Help building a cyber machine deck(yugioh card)?

The people above is wrong,you can't add more than 2 cyber dragon(advanced and traditional format).If you want another cyber dragon you can add cyber dragon zwei(the name on the field can become cyber dragon by revealing 1 spell card to opponent).You can add another support light monster like honest,shining angel,light hex sealed fusion,etc.1 copy of Future fusion and 2 copies of power bond can be useful in this deck.You can add(2 of each) chimeratech,cyber twin,cyber end,cyberdark dragon in your extra deck.
