Machines are my favorite type of monster so I thought I'd build a deck showing off how annoying they can be:

Monsters: 19
3x Machina Gearframe
3x Machina Fortress
3x Ancient Gear Golem
3x Ancient Gear Gadjiltron Dragon
3x Second Booster
3x Meklord Army of Granel
1x Machina Cannon

Spells: 21
3x Mystical Space Typhoon
3x Geartown
3x Soul Taker
3x Terraforming
2x Smashing Ground
1x Seal of Orichalcos
1x Dark Hole
1x Monster Reborn
1x Limiter Removal
1x Night Beam
1x Pot of Avarice
1x Heavy Storm

Extra: 15
3x Big Eye
3x Phantom Beastcraft: Draco SAC
3x Gaia Thunder Charger
2x Gear Gigant X
2x Maestroke
1x Enthusiastic Coach
1x Gagaga Cowboy

This deck uses no traps and usually baits out MST and Storm's with facedown Geartown or any machine equipped with Gearframe. Any feedback would be welcome.
