UB - The schemer (Frontier)

This is my frontier, black and blue, artifact deck.

Focused mainly in artifacts, as it should be of course, specially on thopters, and the ability to turn them into powerfull flying monsters with cards like "Ensoul artifact", "Chief of the foundry" and "Stoneforge Masterwork" wich is the most similar artifact in frontier to "Cranial plating" working with creature types instead of card types, so your thopters will buff for each other thopter in the battlefield.
(Note that if you have a Mirrodin "Ornithopter" it wont show a creature type, but it does have, or at least, now it does)

Other useful uses for different cards are these:
You can use "Ensoul artifact" on a "Darksteel Citadel", to provide you with a 5/5 indestuctible artifact creature wich can kill or just block dangerous creatures, and provide mana to buff your "Hangarback walker" before your turn.

Also, you can animate your "Smuggler's copter", to have a 5/5 flying creature wich lets you draw and discard if you are in need of a better hand.

You can use "Mechanized production" in various ways, and each one of them is very useful in this deck!
For example, you can enchant one "Darksteel citadel", each turn you will get an addicional INDESTRUCTIBLE mana, in addition to the land turn
In addition, your opponent will be forced to defeat you in a number of turns determined by how many Citadels you already had if he doesnt have removal for your enchantment.

You can also enchant a Thopter if you have enough of them to win on your next turn, specially if you can just create more with "Efficient construction"
This also will buff your thopters equipped with "Stoneforge Masterwork"

You can enchant Chiefs or Inspectors, Chiefs will buff all your other artifacts for each one you have, so each turn, each of your thopters, each other Chief and your animated artifacts, like "Darksteel Citadel" or "Smuggler's copter", will get an additional +1/+1

You can also play the "Gearseeker serpent" very easily for just 2 manas, putting on the battlefield a 5/6 wich can be made unblockable, you can even have one on your opening hand and you shouldnt have problems to cast it in a few turns.

"Battle at the bridge" is there to act as both a removal, and some lifegaining if you are in need of it, you can pay just enough to kill a creature and heal, OR if you have "Paradox Engine" on the battlefield, you can just tap all your artifacts to heal a even greater amount of health.
(Note that animated lands wont untap as they are still lands)

And the final touch, "Tezzeret the Schemer", the new Tezzeret added on Aether Revolt might not be as powerfull as Tezzeret the seeker, or Tezzeret, Agent of Bolas, but damn, he is a Tezzeret, and his abilities prove it.
Not only you can cast it for 4, and enters with 5 Loyalty counters, he can also give you one mana of any color in the form of an artifact, wich you can also tap to cast your Sorceries with improvise without even have to sacrifice them.

You can also use his second ability as a removal, or a buff if a Thopter is powerfull enough to endure the +X/-X effect.

And the best part about it, just two turns after casting him, you can get his emblem, wich will turn one of your artifact in a 5/5 permanently, you can animate more lands, make thopters stronger!

You shouldn't get to the point where you need the emblem, as you probably would have won already just by contantly attacking with your thopters and properly use your enchantments, but as you can never know, the moment you play the emblem it should mean a total win for you.
