I know the others were a little rushed, but I'll try to take some time with this one.

Andrew flew towards the town of equality. "I hope Diamond will be okay." he muttered.

"Don't worry, she's got Silver." Flame replied. Andrew nodded and continued his flight.

...

"Thanks for coming with me, Sil." Diamond said as they walked towards the lake.

"No problem, I would never leave my best pal hanging." Silver replied. "Oh, did I tell you Button finally proposed?"

"Seriously? That's awesome! I hope he and Sweetie Bell will be happy." Diamond laughed and grew serious. "We're here."

"So slow, how often has that happened my little brat?" Filthy asked, standing up. "Let's duel."

"Gold Digger, engaged."

Filthy Rich:8000

Diamond Tiara:8000

"Ladies first. I summon Gem Armadillo(ATK:1700),"

"I thought you gave that to Andrew." Silver called from the sidelines.

"I have spares. Now that I summoned him I can add one gem-knight from my deck to my hoof. I play Polymerization. I fuse Gem-knight Amber and Gem Armadillo to form Gem-Knight Zirconia(ATK:2900). I end my turn with two cards facedown."

"My move. I summon Volcanic Slicer(ATK:1800). I play his ability. You take 500 points of damage." Slicer bypassed the knight and stood in front of the mare. "Go Volcano flare!" it let loose a jet of flames.

Diamond:8000-7500

"I play two cards facedown and end my turn."

"My move. I play Gem-Knight Fusion. Gem Knight Sapphire and Garnet combine into Gem-Knight Aquamarine(ATK:1400)."

"Such a weak monster, perfect for such a pathetic little filly." Filthy taunted.

"I activate the Gravity ax-Grarl and equip it to Aquamarine(ATK:1400-1900). Then I play my facedown Mystical Space Typhoon to destroy your facedown on the right." the card exploded. "Aquamarine attack!"

Filthy Rich:8000-7900

"Aquamarine switches to defense mode(DEF:2600), and I'm not done yet. Zirconia, attack him directly." Filthy didn't flinch.

Filthy:7900-5000

"I end my turn."

"How amusing. My draw." Filthy grinned. "I play the field spell Volcano. Now all fire monsters gain 200 attack points. I summon Volcanic Rocket(ATK:1900) and now I can add my Blaze accelerator from my deck to my hoof. I think I'll play it now. And now that it's activated, I can send one of my weak Pyros, like my Volcanic Rat, and destroy your Zirconia." the blaze hit Zirconia and shattered him.

"Not good, but you can't attack on the turn you use your accelerator."

"Right you are, but somepony must have told you that a few minutes ago or you wouldn't have the brain to remember. I end my turn."

"I draw." Diamond looked at her card. Armor Ninjitsu Art of Freezing, that takes me back.

...

"Aquamarine attack!" young Diamond called. Silver smiled from the sidelines as the bully's life points hit 0. "I'll take back Silver's card now." Diamond took the ninja and walked over to her former friend. "Here you go."

"Thanks," Silver slipped the card back into her deck, "Hey, I want you to have this, and I want to say I hope we can be friends again." the filly handed over a card.

"Armor Ninjitsu Art of Freezing." Diamond read.

"To show that even when others give you the cold shoulder, you'll always be there fro your friends."

"Yeah, let's go to our spot, old friend." the fillies walked off.

...

Silver gave me this as a token of friendship, and I have every intention to put it to use. "I play one card facedown and summon this in defense mode. Then I'll call it a turn."

"My move, I draw. I sacrifice my rocket to summon Volcanic Hammerhead(ATK:2400-2600). Next I'll activate his ability. You take 200 points of damage for every Volcanic in my graveyard. I count two, which means you take 400 points of damage." Hammerhead exhaled, causing Diamond to flinch.

Diamond Tiara:7500-7100

"You've had enough. I end my turn."

"My move, I draw." Diamond smiled. "I play the field spell Gem World, which means your Hammerhead loses his boost(ATK:2600-2400). Now all my Gem-Knights gain a 1000 point boost. Pretty neat, huh?" Filthy snarled. "Aquamarine switches to attack mode(ATK:1900-2900), and now attack with Gravity Slash!"

Filthy Rich:5000-4500

"I end my turn."

"My move. I activate Monster Reborn to resummon my Rocket, then I'll sacrifice them both to summon Earthbound Immortal Huacachina Kon(ATK:2700). Attack her directly. Heron Striker." the giant bird swooped in and attempted to strike.

"Not so fast, I have a trap. Freeze that bird out, Armor Ninjitsu Art of Freezing. Not only does it negate your attack it freezes your monsters in their battle positions." Kon returned to it's master's side covered in frost.

"I end my turn."

"My move. I summon Gem-Knight Alexandrite(ATK:1800-2800), then I activate Fissure to destroy your monster."

"That destroys all your spell and trap cards." Just before Kon was destroyed, it beat it's wings and all the cards behind the monsters.

"No! My Armor Ninjitsu!" Diamond shrieked, "Okay, I'm still in this. Aquamarine, Alexandrite, attack! His stain on my life ends now!" both monsters went in for the kill.

Filthy Rich:4500-0

"All hail." Filthy vaporised. "Come on Silver, Dad'll be worried if I don't get home before Dinky and him both." the mares walked back the way they had come.

...

Derpy landed in Cloudsdale. "Osiris!" she called out. "Osiris answer me. Show your face!" the cloaked pony stepped into the moon's light. "Lose the cloak. It doesn't fit you well little brother."

Little Brother?! Well this'll be interesting.
