Forum:Could someone assist me in making a Dragon Deck

I haven't played in a while & I've collected a fair ammount of cards but for some reason, whenever I try making any Deck, other than my Stall & Crystalbeast Decks, I either get stumped 1/2 way or it ends up as total dissaster & I end up scrapping it. So if anyone can healp me or even supply some tips in making a Dragon, Machiene or Neos Deck would be most appreciated....
