Looks good so far my friend!

Some suggestions I have for you:

Krark-Clan Ironworks - easily the most important card in my deck. It is just phenomenal.

Nim Deathmantle - lots of fun. I wondered why everyone kept suggesting it, and when I played with it I understood why. If you want to go infinite, that is a possibility with Nim!

Scourglass - Super helpful if you want to destroy the majority of your opponent's things and not yours. Could potentially replace Nevinyrral's Disk, depending on your opponent.

Other suggestions: Skullclamp, Erratic Portal, Magister Sphinx, Kuldotha Forgemaster

Personally, I think Padeem, Consul of Innovation is a little overrated. Sure, you could potentially draw an additional card on your upkeep and your artifacts have hexproof but I just think there are better ways for card draw and protection. I also think Ethersworn Adjudicator is a little more expensive than he's worth, but that's just from experience. I've played with him and didn't find him very useful, but he is versatile.

I hope that helps! Looks like a lot of fun so far!

Eldrazi Displacer opens up a lot of degenerate combos with the help of Ashnod's Altar / Krark-Clan Ironworks. I also find only running Disciple of the Vault to be a it weak, as it is difficult to recur/search out. I highly recommend running Purphoros, God of the Forge and Altar of the Brood for some additional redundancy to your combos. The latter especially so, as it is easily found with a majority of tutors and makes Trinket Mage even more of a powerhouse in this deck. Lastly, Whir of Invention is one of the most bonkers tutor I've seen come out for artifact decks, so if you can find the room for it, I'd highly recommend it.

As for what I would cut for these cards, Filigree Angel simply doesn't provide enough for its heavy CMC as does Noxious Gearhulk. Unless I'm missing something, Saheeli's Artistry sounds like an expensive win-more card, which while fun doesn't seem to do that much in terms of actually closing out the game for you. It also seems like you don't have enough support to justify running Memnarch in my opinion, as you don't have that many rocks to get him out quickly nor a Mycosynth Lattice to vastly accelerate the rate at which you can steal your opponent's stuff.

Anyway, these are just my suggestions and as always the most important thing is for you to run a deck that you find fun. Hopefully you'll find some of my suggestions helpful though.

I like to run 1 cloudshift it's great with all the etc effects you have going on. It also can catch your op off guard.

Teal_Fox - I originally had Eldrazi Displacer in the list, but I was worried about if I would have enough sources to generate the colorless mana for his ability in a deck running four colors. Still not sure if I have enough for that, but I will definitely pay close attention to see if it is right to bring him back into the list. Purphoros, God of the Forge is a very solid suggestion, I will see what I can do about getting him in here. He will never be a creature, but I think that is okay. Altar of the Brood may come in if I do end up putting Trinket Mage in. I don't know how I forgot about Whir of Invention.

As to your points on what to take out, I think Saheeli's Artistry is a possibility, as is Memnarch. It is true that I don't have ways to really abuse Memnarch as the list stands now, and your points on Saheeli's Artistry are valid. I have had very good luck with both Filigree Angel and Noxious Gearhulk, but if I were to remove one, I think the angel gets the boot here. It's possibly true that the ability is only good if I am already ahead, so I think I am going to try replacing it and seeing if I miss it. Noxious Gearhulk has proved itself to be very worthwhile, however - he helps cut down a scary opponent while being a sizable body on my board at the same time. He's also very nice to pair with Deadeye Navigator.

Last thing, what are your thoughts on Hanna, Ship's Navigator in this list?

Zombot - Cloudshift could work, however I would need to find a slot for it where I think it is truly better than what I am removing for it. I will look at the list and see what I can find. What would be your cut, other than things listed above, as those slots will probably be filled with recommendations from Teal_Fox

Eldrazi Displacer is best seen as a combo piece, so you only really drop it when you have the pieces necessary to win. Mainly, you would be using it with Krark-Clan Ironworks/Ashnod's Altar to get infinite ETB/Death Triggers. Even if you don't add it in, I would highly recommend finding room for Ashnod's Altar, as the added redundancy is crucial for a number of the combos you already have in the deck.

Personally, I find Hanna, Ship's Navigator too slow to consider running in even a half-serious list. While capable of generating loads of value if not instantly removed, you have access to far stronger recursion options like Scrap Mastery and Daretti, Scrap Savant.

Teal_Fox - Thanks for the input. I'll keep it in mind as I work on my next set of updates to the list!

Looks amazing! I'd just maybe swap Combustible Gearhulk with Trinket Mage(that is in your maybeboard, right?), netting Sol Ring/Skullclamp/maybe capsules early on can be pretty good.

Was looking at the list that you have and thought I'd suggest Mana Echoes, Panharmonicon, Phyrexian Altar and/or Ashnod's Altar?

ojayaba - Not sure Mana Echoes does anything all that impressive here. Artifact is a super type, so that isn't a shared subtype for Mana Echoes. Phyrexian Altar and Ashnod's Altar are definitely things I am considering and Panharmonicon is another good suggestion. I'll toy around with these things and see where they might fit. Thanks for the suggestions!

Artifact is a type yes, but every creature(excluding a morph, manifest and a few others) has a subtype such as Breya's Thopter tokens. With just breya and her entourage of two thopter soldiers you gain 5 colourless mana(1 for breya herself, then 2 per thopter token trigger). If you happen to have any thopters left from other castings, then you will net more mana.

ojayaba - Okay, I see where you're coming from now. It's possibly worthwhile. I'll see if it can work its way into a spot here, thanks for the pointer.
