Forum:Fine Tuning my V-Z or XYZ Deck, need some input please

This is a pure Machine type deck minus one monster at the moment. I would like to know if it is at all possible for me to lower the card count down to 40 with out losing to much power. If anyone has any suggestions to making the deck better than what it is, I would love to read them. Thanks for any and all help.
