May need a in the activation cost as well; not sure. Throwing to the committee.

I don't think it needs it.

Vintage!

Super amusing funtimes in some kind of weird Esper deck await this. But I think it's OK.

Yeah, I really can't imagine this is breaking anything that Metalworker and Mishra's Workshop haven't already broken to tiny little bits.

And in non-Legacy formats, Affinity decks have already won or burnt out by the time they hit 5 mana.

But Sharuum EDH will love this to supplement Ashnod's Altar for more stupid combos.

More like Krark-Clan Ironworks. I suspect Wizards wouldn't want to print another KCI, but I could be wrong. I guess they printed Grand Architect which is somewhat similar.

KCI isn't banned, and restricting the mana for artifacts only means you can't loop to build up game-ending Fireballs or whatever one would do.

So I guess that begs the question, "Is it worth giving this another ability?" Flying, with the stipulation that the artwork show a machine hovering over a scrap pile?

I know reading it might seem weird but I can only think of it saying "another" artifact.

What if it had Shroud and the flavor text would be, "How do we get it to stop?"
