Forum:I really need help

I need to power up my deck, it is not bad at all (I suppose) but I feel that I need a theme or something. I use to play with my friends and I can win against some of them, but let's say I'm troubled when I play against Lightsworn or Batteryman decks. I managed to get this cards easily, some of them are gifts. It's pretty difficult to get a very rare card for me but I can buy it via intertet. I'm not buying a $40 card either so please don't tell me to get one of those. Here's the list (please consider that I'm just starting :P)

Monsters

2x Gyroid Mobius the Frost Monarch Sangan Neo Spacian Grand Mole D.D Warrior Lady Spirit Reaper Indomitable Fighter Lei Lei Spear Dragon Treeborn Frog Reflect Bounder Blowback Dragon Great Maju Garzett Copycat Destiny Hero Dasher Charcoal Inpachi

Spells

Heavy Storm Monster Reborn Cold Wave Tribute to the Doomed 2x Back to Square One Giant Trunade Lightning Vortex Scapegoat Mystical Space Typhoon Mage Power Creature Swap 2x Nobleman of Crossout Swords of Revealing Light Shrink

Traps

Scrap Iron Scarecrow Bottomless Trap Hole Draining Shield Trap Hole Magic Jammer Torrential Tribute Threatening Roar Magic Cylinder Seven Tools of the Bandit

Thanks in advance .__.
