Machina Gadget

Machina Gadget (マシンガジェ) Decks focus on using the card advantage provided by "Gadget" monsters to summon "Machina Fortress". The main goal is to simplify the game and win due to the constant advantage provided by the "Gadgets".

Machina Gadgets are a popular Deck choice because it is relatively cheap, but able to function well against almost every Deck. There are numerous variations of this Deck. The Machinatown Gadget Deck focuses on Summoning monsters with high ATK. It uses cards such as "Ancient Gear Gadjiltron Dragon" and "Geartown"; the former can be used as fodder for "Machina Fortress", gains effects when a "Gadget" is Tributed to Summon it, and the latter Special Summons "Ancient Gear Gadjiltron Dragon" upon its destruction.

"Machina Gearframe" is used to search "Machina Fortress" and "Machina Cannon". "Machina Cannon" is used as a free "Monster Reborn" for "Machina Fortress". Some decks also use "Machina Peacekeeper" although many regard it as too slow and a potentially dead draw.

The most popular method of winning is to swarm the field and use cards such as "Soul Taker" and other one for one cards to simplify the game to allow the Gadgets to reduce the opponent's Life Points to 0. The Gadgets serve as "floaters", monsters that provide instant +1 Card Advantage to the player. Needless to say, because the Gadgets are Machine types, they have numerous support options available, such as "Cyber Dragon" and "Limiter Removal".

Some Machina Gadget decks utilize "Solidarity" to force the opponent into using removal on the Gadgets and simplifying the game. "Solidarity", however, is sometimes a dead draw, and limits the variety of tech cards and Synchro/Xyz options.

 * Wind-Up Arsenal Zenmaioh (Same as Digvorzhak, King of Heavy Industry, except that this card serves as more of an advanced version of Granmarg the Rock Monarch)

Spell Cards

 * Burden of the Mighty (Use this only if your deck is not only made of Machine-type monsters, including your Extra deck; An alternative to Solidarity)
 * Creature Swap (Give your opponent a weak monster, and take his strong monster)
 * Geartown (in Machinatown variants)
 * Limiter Removal (Can be used for a OTK. Also, monsters used for an Xyz Summon do not get destroyed on that same turn)
 * Machina Armored Unit (Excellent choice due to Gadgets having slightly low stats, and when you not only Special Summon another Gadget, but can add one more Gadget to your hand as well. It works well for any machine-type monster you have, being able to maintain having monsters on the field)

 * Pot of Duality (Speeds up the deck a little bit with no cost to you)

 * Call of the Haunted (Bring back powerful monsters back from the Graveyard with ease)

Weaknesses
Because Machina Gadget decks consist mainly of Machine type monsters, cards like "System Down" and "Cyber Dragon" are used to take advantage. "System Down" wipes out the entire field and Graveyard of Gadgets and "Cyber Dragon" does the same and creates a powerful "Chimeratech Fortress Dragon".
