"You don't have to use the card if you don't want to, but I have a feeling you will", Raphael said, confirming what she thought.
It was Yugi's turn now. He lost 500 life points for the five monsters in his graveyard, due to Raphael's magic card. His total life points were now 2200. But he was still confidant that he could win without playing the Seal of Orichalcos. He again ordered Dark Magician Girl the Dragon Knight to attack Guardian Grarl. Raphael activated his face down magic card, Crystal Seal, sealing the dragon in a crystal prison. "There's one card in your hand that will free your dragon. Are you man enough to use it?", he asked. Yugi placed a card face down and said nothing but "I end my turn". Raphael then played Rod of Silence, raising his Backup Gardna's strength by 500 points and allowing him to summon Guardian Kay'est. Next he used Guardian Grarl to attack Yugi's defense monster, Big Shield Gardna. After destroying it, he attacked Yugi's life points directly. Yugi fell to his knees. "This duel is done. You'll lose on your next turn -unless you play the seal", Raphael said. He smiled knowingly. He was sure Yugi growled and drew a card. He lost 600 additonal life points due to Raphael's magic card. That, coupled with the previous attacks, brought his total life points to 600. Deirdra didn't see how he could win now. But Yugi struggled to his feet, saying "If I lose now, two worlds will be destroyed. I won't let that happen!" He played Card of Sanctity, causing them both to draw until they each had six cards in their hands. Raphael and Deirdra could tell from Yugi's expression that he knew that he only had one card in his hand that could help. For the first time since the duel had began, Raphael looked over at Deirdra. "Get back", he commanded. She obeyed. "I play the Seal of Orichalcos!", Yugi shouted moments later, holding the card aloft. The same blinding greenlight that Deirdra had seen in the store room appeared, only this time it was accompanied by a seal that formed around Yugi's feet and grew bigger until it was under Raphael as well. Another smaller seal appeared on Yugi's forehead and a red light flashed in his eyes. He didn't look like the same person. He looked cruel, ruthless, possessed. "Now the Seal of Orichalcos will reveal your true nature, Pharaoh. So, are you good or evil?", Raphael taunted him. Before Yugi could answer, the crystal that encapsulated Dark Magician Girl the Dragon Knight exploded, freeing the monster at last. But to Yugi's astonishment, Timaeus disappeared, leaving Dark Magician Girl alone on the field. "What have you done to my dragon?", Yugi demanded, pointing an accusing finger at Raphael. "It's nothing of my doing. Timaeus and the Orichalcos don't mix", Raphael replied coolly, adding "but your dark side has been set free." Yugi glared at him. "You were a fool to give me this card. Now when you lose, your soul will be lost for all eternity", he said. He then played a magic card called Hand Control. It allowed him to use a card in Raphael's hand if he could guess the name of it. Since he knew Raphael held the card he had received in the exchange, Yugi chose that. The card, Necromancy, let him resurrect four monsters from his graveyard. Big Shield Gardna, Berfomet, Gazelle the King of Mythical Beasts, and Kuribabylon all appeared on the field, and they all gained bonus attack points from the power of the Orichalcos. Yugi sacrificed Berfomet and Gazelle to summon Dark Magician and ordered Kuribabylon to attack Guardian Grarl. Guardian Grarl was destroyed and Raphael's life points went down to 1500. Additionally, his magic card, Purity of the Cemetary, was destroyed since he then had a monster in his graveyard. Yugi next attacked with Dark Magician, but Raphael used a magic card to block the attack.
Out of the corner of her eye, Deirdra saw Joey, Tristan, and Duke appear at the edge of the cliff across the canyon. The three boys shouted at Yugi and waved their arms. Yugi turned to look but didn't answer their calls. Then he turned his attention back to Raphael.
"How does it feel to know that all this time you've been hiding your true self? You derive your power from darkness, and you always have", Raphael said.
Yugi smiled wryly. "Are you jealous because the seal is on my side of the field now and your soul is on the line? Maybe you should have thought twice before giving me the card", he said.
"Your soul is on the line as well. Don't forget that", Raphael answered, drawing two cards. He played Monster Reborn to bring back his Guardian Grarl.
"I've destroyed that monster once, and I'll do it again", Yugi said.
Raphael ignored him. He set a card face down and played the magic card Swords of Revealing Light to stop Yugi from attacking for three turns. Yugi wasn't deterred. He sacrificed Big Shield Gardna to summon Catapult Turtle, which could attack Raphael's life points directly. Raphael activated a trap card, Limit Tribute, to limit Yugi to sacrificing one monster per turn. Since Yugi had already made a scarifice, he had no choice but to end his turn. Raphael next drew and played Nightmare Binding, which took 800 points from Kuribabylon and added them to his life points and prevented Kuribabylon from being sacrificed.
"With the power of the Orichalcos behind me, I can't be stopped. You're finished!", Yugi said, drawing again. He sacrificed Dark Magician and used Catapult Turtle's special effect to inflict damage to Raphael equal to half of Dark Magician's attack points. Raphael was now down to 800 life points. And since Dark Magician was in Yugi's garveyard, Dark Magician Girl's attack points were raised. Yugi once again lauded the dark powers of the Orichalcos and predicted Raphael's demise. From across the canyon, Joey yelled "That doesn't sound like the Yugi I know. C'mon dude, snap out of it!", but Deirdra was the only one to hear him.
Raphael drew two cards, set one face down, and ended his turn. He looked as calm and collected as ever. Yugi drew next, saying "I only have to destroy one card and this duel is over...and I choose my Dark Magician Girl!" Dark Magician Girl reluctantly climbed into the catapult and was launched toward Raphael. Raphael played Shrink, reducing her attack by half and thereby taking only 700 points of damage. He had saved himself for one more turn.
"You'll never escape the Seal of Orichalcos. Your Swords of Revealing Light has expired, so once I sacrifice one more monster, you're fate will be sealed!", Yugi said.
Raphael laughed once more. "I knew the seal would reveal the truth about you. You're wicked, greedy, and full of hate, just like everyone else. The power of the Orichalcos reveals all and, just as I expected, you're evil", he said. "Look at what you've done to your monsters. Once they were pure, but now they're evil shadow creatures."
Yugi looked from monster to monster and saw the angry expressions, red eyes, and glowing seals on each one's forehead. "You deceived me!", he shouted, shaking with rage.
"I didn't. You chose to play the Seal of Orichalcos, even at the cost of losing Timaeus. Your lust for power destroyed a valuable monster", Raphael said. He then drew and played Celestial Sword and Guardian Eatos. Eatos picked up the Celestial Sword, and Raphael activated its special effect, which was to remove monsters from Yugi's garveyard and absorb their collective power. Yugi looked sadly at his monsters as they all flew into the sword. He at last understood they grave error he had made by playing the Seal of Orichalcos. But there was nothing he could do about it now. Guardian Eatos attacked, destroying Yugi's last two monsters and the rest of his life points. The seal shrunk around him, trapping his soul. He fell senseless to the ground as Joey, Tristan, and Duke screamed his name. Raphael knelt by his body and retrieved the Seal of Orichalcos card from his duel disk. Out of nowhere, the helicoptor appeared. Raphael slung Yugi over his shoulders and said "Let's go" to Deirdra. She was too stunned to speak -or move. Raphael took her by the elbow and led her to the ladder that hung from the helicoptor hovering overhead. "Ladies first", he said gruffly.
