You can probably guess what deck this is, based on the name I gave it. This is a Machina deck using the new cards in the Yu-Gi-Oh! Structure Deck, Mechanized Madness. The overall goal of these new cards is to summon your ace monster, Machina Citadel and destroy your own Monsters.
Citadel can revive itself once per turn if any of your EARTH Machines are destroyed, so if you can get it in the Graveyard, you'll likely summon it at least once every duel! In addition, it can destroy a Machine you control and all monsters your opponent controls that don't have more ATK than it. "Deus Ex Machina" truly is an appropriate name for this deck, because Citadel truly is the God In The Machine.
And unlike many other EARTH Machine decks, Machina can do fine going first, in part because of Machina Reformation and Overdrive. It wouldn't hurt to tech Pot of Extravagance, though.
