Very cool deck! Curious how The Mightstone and Weakstone  Meld works in the deck when you get to playtest it!

This looks pretty cool. I think you could even cut two lands. I've recently built Chiss-Goria, Forge Tyrant, and I included some cards there you might want to consider.

The Mightstone and Weakstone  Meld is surprisingly powerful. Putting a big mana rock downlate in the game can feel bad, but this thing can double as card draw or removal.

Slobad, Iron Goblin is a nifty little mana source.

With all those artifacts, Dragonspark Reactor can deal quite a bit of damage.

And Scarecrone is a reanimator card many forget about.

Hey, some interesting card choices for upgrades to the precon. I can tell your deck is based on the precon because I see Darksteel Juggernaut.

A kink here to work on is the avg. CMC. The mana curve is very high at 4.3 not including Organic Extinction and Mycosynth Golem. The precon mana curve is already high at 3.5 not including Thought Monitor. A higher mana curve would be fine if supported with lots more low mana cost ramp, but you cut most of the low mana cost ramp (Signets, Liquimetal, Vessel) from the precon. There's only 6 ramp sources here 3 CMC or less which is low.

You could have a difficult time casting Urza using artifact creature affinity with only 7 artifact creatures 3 CMC or less. You really can't count on Urza's artifact affinity to first cast him and having not many ramp sources, ramp can't be counted on either. Master Transmuter is a great upgrade, she helps a lot when playing a lower amount of ramp. To improve the mana curve which will help gameplay consider choosing a few of the better high mana cost cards and cutting the others? Most 4 drops here are much better than the 5-7+ drops and that's good for the mana curve.

Research Thief, The Mightstone and Weakstone  Meld, Blightsteel Colossus, Mycosynth Golem, Thopter Assembly, Tezzeret, Master of the Bridge, Organic Extinction, Darksteel Forge, Mycosynth Lattice, Kuldotha Forgemaster, Cyberdrive Awakener these are the better 5-7 CMC cards here. The others could be cut to lower the mana curve because they're simply not as good as these.

  • Thief, it's repeatable draw effect is good when you want to be attacking with Constructs.
  • Weakstone because you have Urza, Lord Protector  Meld.
  • Blightsteel, best secondary attacker and because you have Master Transmuter.
  • Golem because Urza is a consistent way to create artifacts.
  • Assembly because you have Time Sieve.
  • Tezzeret because of Constructs.
  • Extinction because of Constructs.
  • Forge, best protection for all artifacts and because you have Lattice, Transmuter and Padeem.
  • Awakener flying for Constructs.

Some upgrades at your price point to consider:

Good luck with your deck.

I saw your post about The Mightstone and Weakstone  Meld color identity and wanted to share this:

A meld card's color identity only cares about the front face. Here is the ruling from The Mightstone and Weakstone  Meld Gatherer page:

10/14/2022 In the Commander variant, a meld card’s color identity is determined only by the mana costs and mana symbols in the rules text of its front face. No symbols or rules text of the permanent it melds into are considered.

Max_Hammer I will test more with the Myr Turbine too see if I can drop the number to 2. The fact is that card becomes good once battlesphere hit the battlefield , the 4 token generation makes the tutor easier to play. On top of that Forsaken Monument alone makes the tokens 3/3. I thought of The Mightstone and Weakstone  Meld as versatile card for his removal / draw when it hits the battlefield plus its ability to generate mana helps to no rely purely on tron. Sculpting Steel can be used to chose again one of the 2 effects at 3 cost . I will try to play without basic lands but I dont know it will be a good choice, everyone i'm playin with plays boseiju at least ahahha. Nephalia Academy looks good! THanks again for your comment!

Coward_Token - You right. I always thought it said "opponent"...that is unfortunate. On the good news side of things. Supposedly The Commander RC are ruling that Urza, Lord Protector and The Mightstone and Weakstone have "partner with" so feel free to run them together. I'll have to track down the article my friend showed me last night.

The worst thing about Urza, Lord Protector as a commander is that it doesn't partner with The Mightstone and Weakstone, so if the latter gets exiled you're kinda stuck with a bad Grand Arbiter Augustin IV. I think it's still seems pretty fun though. Maybe go for a lot of 1-mana artifacts?
