Purpose of this Deck:
Those who are familiar with Dark Strike Fighter/Catapult Turtle know its nightmare FTK with Magical Scientist. First, you summon Magical Scientist, and then summon Glow-up Bulb/Plaguespreader Zombie. Then use Magical Scientist to summon DSF (Dark Strike Fighter) Then you lose Magical Scientist to keep summoning Fusion Monsters and tribute them with DSF. Then, last, you tribute DSF itself, reducing your opponent's LP to 0.
But sometimes your LP is not enough to summon all those Fusion Monsters. That's why I put cards like Metamorphisis, Thousand-Eye Restrict, and other backups on play.
Card Explanation:
Monsters:
Kinka-Byo: If you know me, I love Kinka (and LV 1 Deck.) Kinka is the monster version of Limit Reverse. Kinka revives Magical Scientist (For OTK), Mystic Piper (For Draw Power), Copycat (Kamakazhi on strong monsters), and Destiny HERO-Disk Commander (For Draw Power).
Magical Scientist: OTK is not possible without this card. Also for XYZ/Thousand-Eye Restrict.
Mystic Piper/Disk Commander: Draw Power. Which is better? Depends on situation (if CoSR is on, Piper is usually better. If I have Creature Swap, Disk Commander is better.)
Copycat: Copycat saves my butt against JD, BLS, and other boss monsters.
Black Luster Soldier-Envoy of the Beginning: Beatstick/Removal Power.
Tragoedia/Gorz/Effect Veiler/Battle Fader/Chaos Emperor Dragon: Protection/Emergency/Burn Dmg.
Sangan/Witch of the Black Forest: My deck's universal searcher.
Spells:
Creature Swap: Since my deck is full of weaklings, creature swaps can really do some serious damage.
CoSR (aka Card of Safe Return)/Graceful Charity/Pot of Greed: Draw Power. Graceful Charity has more purpose by dumping unnecessary monsters to the Graveyard.
Premature Burial/Monster Reborn: Revives my/my opponent's monsters.
Giant Trunade/Heavy Storm/Harpie's Feather Duster: Spell/Trap Destroyers.
Raigeki: A Traditional Deck is not complete without Raigeki.
One for One/Last Will: Another of my monster searcher. Also, one of the OTK setups.
Foolish Burial/Painful Choice: Dumps the useful monsters to the Graveyard, then later revives with Kinka.
Metamorphisis: Aims to stop all the flow of my opponent's Atk by bringing Thousand-Eye Restrict.
Extra Deck:
Dark Strike Fighter: It is another of my crucial monster for OTK. Tribute monsters and keep decreasing opponents' LP.
Lv 6 Fusion Monsters: Dark Strike Fighter's Tributes. Also for XYZ and setup for DSF with Glow-Up Bulb.
Lv 5 Fusion Monsters: Plaguespreader Zombie for DSF.
Thousand-Eye Restrict: Emergency (with Scientist)/Beatstick (If you equip with JD/BLS/Etc.)/Flow Stopper (for Atk/Flip Effects).
Black Rose Dragon: Emergency purpose.
XYZ: Usage for my Scientist.
