Forum:In need of deck assistance

I have been dueling my Girlfriend, and I created her deck, and taught her how to play the game. Her deck is the basic Starter Deck for 5Ds with some modifications bringing her total cards to 52. I use 3 different decks, all of 50 cards and seem to be waiting for the right cards to appear, while she kicks my rear end. I would like some help, either making my deck more effective or thinning it out. I just got Stardust Dragon today, so I haven't mathematically figured it into this deck. Any comments or opinions would be greatly appreciated. The deck I am going to list in this post, is my Dino/Warrior/Synchro Deck.

Tuner Monsters 6

Iron Chain Coil Frequency Magician Dark Resonator Comrade Swordsman of Landstar Jutte Fighter Krebons

As you can see there are 3 Level 2 Tuners, and 3 Level 3 Tuners.

Synchro Monsters 3

Stardust Dragon Black Rose Dragon Iron Chain Dragon

Monster Cards 19

Dark Blade Princess of Tsurugi Hyper Hammerhead Black Stego Armor Breaker Ghost Gardna Oyster Meister Sabersaurus Exiled Force The Trojan Horse Iron Chain Blaster Shield Warrior Miracle Jurassic Egg x 2 Ultimate Tyranno Super Conductor Tyranno Black Tyranno Iron Chain Snake x2

Traps 12

Dust Tornado Seismic Shockwave Limit Reverse Hunting Instinct Compulsory Evacuation Device Xing Zhen Hu Sakuretsu Armor x2 Magical Arm Shield Synchro Deflector Negate Attack Volcanic Eruption

Spells 13

Jurassic World Enemy Controller Big Evolution Pill Card Rotator Share the Pain Mirage Tube Soul Exchange Megamorph Lightning Vortex Riryoku Field Barrier Mystical Space Typhoon The Warrior Returning Alive

Any Suggestions, as stated previously are welcome. It seems that I am waiting forever to get the right cards. If you have any ideas in regards to other cards not mentioned here. I have a whole bunch of cards. Chances are good that I have them. Thanks again to anyone that can help me. She likes to use her Synchro Monsters normally Gaia Force of Earth. Scrap Iron Scarecrow x3 and traps. She also uses monsters that don't allow me to activate trap cards during battle phases. And cards that destroy monsters.
