like to sap LP, do you?" Youyu smirked, "Then let's play along."
It's Youyu's turn again.
"My turn, draw." He said, "At the moment of the preparation phase, the effect of 'Treeborn Frog' in the graveyard activated. If there are no Magic Trap Cards on your field, 'Treeborn Frog' can be Special Summoned!"
[Treeborn Frog, Attack 100]
"Then I summon 'Substitoad' in Defense Position!"
[Substitoad, Defense 2000]
Preparation complete.
At this moment, the duel was actually already over.
"The effect of 'Substitoad.'" Youyu said, "Tribute one Monster on your field to Special Summon a 'Frog' Monster from your deck to your field.
I tribute 'Treeborn Frog' to Special Summon the second 'Treeborn Frog' from the deck."
[Treeborn Frog, Attack Power 100]
"The effect of 'Substitoad' doesn't have a once-per-turn limit, so I activate the effect again. I use the second 'Treeborn Frog' as a tribute to special summon the third 'Treeborn Frog'."
[Treeborn Frog, Attack Power 100]
Mokuba started feeling confused.
Using Treeborn Frog as a tribute to special summon Treeborn Frog... what's the point?
"Activate 'Substitoad's' effect again, using 'Treeborn Frog' as a tribute to special summon the second 'Swap Frog' from the deck."
[Swap Frog, Attack Power 1000]
"Use 'Swap Frog' as a tribute to special summon the third 'Swap Frog'."
"Use the third 'Swap Frog' as a tribute to special summon 'Flip Flop Frog' from the deck."
"..."
Since the effect of Substitoad can be activated infinitely, Youyu can keep using frogs as tribute to summon the next frog and then using the next frog as tribute to summon the frog after that...
So Mokuba watched in bewilderment as countless frogs bounced around Youyu's field, like some bizarre frog-themed large-scale performance.
After a long series of mechanical storytelling, Youyu sent a total of three "Treeborn Frog," three "Swap Frog," three "Flip Flop Frog," and three "Poison Draw Frog" to the graveyard, a total of twelve frogs.
Of course, the computer can't have emotions like "surprise" or "confusion," but Mokuba was already stunned.
So then what? Is that it?
Throwing away so many frogs, then what's the use?
Youyu leisurely revealed the "Ultimate Weapon": "Continuous Magic 'Mass Driver,' sacrifice one monster on the field to deal 400 damage to the opponent."
Then another card flew out of the graveyard, revealed towards the opponent.
"The 'Ronintoadin' that went into the graveyard last turn, this card can be special summoned from the graveyard by removing one 'frog' monster in the graveyard from play.
So I remove the 'Treeborn Frog' from play to special summon 'Ronintoadin'."
[Ronintoadin, Attack Power 100]
"The effect of 'Mass Driver,' sacrifice 'Ronintoadin' to deal 400 damage."
Ronintoadin turned into energy and was fed into the cannon, a shot fired and struck the virtual image of the computer right in the chest.
[Computer, LP 4000 →LP 3600]
"The effect of 'Ronintoadin' also doesn't have a once-per-turn limit." Youyu smiled, "So I activate 'Ronintoadin's' effect again, remove the second 'Treeborn Frog' in the graveyard from play and revive it."
[Ronintoadin, Attack Power 100]
"The effect of 'Mass Driver,' sacrifice 'Ronintoadin' to deal 400 damage."
[Computer, LP 3600 →LP 3200]
Even Mokuba realized what was going to happen next.
'Ronintoadin' can be revived as long as a 'frog' monster in the graveyard is banished, and there are a total of twelve 'frog' monsters in the graveyard, doesn't that mean it can revive... twelve times!?
Every time it's revived, use 'Mass Driver' to launch it out, isn't that a total of... 4800 damage?
What the!?
Even though Mokuba had known Youyu for so long, he still couldn't help but be dumbfounded, totally shocked.
Turns out you can play cards like this!?
"..."
[Computer, LP 400]
After a series of relentless bombardments, the computer's life points were already bottomed out, and the outcome was clearly irreversible.
"Again, banish the 'Swap Frog' in the graveyard from the game, special summon 'Ronintoadin.'
[Ronintoadin, Attack Power 100]
"This is the last shot." Youyu smiled and snapped his fingers.
"Activate 'Mass Driver,' sacrifice 'Ronintoadin' to deal 400 damage!"
The last shot, the decisive strike. Ronintoadin transformed into a projectile, accelerated through the long barrel, turning into a golden streak and pierced straight towards the opposing virtual image with overwhelming force.
This time, there was no data recovery; the complete loss of life points simultaneously signified total defeat in this virtual world. The virtual image immediately disintegrated and vanished into a stream of data.
[Computer, LP 400 →LP 0]
