Might consider {unscythe, killer of kings}

{Master of etherium}?
{Etherium sculptor}

{fabricate}

{master transmuter} also, pairs beautifully with any ETB effect artifacts.

You will likely need more land, too. 30 is pretty light, even if you aren't very worried about colors because of all the artifacts. I would up it to 38 at least, and instead I'd basic lands, try to add a lot of colorless lands that give you a bonus - there's no downside to them when you don't need color! {mystifying maze}, {temple of the false god}, {Darksteel citadel} for example.

Who is the commander here btw? I see {etched monstrosity} so obviously one of the 5 color commanders but didn't see any of them in there.  The scarecrow guy (forget its name) is the only one of them that is an artifact itself.
Edit: nvm I see progenitus now.
