Forum:What can I do to improve my deck

Well this is a deck my friend help me make its kinda a random deck but its won some games can you just tell me i can improve it thanks in advance.

Random Deck

Extra deck


 * Stardust Dragon
 * Red Dragon Archfiend
 * Iron Chain Dragon
 * Gaia Knight, the Force of Earth
 * X-Saber Urbellum

Side Deck
 * Earthbound Immortal Ccapac Apu
 * Herald of Perfection
 * Different Dimension Ground
 * Crimson Fire
 * Pestilence
 * Genex Controller
 * Needle Soldier

1 Main issue I see with the deck is:

You have too many 'single different' cards, try multiples of the better ones.

if you want, I could try & focus it a bit for you? though of course you'd have to get the recomended cards yourself?
