Synchro deck help me?

your deck seems to be pretty random. it doesn't mean that it is bad, it just means that you have no real theme to it, besides the synchroing and that there is a lot of lights. good cards like summoner monk could help you synchro level 8's faster. marauding captain can also mean a good one turn synchro. marshmallon can be a good stall ,and then synchro material, you could take out a gellenduo for it, as 3 is not great. and for a synchro deck you might want to run wicked rebirth, this will allow you to maximize the use of your synchro monsters, especially stardust dragon, who's effect would not be negated because it activates in graveyard. the synchronized realms are not essential, and to be honest are a waste to have in your deck, especially if your going to enter a tournament. i would have to say the same thing about ultimate offering and urgent tuning. if you keep ultimate offerings, you can add in 2 of each gadget, red, green and yellow, to make bigger plays and synchro even more in one turn. krebons is also a very good level two tuner and will allow you to go for level 6's and could really help the deck. 3 breakers is too many, make it 2 or less. well, that's pretty much all the advice i have for a deck like this, hope i helped :]
