The biggest problem I see is that Pathrazer of Ulamog isn't an artifact, and so is ineligible for most of your ramp stuff. Mycosynth Golem, maybe?

Oh my lord, LavaAndDiamond, I totally linked the wrong card for that. When I stated this:

"I just added two more Semblance Anvil cards to help crank out the really big cards like Blightsteel Colossus and Pathrazer of Ulamog."

I meant to say Darksteel Colossus instead of Pathrazer of Ulamog. But, you are correct; I could replace the ol' Pathrazer. I have had that card in the deck for a while and it has been tough to drop it. It used to play a lot better when I had more of the Everflowing Chalice cards in the deck, but I scaled those back in favor of cards that sped up the play of artifacts.

The Mycosynth Golem is a great choice! I may look into those. Thanks for the catch!

Master Transmuter would be a beast in this deck! Personally I would go up to 4x Steel Overseer and 4x Etherium Sculptor, cutting the Cancel (just too expensive).

Go with Silver Myr over Iron Myr

I didn't even think of the Master Transmuter! Good stuff. I'm gonna see how I can work that in. Thanks, Lee91!

I feel you could benefit from some draw power. Think Twice perhaps?

I like this deck. I've got a similar one in my head that I want to put together. I would replace Cancel with Stoic Rebuttal. +1 from me.

I have not had many issues with draw power for this deck, mostly because everything plays so cheap, but I have had issues where I run out of cards in my hand and keep drawing lands...which is a bummer. I will sideboard some draw spells and test them out. :)

Stoic Rebuttal is a fantastic idea! Thanks for the tip.

If you're looking for draw spells, Thoughtseize is the obvious choice.

...I can't tell if you're joking or if you just linked the wrong card...?

He meant Thoughtcast .

Ah, got it. :) And, yes, that is a legit card for this deck. I will sideboard it until I can try it out. Thanks, folks!
