The owner of this deck hasn't added a sideboard, they probably should...

My artifact deck. It's primary win condition is Planar Portal + lots of mana: you can go get Tolarian Academy and then Portal for and play Beacon of Tomorrows over and over again. It also has Metalworker + Staff of Domination and Darksteel Forge + Nevinrryal's Disk. Karn beatdown is also sometimes sufficient. It's mostly one-ofs but I like that style - it keeps it interesting for me - and it's somewhat redeemed by the Planar Portals, which make the deck a toolbox.

Since this is nearly a singleton deck might I just point out that it is very difficult to get the cards you need in the sample hands.

Can't help but think of Pink Floyd =]
You could run some artifact search (Tinker, Fabricate, etc.), 3 more Academies to increase the odds of drawing one, and a lot of cheaper artifacts to make the Academy more worthwhile. These should all allow you to get Planar Portal in place and use it faster, then everything else is butter. You could also throw in Voltaic Key so you could potentially use the Portal twice in a single turn, allowing you to draw your kill cards. Finally, you need some counters just for artifact killers.
Leonidus: Mulliganning is important, but so long as I can access three mana things usually get up and running, and the deck can do well with many different combinations of cards. It makes it unpredictable but I like the variety. Surewhynot: Just another brick in the wall... Zanmor: I'd love to run 4 Academies (and Sol Rings), but my group - wisely, I think - abides by the Vintage restricted list. Adding blue would be wise but this is sort of a concept deck: I wanted to stick with artifacts (though three nonartifacts have slipped in due to how awesome they seem to me).
Understandable, I like this deck it just has to many things going on with it for my simple taste, but if you can play this well thats awsome. I'm sure this deck works like a machine.
If u add Clock of Omens, u gonna be able to do infinite mana and boost Mishra's Factory an infinite way and tap or untap everything u need (p.s. need 2 artifact lands) if u look at this probably u will find good ideas! http://www.mtgvault.com/ViewDeck.aspx?DeckID=142651
