Time for the sweetest deck I've brewed so far:
The main weakness of the deck is that it's slooooow and not terribly interactive. The sideboard is built to help that a lot, but it's still probably a bridge too far to be great except in a very warped metagame.
Next, we have several decks that are abusing the improvise mechanics and/or.... EGGS.
The main idea here is that if you can get a Foundry Inspector in play, you have 16 cards that cost 0 and draw a card on dying. Scrap Trawler and Pia's Revolution add to the value party, and Ravenous Intruder is your Atog of free sacrificio. Reckless Fireweaver and Key to the City allow you to turn these into victory. The main concern I have here is that we don't have enough redundancy and, though the combo pieces more or less function independently, so you don't need all of them, I'm not sure if they're good enough by themselves. The mana base is also very confusing, because you have a bajillion cantripping eggs.

Maybe my most hopeful for the archetype in general is this: https://www.mtggoldfish.com/deck/551382#online
I'm pretty sure Herald of Anguish is the real deal. RB Gives us lots of sac outlets to give us some reliability there. Scrapheap Scrounger allows us to have lots of fodder over and over. Unlicensed Disintegration is just a very good removal spell. We get some pretty decent ability to go grindy out of the board as well.
