would Metalwork Colossus be good in a deck like this?

I feel it gets outclassed because of its lack of trample, and indestructible that Darksteel Colossus has or the infect that comes from Blightsteel Colossus. Might have use in a Daretti, Scrap Savant deck though.

Indeed, its better to hit Blightsteel Colossus with Muzzio, but Metalwork Colossus is much easier to cast from your hand, and its an easy way to get an cmc 11 artifact onto the board.

Nice deck! I love artifact decks. Have you considered putting in Karn, Silver Golem? He provides more value out of your non-creature artifacts. He's also really fun with Mycosynth Lattice because you can just start popping lands.

With regard to the Metalwork Colossus I will be testing it as soon as i get my hands on a copy, and i'd suggest you at least give it a shot. Here is why. After about CMC 7, the availability of even halfway decent artifacts is severely limited. There's a few on 8, fewer on 9, and by 10 they get REALLY SCARCE. Metalwork Colossus is lackluster as a big dumb beater; it won't be taking out players at the speed of Blightsteel Colossus for sure. But it is big. More importantly, it can easily be free, or severely undercosted. Muzzio-ing for 7 is good, but doing it for 11 is way, way better. It also has a decent recursive ability, which additionally lets you dodge a return to dust and reanimate it. It's less about it being a beater, and more about it being an extremely efficient engine for muzzio, at least in my opinion.

It very will can be a efficient engine for Muzzio. I'd just need to figure out what to shift out to test Metalwork Colossus.
