Ancient Tomb/
City of Traitors: Sol lands are insane. 2 colorless mana is quite good. Being able to play a
Chalice of the Void on turn one for 1 is kinda how you win games. These two lands serve as the best accelerators for Tezzerator. Some people like to play a split of these guys but I prefer to just run a simple 4 Tombs and call it good.
Mox Diamond: Moxen are always nuts. This one allows you to be quite explosive and fixes our mana.
Dimir Signet/Talisman of Dominance: Mana rocks! Ever wanted to have 4 mana available turn 2? Try Tomb/City into Signet/Talisman into T2 land drop into Tezzeret! These are nice little accelerators that turn into fodder late game for Daretti and Transmute Artifact.
Izzet Signet: This is a signet to run if you are running a heavy red splash or feel like you need more red sources.
Academy Ruins: Recurring artifacts? In an artifact deck? Whaaaaaaaaat? Yeah, unsurprisingly this card functions very well in this list, buying back Baleful Strixes, Engineered Explosives and a wide plethora of nice little tools. Obviously a frequent target of Wasteland, this is still a land worth runnning, and since we run Crucible, it will be back later.
Inventors' Fair: Ok so this card reads as tutor for an artifact as long as you control three or more artifacts. Metalcraft, is that you? This card is quite convenient as it can find whatever piece of the puzzle we're missing while also providing some small life gain which is nice. Again, just like Academy Ruins is Wasteland bait, so is this, but again, we have Crucible of Worlds (Which also means we just recur a tutor effect...).
Dust Bowl/Wasteland: Because you have access to Crucible and can tutor it up at will, running land destruction like this isn't really hard to do and is sometimes quite helpful. If you run Blood Moon in the side, I wouldn't recommend this package, but if you don't I highly recommend trying it out, it's quite nice.
Tundra/Scrubland: When playing the white splash in this deck, I recommend a 1-1 split of Tundra and Scrubland. I personally don't like the white splash as I really love the Blood Moon sideboard and running 4 colors will prevent you from doing it.
Seat of the Synod/Vault of Whispers: A land that you can find off of Tezzeret, Agent of Bolas' +1, a land you can tutor and put into play off of Tezzeret the Seeker 's -0, and a land you can sacrifice to Daretti, Ingenious Iconoclast's -1 or Thopter Foundry. Yeah, I'm sold. ((Note: Currently not playing these to make room for my precious Blood Moon))
Island/Swamp/Mountain: If you are running Blood Moon in the sideboard, you want extra Islands and at least 1 Swamp. Thankfully you have mana rocks that produce colors, but it does help to be safe rather than sorry. At least 1 Mountain also helps vs Back to Basics and Wasteland to produce the red you sometimes need.
Polluted Delta/Bloodstained Mire/Scalding Tarn: Fetches are good. Who knew? Double blue is the most important color requirement, after which comes UB and RB. Polluted Delta is the better of the fetches as it gets you the Islands OR Swamp post board when you are working around your own Blood Moon. After that, I like Bloodstained Mire as the rest of the fetches, although I have been toying with Scalding Tarn but the relevance hasn't come up. I guess if you want the extra blue.
