So this is an idea I've been toying around with since just before the prerelease when all the cards for the set were spoiled. With a bit of tweaking since seeing some of the cards work together this is what I've come up with. The stuff in here seems common sense enough that I'm sure someone somewhere has come up with a similar deck to this. Suggestions are always welcome.
Without further delay, the explanation.
First off we have some obviously good synergy with Ensoul Artifact and most off the artifacts in the deck. Ornithopter is a great choice to ensoul giving you a 5/5 in the air round two.
Tormod's Crypt is a good choice as well due to it's casting cost of on the house. But of course, Darksteel Citadel is likely the best choice as it is a 5/5 beater that can't be hit by things like Cyclonic Rift. I'm not usually a fan of creature lands, but there is something about swinging a 5/5 land that just feels right.
Of course, how would this deck be complete without the Scuttling Doom Engine
+
Shrapnel Blast
combo? 11 damage is devastating at almost any point in the game. Of course, in a pinch any of the artifacts make a great target.
To round this out we have a Generator Servant for some hasty creatures. Again, most creatures benefit from this, but perhaps Illusory Angel is one of the better options here. 4/4 flying haste for a converted cost of three (two of which comes courtesy of the Generator), hard to pass up. Oh course, Goblin Rabblemaster can be sideboarded in to great effect here as well.
On a side(board) note, how about that Pithing Needle like effect on Phyrexian Revoker? I've always loved effects like that, and this guy fits the bill here wonderfully when needed.
