Mox Opal Discussion

Chasmolinker on So, You Want to Play Lantern Yea (Budget)

Much appreciated feedback! I've never played the deck myself, but I have played against it. The core of the deck is very affordable at ~$75 or less. It's the pieces that keep the deck competitive that really kill any attempt at a competitive budget build. AKA Mox Opal and Ensnaring Bridge .

I know the builds before Whir of Invention was printed were mostly GB shells. I agree that having more fog effects could replace Ghostly Prison . It would help make room for that one of Ensnaring Bridge too.

Okay lets break down the justifications you gave, because I still think they merit changing.

Choosing not to run Mishra's Workshop in a deck that combos and staxs with artifacts is just silly. The problem is far more with your deck building choices of running 20 artifacts in an artifact commander oriented deck than the card itself. I shouldn't have to explain the value of 3 extra mana going towards your paradox engine or a stax piece like trinisphere, but apparently I do. Getting to winning pieces faster is better, run it. You also have the luxury of a mulligan on hands when its dead, similar to how Gaea's Cradle is a great card but dead in some hands.

Seat of the Synod combos with Mox Opal Transmute Artifact Inventors' Fair Reshape Unwinding Clock and is pullable for X=0 from Tezzeret the Seeker or Whir of Invention , meaning you can ramp in mono blue. Also recoverable from GY with Academy Ruins . Meanwhile, it nonbos with Back to Basics . Do some cost/benefit analysis and come back to me on that one.

Expedition Map is tutor density, which is your single biggest problem. If you are in a creature heavy meta, it functions as Tabernacle #2, why would you not run it? The value engine with Academy Ruins is icing on the cake. It's also part of a tutor chain using Inventors' Fair which leads to winning lines. Calling it cute without realizing it gives you more consistency with another winning line that also grinds value is just ignorant. Similar to Seat of the Synod , look at your own cards before rejecting inclusions.

Legacy's Allure is 100% a bad card. Assuming you somehow land that on turn 1, it still isn't anywhere close to live until turn 3. Unless the opposing creature is already on the board turn 1, your opponent will remove it before they play whatever creature they need that you would steal anyways, and if the creature is on the board turn 1 you should remove it before turn 3 anyways. Many stax creatures are symmetrical, so stealing one does nothing because those decks are designed to work around the effects. Also Gitrog is a 6/6 so assuming turn 1 Allure it still won't be live until turn 7, at which point Gitrog has already won. You can make the argument for proliferate, but you aren't running any. Aether Spellbomb is faster, combos with your commander, can turn itself into a cantrip if there aren't good creature targets, synergizes with that giant list of cards I talked about with Seat of the Synod, and is less color intensive. If you really need another theft effect, Vedalken Shackles is significantly better and combos all the same ways.

Howling Mine grinds values in longer games. Even if you give your opponent 1 or 2 cards, if you end up drawing 6 or 7 cards from it you are getting a better advantage. It works better in a stax build over a combo build, but then that leads to my next point. If you're really scared run Blinkmoth Well

You should build this as a stax deck. Compare this to an Arcum Dagson deck. The reason that is able to be a fast combo deck is because it has a tutor in the command zone that leads to winning lines. Meanwhile, Urza generates mana and expensive card advantage from the command zone, which benefits you when games go longer. Why would anyone build this deck with these pieces when Arcum does the same thing but better? They are the same CMC, but Dagson is less color intensive so its easier to ramp into with mono blue.

Even if you are trying to run this as fast combo, you aren't making good choices. Why are you running Fact or Fiction and not Frantic Search ? Why is your counterspell density so high when you should be tutoring or drawing to win? 13 counterspells with the meme new Narset spell for 14? Why? The card advantage your deck generates isn't high enough to sustain a package that big. If you're trying to fast combo why are you focusing on playing defensive? You don't need that many counterspells to protect your own combo.

Why are you running Power Artifact but not Basalt Monolith ? Otherwise power artifact is literally a dead draw if Grim Monolith is gone or unavailable. It opens up more options to get infinite and win with Urza

Cut Future Sight . Focus on assembling infinite mana to use Urza as an outlet. Not a single cEDH list runs it for a reason, expensive and slow. If you have infinite mana to plow through your deck with Future Sight you can just do the same with Urza. Wasted slot.

Running Isochron Scepter Dramatic Reversal and Copy Artifact but you aren't running Winds of Rebuke . It has high value outside combo, and high value inside combo. Currently you only have one method of drawing deck outside Urza (Paradox + Voltaic Key + Sensei's Top), which means you are very liable to be hit with Meddling Mage or Pithing Needle or Phyrexian Revoker or Cursed Totem , all of which see play and make your Jace and Labman into dead draws. You should also consider Blue Sun's Zenith for similar reasons, gives an outlet for infinite mana if Urza is turned off or unavailable.

How about Chrome Mox , Mox Opal , Mox Diamond , Mana Vault , Mana Crypt and Sensei's Divining Top instead of the janky equipments? Also, I would probably run stuff like Mana Drain , Force of Will , Swan Song , Pact of Negation and the new Force of Negation in a mono blue combo deck like this (if money is not an issue).

You can also add Intuition and Reconstruction so you have an additional tutor to search for your artifact combo pieces. (Search for Reconstruction , Buried Ruin / Academy Ruins and the combo piece.) Good thing about these cards is that they are also useful on their own.

Tolaria West can be a useful tool to tutor for specific lands or your zero mana stuff (especially usefull if you add pact of negation).

I’ve updated the deck a bit! I wanted to include Mox Opal , as well as a couple of the 100$+ mana rocks, but since Urza himself makes every artifact into mana rocks, while it would work, it’s one of the optional additions. I’ve also been contemplating replacing Scroll Rack since Urza’s third ability forces a shuffle in the first place, but I’ll wait until Modern Horizons is fully spoiled before I do that (at this rate, you never know what else is in it). Reshape is a good one too, must have passed by that. And for the lands, something like Blood Moon can be worked around or bounced, but Stony Silence and other ability nullifiers are definitely weakness to all Urza decks - I have to find more removal in Blue to replace existing cards in the deck.

I highly suggest Mox Opal if you have access to it. In artifacts matter decks like this, it's a powerful source of early ramp.

I'm not sure how good Seat of the Synod is. It is an artifact, but it also straight dies to Null Rod , Back to Basics , Stony Silence and Blood Moon . I don't know how big your meta is on non-basic hate, but in mine Seat might as well be a Darksteel Relic . I think a basic would be better.

I never had much luck with the Pili-Pala combo. Does it work for you? I would just as soon run more tutors like Reshape or Transmute Artifact . You might also consider Power Artifact on Basalt Monolith or Grim Monolith ... that'll depend on how much money you want to spend though.

If you're looking for control elements, consider Counterbalance . With Sensei's Divining Top and Scroll Rack , it is a powerful card.

I agree with DonQuijote: Jace, Wielder of Mysteries is a good win condition. Once you've gotten rid of your library and have infinite mana, he wins.

If you'd like, I'd highly recommend Howling Mine since you can tap it on their turn, preventing them from drawing an extra card.

Additionally, stax pieces like Winter Orb can also be manipulated. Cards like Chrome Mox and Mox Opal have zero downside.
