Forum:Machine deck help please!

I have recently made a new machine type (mainly) deck, and was just wondering if anybody had any tips for improving it?

Monsters (normal): V-Tiger jet, X-head cannon, Overdrive, Whiptail crow (non-machine),

Monsters (effect) : Proto-Cyber dragon (x2), Needle Burrower, W-wing catapault, Y-dragon head, Z-metal tank, Fusilier Dragon The dual mode beast, Machine king, Stamroid (x2), Cyber dragon, Cyber Laser Dragon, KA-2 Des Scissors, Man eater bug (x2) (non-machine), Atomic firely (non-machine), Zolga (non-machine), Big eye (non-machine),

Monsters (fusion) : Chimeratech Overdragon, Cyber End Dragon, XYZ-Dragon Cannon, VX-Tiger catapault, VWXYZ-Dragon Catapault Cannon,

Spell cards : Pot Of Greed (x3), Gravekeepers servant, Exchange, Change of heart, Polymerisation, Shrink, Photon generator unit, Fairy Meteor Crush,

Trap Cards : Raigeki Break, Negate Attack, Fruits Of Kozaky's Studies, DNA surgery, Enchanted Javelin, Kozaky's Self-Destruct Button, Compulsory Evacuation Device, Torrential Tribute, Aqua Chorus

Currently I use DNA sugery to make all monsters Machine-type to increase Machine Kings attack power, And then summon Chimeratech Overdragon by combining Machine King with a Cyber dragon and the rest of the monsters on my side of the field.

Any Other Techniques/strategy's that you can see would be helpful please let me know and also say how i can improve the deck
