The true final trial in the Land of Trial is the duel with the legendary monster "Black Luster Soldier" from the Dark Yugi's card deck.
If the Duelist wins this duel, they will receive recognition from the "Black Luster Soldier" and obtain its card. Additionally, within this "King's Memory" instance, they can also gain control of this god-level spirit!
Unfortunately, everything in this Memory World is an illusion. The characters and spirits present in this instance, no matter how vivid they seem, are simply NPCs. Hence, the spirit of "Black Luster Soldier" here is also an illusion from the Pharaoh's memory that cannot be brought into the outside real world.
But this does not stop Youyu from acquiring the "Chaos" series card deck!
As long as he passes this trial and obtains the card of "Black Luster Soldier," the "Chaos" series card deck in his System Card Pool will be unlocked instantly!
The name of the Chaos Deck was thunderous among early card enthusiasts, and it was well-known without exception.
This deck was one of the oldest legends in the ancient Yu-Gi-Oh! environment, having claimed the world championship title in various configurations and forms on more than one occasion, dominating the Yu-Gi-Oh! environment for a long period!
Apart from its strength, the deck also gained enormous popularity due to its tie-in with the anime. For example, "Chaos Emperor Dragon - Envoy of the End," a powerhouse card from Kaiba Seto's deck, spent ages sitting in the forbidden list and was long thought by card enthusiasts to remain there until K Corp's collapse.
Moreover, the ace of Muto Yugi, "Black Luster Soldier," and "Black Luster Soldier - Envoy of the Beginning" from "Yu-Gi-Oh! GX," were incredibly powerful monsters that severely disrupted balance in their era, known in the GX Animation as "the strongest warrior in the Duel Monster Realm," exclusive to the first Duel King Muto Yugi's deck.
And at this moment, Youyu had already stepped into the center of the field, standing before this legendary warrior.
Champion Card Deck!
Other decks can be set aside for now, but the "Chaos" series is a must-have for him!
Youyu activated his Duel Disc.
"A warrior from beyond this space-time, huh."
As expected, the Black Luster Soldier was different from other NPCs, seemingly recognizing at a glance that Youyu was an intruder in this world.
But he didn't mind: "Perfect. It doesn't matter who you are, I haven't encountered a worthy opponent in a long time."
With that, a golden flash appeared on his arm's ancient duel disc, and five massive stone slabs fell with a deafening roar and swirling dust.
"Since you have passed the trial, your strength has already been proven." He said indifferently, "Don't disappoint me."

[Youyu, LP 4000]
"I'll go first."
Black Luster Soldier raised his arm, and the heavy golden stone slab fell from the sky with a roar, landing with an explosion of yellow dust.
He glanced around the surroundings and then calmly said: "First, let me prepare the most suitable field for this battle ceremony.
Descend—Gateway to Chaos!"
The turned stone slab was evidently a Field Magic card. The earth-colored slab cracked open, releasing a mighty and surging energy from the fractured stones.
Like blue waves swiftly sweeping across the field, the forces of light and dark collided and crossed, gradually breeding a concept called "Chaos," whose contained power could both create worlds and bring all things to an end!
Field Magic—Gateway to Chaos, when activated, allows the player to add a "Black Luster Soldier" Ritual Monster or a "Charging Gaia the Fierce Knight" monster from the deck to the hand.
Another stone slab descended from the sky, and after flipping over, it briefly displayed itself to Youyu. Although the engravings on the slab were somewhat abstract, Youyu still recognized it as depicting the Black Luster Soldier himself.
"Next is the time for the Sacred Ceremony!"
The Black Luster Soldier waved his hand again, and another stone slab flipped over in front of him.
Ritual Magic—Black Luster Ritual! Use monsters whose combined levels exceed eight from the hand or field as Tribute to Ritual Summon "Black Luster Soldier" from the hand.
A black altar emerged, flanked by flaming braziers, with a delicate emblem in the center. Silver-white longswords stood crossed, the flickering flame clearly reflected on the sword blades.
Two monsters appeared simultaneously as sacrifices. On the left was the level seven "Charging Gaia the Fierce Knight," and on the right was the level four "Dark Knight of Gaia."
"One soul guides the light, one soul guides the darkness, and the gate of chaos will open here!"
The Black Luster Soldier waved his armored arm as if drawing a divine sword that cleaves all things.
"I summon myself here, in the ceremony of this battle—
—Black Luster Soldier, descend!"
A vortex of chaos erupted from the altar, the golden light in mid-air coalescing into a human form. The swordsman in blue armor descended from the sky, wielding a blue shield and a sharp longsword, his boots landing like a flag planted into the ground.
He lightly waved his longsword, and the gust of sword qi seemed to cut off breath. Though his stance was restrained, his blue figure harbored a presence that even Dragon-Type kings dare not underestimate.

"Firstly, when 'Charging Gaia the Fierce Knight' is used as a sacrifice, I can call the stone slab of 'Black Luster Soldier' to my hand.
Next, when the 'Dark Knight of Gaia' is used as a ritual sacrifice, the hidden ability of 'Black Luster Soldier' will be unsealed."
Black Luster Soldier raised his hand.
"Blade of Time and Space!"
Black Luster Soldier swung his sword, and the silver-white blade cut a silver trajectory in the air! That sword qi seemed to transcend time and space, shooting across the air and directly hitting one of the five cards in Youyu's hand, making it vanish into thin air from Youyu's hand.
Youyu frowned slightly without saying a word.
Dark Knight of Gaia, a level four ritual tribute exclusive to Black Luster Soldier. When this card is used as a tribute for the ritual summon of "Black Luster Soldier," the summoned "Black Luster Soldier" gains two effects:
Once per turn, you can banish one monster on the opponent's field from the game; or once per turn, banish one random card from the opponent's hand from the game until the end of the opponent's next turn.
Evidently, the opponent had just used the latter effect, forcibly reducing the number of usable hand card resources for the opponent.
Either of the effects mentioned above is an unreasonably strong offensive means.
And this is merely the tip of the iceberg of "Black Luster Soldier's" sealed power. The true strength hidden by this legendary warrior far exceeds this.
"The moment the two souls were sacrificed, the function of 'Gateway to Chaos' was also activated," Black Luster Soldier said indifferently, "In this battle, every soul that goes to the graveyard will add a Spell Counter to 'Gateway to Chaos'."
For every card sent to the graveyard, whether from hand or field, Gateway to Chaos will increase a Spell Counter. Since two tributes were just sent to the graveyard, the Spell Counter of "Gateway to Chaos" is now two.
"My actions end here," said the Black Luster Soldier, "Come, warrior from beyond this space-time, prove your strength to me."
