Amnael's Endgame, Part 2

"Professor Banner, you're behind all this?" Jaden asked.
"Of course." He replied, as if it was the most obvious thing in the world.
"Like Chancellor Sheppard said, for the spirit keys to work, they must be won in a duel. Now, before I defeat you, I will tell you the whole story." Banner cleared his throat and began recounting his tale. "Like yourselves, I was once a young duelist with unlimited potential. I scoured the world in search of the rarest and most powerful cards. Finally my travels led me to the ultimate prize… a lost tomb, hidden and buried in an ancient desert. Within… was a duelist's dream, for it held the very first duel cards. Like Pegasus years before, I sought out their powers. Unfortunately… I found more than I was looking for. The tomb was cursed, and science had no answer to the magic that ravage my body. I tried everything, but soon I realized that there was only one thing to be done. I had no choice but to create a new body. Therefore, I created a homunculus, and placed my soul inside of it."
"Um, say what?" Chumley asked.
Banner scoffed at this. "Of course. Heaven forbid any of you pay attention in class. Regardless, despite my efforts, this new body is only temporary. It won't be long before I'm nothing but dust in the wind." Banner gently tapped his cheek, causing a crack to appear in his skin. "As you can see, I don't have much time left."
"Hang on, just wait a second." Jaden spoke up. "You're saying… you're a clone?"
"To live, I need the power of these cards, the three divine Sacred Beasts. And once you lose, the cards are mine." Banner leaned down to set Pharaoh on the ground. "Before you get any ideas about abandoning this duel, don't forget that your friends are still my prisoners. If you walk away, their souls will be mine for all eternity! You have no choice, you must duel me!" Banner gave them a smile that might have been comforting, except for the situation they were in. "Pretend it's your final exam."
"Bring it on!" 
Amnael: 4000
Jaden: 1000
"Now, I believe you hadn't finished your turn yet, Jaden." Amnael reminded him.
"Then I'll place two cards face down and end my turn."
"If you want to save your friends, you must defeat me."
