This is what I've been tinkering with. I have no idea if this is any good (I have a suspicion it will fall flat on its face), but I never have gotten the chance to try it out.
*Ignore the sideboard for the most part. I've given little thought to it.
2 Card Monte (idea)
The things you normally don't see in a 2 Card Monte list:
- Foundry Inspector
- Lodestone Golemn
In multiple match-ups, I lost because I was 1 mana short on certain turns. I kind of wondered, would an artifact cost reducer help in this deck like it does Ravager shops? Hard to say, but I felt and still feel it may be worth the try. This also adds the benefit of being an okay body (3/2). Which is something this deck can have trouble with, so buying a turn or two might be the difference between a win and a loss. Though, since this isn't really directly helping to pull off the combo, it very well could be a liability.
A great beat down body and with the main focus of this deck being artifacts, this can slow down an opponent. I think the body of the Lodestone helps tremendously and can impact a game. I'm quite less keen on this one and might be better as a Dark Confidant, Foundry Inspector, or maybe even a Tezzeret.
What I wanted was to get a little bit away from in the deck is being too all in on the combo, which is why I cut the draw 7 cards. The version I ran in the past, most likely due to my inexperience and misplays than the build (I trust @Shaman-Ben's deck building), I felt it fall on it's own face a lot and I was hoping to top deck. I wanted to shore up some of the weaknesses in that build, so I wanted to add a bit of a creature package (Lodestone Golemn, Foundry Inspector, Dark Confidant).
I flirted with unique 2 Card Monte ideas such things as: Phyrexian Revoker, Sphere of Resistance, Red Daretti, Thorn of Amethyst, Induced Amnesia, etc. (I'm sure there's more, but that's what I can think of right now). None of them felt right, except maybe, Induced Amnesia. I think Goblin Welder could be excellent and is probably the correct path for me to take, but I wanted to try an unique spin on the deck.
I'm not sure if changing to Pyroblast is correct for the deck. Mostly did it because I sold my Beta Pyroblasts. If I was running Dack Fayden, I would for sure play Pyroblast.
