Just like the original Three Egyptian God, each Phantasm is also unique. They do not allow their cards to be faked, copied, or reprinted; any such behavior would incur the wrath of the divine phantoms, resulting in the destruction of the Duelist themselves.
Of course, there are exceptions.
For instance, there is a certain dragon-centric character from the GX Animation—a Card Designer from the International Fantasy Society. He successfully copied the Supreme God among the Egyptian God, "The Winged Dragon of Ra," and developed the Field Magic "Mound of the Bound Creator" capable of restraining even the power of the Egyptian God.
The result in actual combat was that he successfully summoned "The Winged Dragon of Ra." Just as the Egyptian God was about to deliver divine punishment, it was immediately restrained by the Mound of the Bound Creator Field Magic.
Through such means, even an ordinary person without the Pharaoh's bloodline or recognition from the gods could temporarily gain the authority to command a god.
So, as long as you have a power that transcends or can even bind a god-level spirit, using replica cards is not impossible.
Alternatively, if under special circumstances, you receive recognition from these divine phantoms themselves, you can naturally use replica cards to summon their true presence.
A clear example of this situation is Kagemaru.
"The incalculable wealth and resources invested, the years of constant discovery, and just when I had nearly exhausted all the wealth I had accumulated my entire life, causing the Heaven and Earth Imaging Society I founded to teeter on the brink of collapse, and when I was in despair and almost about to give up, they appeared at last."
Kagemaru smugly flaunted the three cards in his hand, which housed extraordinary power.
Uria, Lord of Searing Flames; Hamon, Lord of Striking Thunder; Raviel, Lord of Phantasms.
The Three Phantasm.
"I found the ancient slabs from the ancient era that sealed the Phantasms themselves." Kagemaru smirked, "I obtained their permission, and using the industrial power of the Heaven and Earth Imaging Society, I succeeded in creating these three cards—with almost no resistance encountered along the way.
You see, I have to thank you for that, Duel King Youyu. They resent you for having defeated and sealed them, causing them humiliation.
The sole condition they gave me for their recognition and becoming their Master was..."
"Defeat me." Youyu understood.
"Exactly." Kagemaru sneered, "Daitokuji's research had a fatal flaw, the bodies created by Alchemy are destined for destruction. But the power of the Phantasms can help me patch up that flaw—
—as long as the Three Phantasm are present, I can endlessly replenish my Life Energy, becoming truly immortal and the supreme ruler, forever reigning over this world!"
His voice was thunderous, echoing like rolling thunder in the enclosed room. Red, blue, and gold energy erupted magnificently from behind him, taking an abstract form of the Phantasm in mid-air, their overwhelming aura enveloping Youyu.
At this point, Youyu wasn't sure if the consciousness standing before him was more Kagemaru's... or the Three Phantasm's.
Everyone was caught up in the struggle, the mastermind behind the scenes might just be hiding an even bigger master plan—the real power behind the endless battles over the Three Phantasm might indeed be the Three Phantasm themselves.
Whether it's Tragoedia or Kagemaru, they were all just pawns in their revenge.
Perhaps Kagemaru thought he was the one who had the last laugh, but in reality, his consciousness had long been controlled by the Phantasm. Now, he was merely a tool used by the Three Phantasm to exact revenge on Youyu.
It seems there's nothing more to say.
Youyu activated the Duel Disc and inserted the Card Deck. The indicators on the Duel Disc lit up, LED-like pale blue light illuminating every groove of the mechanical device.
"I've dealt with you three before, I can do it again." Youyu said calmly.
Kagemaru smirked, "This time is completely different, I assure you. After today, there will be no more hiding, no more schemes.
After today, I will conquer all with absolute strength!"
"Duel!" x2
[Kagemaru, LP 4000]

"I'll go first, draw."
Kagemaru drew a card from his hand.
"First, I activate the Continuous Magic 'Thunder of Fallen.' Next, I set three Magic Cards on the field!"
Three Set Cards emerged on the field, and he deliberately emphasized that they were Magic Cards.
Youyu's eyes flickered slightly.
Is it happening so soon?
"Send the three Set Magic Cards on the field to the graveyard! Thunder of Fallen descends from the heavens, delivering heavenly punishment upon the mortal world—
—Summon Hamon, Lord of Striking Thunder!!!"
Outside the building, the wind swirled, and the tides rose and fell against the sea. From within the black clouds, a bolt of lightning brewed, transformed into a substantive force under the influence of dark power, piercing through the rooftop of the building they were in with a shrill scream!
The ceiling, reinforced with thick steel plates, was blasted to pieces as the entire building seemed to scream as if collapsing.
A golden demon descended from beyond the heavens. It was a terrifying figure difficult to describe with words, a perfect blend of alien beauty and demonic ferocity in its crude lines.
The pure golden body and appearance were unmistakably reminiscent of "The Winged Dragon of Ra" among the Egyptian God, except this demon's body was more like a skeleton structure, each golden bone entwined by tiny serpents of electricity, as though stepping out from the gates of Hell.
That was indeed one of the Three Phantasm, Hamon, Lord of Striking Thunder, fought over fiercely by various forces!
Hamon, also known as Amon, stems from the seventh Demon God of Solomon's 72 Demon Gods.
In the animation, the Phantasm was exaggerated to be equivalent to the Egyptian God, yet failed to show a corresponding power. But now, Youyu knew that the slabs sealing fragments of the Phantasm power had all fallen into Kagemaru's hands, and he had to assume Kagemaru had successfully made those slabs into cards.
This means that the Three Phantasm Kagemaru now holds could be in their strongest form ever seen, even beyond the animation!
"Field Magic 'Fallen Paradise' activates."
With the activation of the Field Magic, the dual arena was transformed into a barren, desolate dark wasteland.
"'Fallen Paradise' allows me to draw two cards from my deck once per turn if I control a Three Phantasm on the field." Kagemaru said indifferently, "Since I currently have 'Hamon, Lord of Striking Thunder' on the field, 'Fallen Paradise's effect activates. I draw two cards from my deck."
After glancing at the drawn cards, he added them to his hand, then gave a mysterious smile.
"The Continuous Magic 'Thunder of Fallen' is 'Hamon, Lord of Striking Thunder's exclusive magic card, releasing Hamon's true hidden power!"
Another thunderbolt descended, as if a layer of electrical armor wrapped around Hamon's golden body, crackling as it ran along its golden bones.
"Turn ends." Kagemaru stated, "Come, Duel King! If you can defeat the strongest demon in history, give it a try!"
