Rate my deck are these good + what should i ditch?

i can tel you now this is a pretty decent deck. the only thing i can see wrong with it would be your giant soldier of stone and seven coloured fish. If you are prepared to spend some money buy a couple more high level monsters like ultimate blue eyes or red eyes black dragon as you only really have blue eyes, black luster soldier and gaia. You can get very good cards very chaeply off ebay nowadays. Good luck. 8/10.
