Sure, here is the translated text:
Many components of the Gaia deck need to function around the Fusion Monster named "Gaia the Magical Knight of Dragons".
For instance, "Spiral Fusion" can only enhance its power when Fusion Summoning "Gaia the Magical Knight of Dragons"; the Field Magic "Charging Gaia" can only block all opponent effects during the Battle Phase when "Gaia the Magical Knight of Dragons" is on the field; "Curse of Dragon, the Cursed Dragon" must target your own "Gaia the Magical Knight of Dragons" when it enters the graveyard in order to negate opponents' Monster Effects on the field.
However, now the invincible Gaia has been blown away by a Raigeki Break, rendering all the above components ineffective.
"And the card I discarded from my hand when activating 'Raigeki Break' was 'The White Stone of Legend'." Kisara said, "When this card is sent to the graveyard, I can add one 'Blue-Eyes White Dragon' from my deck to my hand."
She drew the card that popped out of her deck and briefly showed it to Youyu. In that instant, Youyu seemed to see the endless void illuminated by a silver-white brilliance, a noble White Dragon spreading its wings and roaring.
But Youyu was not done yet: "Then I will activate the Quick-Play Magic 'The Cost of Desire' from my hand! This card can be activated when the opponent adds a card to their hand outside of a normal draw; Special Summon up to two monsters from my hand."
Youyu revealed the card from his hand he'd already shown earlier this turn.
"Special Summon 'Prison Flame Cursed Dragon' from my hand!"
The long-awaited molten rock broke the earth, and a crimson beam of light surged into the sky. A pair of glowing red wings, akin to fresh blades, sharp and fiery, sliced through the light curtain. The red dragon soared into the sky, breathing scorching light and heat from its mouth.
[Prison Flame Cursed Dragon, Attack 2000]
"The effect of 'Prison Flame Cursed Dragon'," Youyu waved his hand, "Once per turn, you can send this card and other cards used as Fusion Material on the field to the graveyard, no need for a 'Fusion' Magic Card for Fusion Summon!"
Kisara was surprised: "You can still fuse?"
"I send 'Lord Gaia the Fierce Knight' and 'Prison Flame Cursed Dragon' on the field to the graveyard!" Youyu said, "Fusion condition: 'Gaia The Fierce Knight' monster plus a Level 5 Dragon-Type monster! Fusion Summon!
Gaia the Magical Knight of Dragons——!!!"
The dragon's bones seemed to be clad in golden armor, the spiral dual-guns of the Dark Knight stirred up fiery currents!
[Gaia the Magical Knight of Dragons, Attack 2600]
Kisara observed the majestic dragon knight hovering in mid-air, realizing something: "This Fusion Monster, might it also be a dragon knight..."
"That's correct, when 'Gaia the Magical Knight of Dragons' is on the field, it is also treated as 'Gaia the Magical Knight of Dragons' according to the rules."
Youyu smiled.
"In other words, the effect of the Field Magic 'Charging Gaia' is also applicable. When 'Gaia the Magical Knight of Dragons' is on my side of the field, the opponent cannot activate any Magic, Trap, or Monster Effects during the Battle Phase."
A reestablished complete lockdown.
Originally, when 'Maiden with Eyes of Blue' becomes an attack target, she can change to Defense Position on her own, and simultaneously bring out a 'Blue-Eyes White Dragon' from the deck. But in this field she cannot exert her ability, she can only comply and take hits.
If facing a proper opponent, Youyu wouldn't kindly explain the field effect to the opponent before entering the Battle Phase.
However, since the opponent is Kisara, who is not an external enemy, Youyu didn't take advantage of her.
That's the story, but even if he's released this field information to the opponent ahead of time, the lockdown isn't that easily broken.
But the young lady quickly presented her solution: "Flip Cover Card! Trap Card - Interdimensional Matter Transporter!"
"Oh?" Youyu showed a curious expression.
"Select a monster on your field, banish it from play until the end of the turn," Kisara said, "I will banish myself - 'Maiden with Eyes of Blue' from play!
Then at this moment, 'Maiden with Eyes of Blue' effect is activated.
When targeted by a card effect, Special Summon from the deck——
——Blue-Eyes White Dragon!!!"
The dimensional transport device emerged, locking onto the silver-haired blue-eyed maiden on the field. The girl closed her eyes, fingers clenched, her long silver hair fluttering behind her, dazzling brilliance surged, a silver-white dragon emerged from that light cascade, unfolding its silver wings, its blue eyes filled with endless might.
[Blue-Eyes White Dragon, Attack 3000]
"Exiling 'Maiden with Eyes of Blue' from play herself not only avoids the risk of being attacked with an attack power of 0, but also based on this triggers 'Maiden with Eyes of Blue' own ability to Special Summon a Blue-Eyes White Dragon..."
Youyu smiled slightly.
"You are quite capable too."
"Thank you." The White Dragon maiden was quite polite.
But so, the strength reverses once again. Gaia the Magical Knight has an attack power of 2600, not a match for the mighty Blue-Eyes White Dragon.
However, Youyu still has cards to play.
"Magic Card 'Gold Sarcophagus'. Each player draws from their deck until their hand contains six cards!"
Ammo resupply, the key to counter-attack also reemerges.
"Battle!" Youyu waved his hand, "Attack the Blue-Eyes White Dragon with 'Gaia the Magical Knight'!"
The golden dragon flapped its wings, the dragon swooped, the spiral dual-guns carrying shrill whistles, like two streaks of red lightning!
Kisara wondered: "Attacking even if the attack power is insufficient..."
But she had no choice but to counter. The mouth of the Blue-Eyes White Dragon has already opened, the endless white light gathering in its maw, the milky-white turbulent tides racing in all directions!
"Quick-Play Magic 'Gravity Lash'!" Youyu raised his hand to reveal a Magic Card, "Choose one monster on the field, decrease its attack power by its Defense power until the end of the turn!
The one I'm choosing, of course, is 'Blue-Eyes White Dragon'!"
With pressure suddenly increasing on the White Dragon in the midst of gathering energy, it let out a sorrowful cry, much of the energy being accumulated in its mouth escaping.
[Blue-Eyes White Dragon, Attack 3000 → Attack 500]
Strength reversal, Dragon Knight instantly takes the upper hand! The spiral dual-guns effortlessly swept through the greatly weakened burst of white light, piercing right through the White Dragon!
[Kisara, LP 4000 → LP 1900]
"The effect of 'Gaia the Magical Knight of Dragons'." Youyu said, "When he destroys an opponent's monster in battle, his attack power increases by 2600 points!"
[Gaia the Magical Knight of Dragons, Attack 2600 → Attack 5200]
Kisara's face turned pale: "Again, attack power of 5200..."
"End of Battle Phase." Youyu replied, "Activate Magic Card 'A Feather of the Phoenix' from my hand. Discard a card from my hand, return one card from the graveyard to the top of the deck.
The card I want to return is the Magic Card 'Spiral Fusion'."
Spiral Fusion, a fusion card exclusively for Dragon-Type monsters. When Fusion Summoning "Gaia the Magical Knight of Dragons" using this card, that monster's attack power increases by 2600 points, allowed to attack twice in one turn.
A fusion card with destructive killing power.
"Set two cards face-down, turn ends." Youyu said.
"End phase, the effect of 'Interdimensional Matter Transporter' ends too," Kisara said, "my own 'Maiden with Eyes of Blue' will return to the field."
The transport device reappears, the dimensional wormhole opens, and Maiden with Eyes of Blue returns to the field.
[Maiden with Eyes of Blue, Attack 0]
"Now it's your turn." Youyu crossed his arms, smiling, "Good luck."
