Forum:Machina deck help! Please someone!!!

Well I really need help. I recently bought a "Machina Mayhem" Structure Deck. (click here to see what cards the deck contains http://yugioh.wikia.com/wiki/Structure_Deck:_Machina_Mayhem )

I was wondering what cards should I add to make it better? What to take out? I was thinking of adding a extra copy of "red,yellow. and green gadgets" and a "gadjiton dragon" (however you say it) lol. Should I add that? What else should I do? PLEASE DONT TELL ME TO BUY ANOTHER STRUCTURE DECK!!! Thanks
