Ancient Gear Deck

An Ancient Gear Deck, commonly known as a "Gear Crush Deck", focuses on overwhelming the opponent with powerful Machine-type monsters while preventing them from activating Spell or Trap Cards during the Battle Phase. This strategy relies partly on the "Ancient Gears" and their support cards as well as other cards to give the deck an alternate strategy; cards like "Cyber Dragon" and the Gadgets work very well in this deck in conjunction with a Chimeratech OTK, since all Ancient Gear monsters can be used in the Fusion Summon of "Chimeratech Overdragon" and "Ancient Gear Drill" can search out "Overload Fusion" or "Future Fusion". The Ancient Gears even have their own Fusion Monster, "Ultimate Ancient Gear Golem". Because of the mutual need for fusion cards, and the fact that Ancient Gears need readily access tribute fodder, Chimeratech monsters and Cyber Dragon can be a great asset to this deck.

Strategy
Ancient Gears have gained much strength with the release of "Geartown", which makes summoning high-level gears much easier; "The Trojan Horse" also helps in this respect. Trap-negating cards such as "Jinzo" or "Royal Decree" are also useful to prevent your opponent from activating cards that may hinder the summoning of an Ancient Gear monster. If you run Chimeratech Overdragon, you can even use Jinzo as an extra fusion material monster due to him being a Machine Monster.

Cards like "Cyber Valley", "Morphing Jar", "Cyber Phoenix" and "Hand Destruction" can also be used to draw, gaining major hand advantage and chances to discard for "Overload Fusion" or to perform an OTK with "Dimension Fusion" or "Return from the Different Dimension". Another simpler OTK is to use "Limiter Removal" to double the ATK of all of your face-up monsters. You can also use "Pot of Avarice" to save you from a deck out. In addition, to retrieve cards removed from play, simply use "Burial from a Different Dimension" or "Miracle Dig".

Another variation is to include one or more "The Earth - Hex-Sealed Fusion". Either by using them on the field or from your hand, in conjunction with "Polymerization", "Power Bond" and/or "Limiter Removal", it is possible to quickly achieve an OTK.
