how can i improve my machine deck?

i would like to create a strong machine deck. for fusion i have cyber end dragon, cyber twin, and gatling dragon. i have one synchro, turbo cannon.(i think i should take it out)

for monsters i have
3x proto cyber dragon
cyber dragon
copycat
turbo rocket
3x cyber phoenix
2x dekoichi the battlefield locomotive
barrel dragon
blowback dragon
JINZO

spells:
limiter removal
power bond
twister
overload fusion
mst
future fusion
heavy storm
polymerization
scapegoat
lightning vortex

taps:
2x sakuretsu armor
spell binding circle
SCrap iron scarecrow
solemn judgemen

i want to create a deck that will let me utilize all of my fusion monsters
should i take out turbo cannon and turbo rocket since they seem useless, along with copycat?

For monsters,i want to add a reflect bounder, king of the swamp, and light hex sealed fusion.

For trap cards i want to add: royal decree, mirror force, waboku, and a imperial iron wall. my friend has a dd deck

and for spells should i add: shrink, swords of revealing light, windstorm of etaqua, and brain control.

would it be good to add these cards.

please advise me on which cards to take out and which to add.
