Forum:Machine Deck Need Help

I also have an extra deck of: Cyber Twin Dragon x2  Cyber End Dragon x1   Chimeratech Overdragon x2   Chimeratech Fortress Dragon x1

I would appreciate suggestions for minor tweaks. Please dont tell me to throw in 2 more machina fortress and a bunch of geartowns and ancient gear things because thats not the point of this deck. Also please dont suggest cards that cost more that $10 a piece because that is more than i am willing to spend on a single card.
