Can u rate or fix my Machina Synchro deck?

The way it is right now i can only give it a 7 out of 10. let fix this up. you got good sychros and u only have 1 tuner. i should replaces the gadgets with other tuners. if u can machine tuners. if u plan on using over dragon replace 1 smashing and 1 fissure for other strong machines.. u can also try to use oilman to draw more cards or use blast sphere to gain field advangtage. also try using royal oppresssion in your main deck and take out 1 dimensonal prison. ur deck doesn;t have much special summoning anyways. i think that is about it
