Rate/fix my yugioh deck?

i think this deck could do really well in a tournament, but instead of negate attack, i would suggest malefic stardust dragon. He is really good if you have a Field spell out. As long as hes in your hand, all you have to do is discard one stardust dragon from your deck or hand to play him, although there has to be a Field spell activated. Good news is that the Field spell cant be destroyed as long as hes on the Field:)
