Eh, if you're fighting Yugi/Kaiba clone decks you should be fine with this version, but if we want to fight slightly more powerful opponents... maybe you should switch over to Gadget, the dominant machine-type deck.
-1 Ancient Gear Engineer
-1 Cannon Soldier
-1 Ancient Gear Beast
-1 Ancient Gear Golem
-All VWXYZ cards- five monsters total (they need a dedicated deck to really shine)
-1 Mechanicalchaser
-1 Boot Up Soldier
-1 Ancient Gear Golem
-1 Ancient Gear Gadjiltron Chimera
-1 Ancient Gear Gadgiltron Dragon
-2 Ancient Gear
-1 Ancient Gear Soldier
-1 Ancient Gear Cannon
-2 Heavy Mech Support Platform
And let's replace them with a more standard Gadget monster line-up.
+2 Red Gadget
+2 Green Gadget
+2 Yellow Gadget
+3 Blue Thunder T-45
+2 Kycoo the Ghost Destroyer
+3 Banisher of the Radiance
Admittedly Kycoo isn't a Machine-type, but he fits the deck theme well, as does Banisher.
Now on to the spells- let's captitalize on the strengths of Gadget- each time you summon one, it searches for another.
This means that if you can consistantly destroy your opponent's monster, it doesn't matter if your Gadget gets eaten- you've got another one in your hand, which will search for the next Gadget, and so on. In this way you can generate a lot of CA using one-for-one trades. So, to capitalize on that...
-1 Swords of Revealing Light
-1 Ancient Gear Workshop
-1 Ancient Gear Castle
-1 Frontline Base
-1 Ancient Gear Fist
-1 Ancient Gear Explosive
-1 Ancient Gear Drill
-1 Machine Duplication
Now, let's replace those with a few spells that Gadget absolutely loves.
+3 Creature Swap
+3 Soul Taker
+3 Shrink
All three constitute a one-for-one trade, and Creature Swap lets you trade your wimpy Gadget for whatever big beater your opponent just played. Very nice, eh? Plus, you get to keep the monster you swapped, since control doesn't return at the end of the turn according to official Konami rulings. Long live Konami!
Er, right. On to the trap cards!
-1 Ultimate Offering
-2 Sakuretsu Armor (which is now stomped on courtesy of Dark Armed Dragon decks, dangit, but can be sidedecked and played anywhere you know that you won't be taking on anyone who's serious enough about this card game to spend the cash needed to get the danged card.)
-1 Magic Jammer
-1 Stronghold
-1 Seven Tools of the Bandit
-1 Covering Fire
-1 Rare Metalmorph
-1 Roll Out
+3 Royal Oppression (for all your special-summon stopping needs)
+3 Solemn Judgement (Make them writhe!)
+2 Bottomless Trap Hole (replace with 2 Drastic Drop Off when entering an arena where DAD is a possible opponent)
