CHAPTER 10

When I heard the Paradox brothers I groaned. I was annoyed with their rhymeing already. Although they might be a step up from the small fries I've been beating in about 2 turns.
DUEL
"I'll start." I said letting my voice turn a little demonic.
"I play hand destruction now we all toss 2 cards to the graveyard and draw 2 cards from our decks. Next I play Ahrima the wicked warden, and end my turn." I said finishing my turn.
"My turn I draw and play Monster Tamer, and end my turn." Dox said.
"My turn I play Monster reborn to summon Red Eyes B. Dragon." Cipher said, but wait when did he get Red Eyes.
"You motherfucker you went to a tournament without me!" I exclaimed slightly angry.
"Yeah and now we have 2 of the most powerful dark dragon's in existence. Your welcome bitch. Anyway I place 2 cards facedown and end my turn." Cipher said finishing his turn.
"My turn I draw and play Jirai Gumo and play 1 card facedown." Para said.
"Fine! my turn I draw." I looked at the card I drew, and I laughed. Not a laugh like I just heard a funny joke but a evil laugh, because the card I drew would cause them to curl up into a ball and sob. I looked over at Cipher, and could tell he was looking through my mind as he grew an evil smirk.
"Why are you laughing? Have you finally gone insane?" Dox asked.
"Far from it, but you 2 will be soon." I said letting my voice grow more and more demonic as I continued to talk.
"I play Lair of Darkness and sacrifice Jirai Gumo to summon Darkest Diabolos from my graveyard." I said as my dragon rose from the darkness.
"How can you sacrifice our monster to summon yours, and for that matter when did that monster get in the graveyard?" Para said fear evident on his face.
"Lair of Darkness turns your monsters to dark monsters, and lets me tribute your monsters for mine. Diabolos went to my graveyard when I played Hand Destruction." I explained.
"Now Diabolos attack him." I said since Diabolos has 3000 ATK and Monster Tamer has 1800 ATK Dox took 2200 life point damage. They're now at 1200 life points left.
"I set one card facedown and end my turn" Dox said. Cipher drew his card and grinned so I looked through his mind and saw he drew Raigeki Break. He looked over and nodded he played Raigeki Break and destroyed Diabolos, and despite myself I shedded a single tear. Then Cipher played monster reborn again and resummoned Diabolos. He attacked with Diabolos then Red Eyes B. Dragon. The duel was over the Paradox brothers were beaten.
