Multiverse Reforged is not a normal four-color value precon.
Led by Jace, Multiverse Architect, the Reality Fracture Commander deck wants to create inexpensive creature tokens and then transform those expendable bodies into some of the most expensive creatures in the deck. Instead of paying eight mana for Archon of Cruelty, the plan is to turn a 1/1 token into it.
That gives this precon a very unusual upgrade rule: do not automatically add cheap utility creatures just because they are good Commander cards. Every small creature or planeswalker you add becomes another possible hit for Jace’s −3 and can make the entire engine less reliable.
The strongest Multiverse Reforged upgrade therefore doubles down on token production, adds more Polymorph effects and improves the quality of the enormous creatures waiting at the top of the library.
How Jace, Multiverse Architect Actually Works
Jace, Multiverse Architect costs and can be your commander despite being a planeswalker.
His static ability also provides unusual protection. At the beginning of combat on each opponent’s turn, that player may pay . If they do not, creatures they control cannot attack Jaces you control that turn.
His +1 draws two cards and then puts one card from your hand on the bottom of your library. That is particularly useful here because drawing one of your giant Polymorph targets is often undesirable. Jace can put the expensive creature back into the library where his −3 can find it later.
The −3 is the real engine. Exile another creature or planeswalker you control, reveal cards until you find a creature or planeswalker, put it directly onto the battlefield and put everything else on the bottom randomly.
Turning a disposable 1/1 into Archon of Cruelty is exactly what this deck wants to do.
The Stock Deck Already Understands the Assignment
Wizards built Multiverse Reforged around Jace surprisingly well.
Skrelv’s Hive produces a steady stream of Phyrexian Mites, Dreadhorde Invasion creates and grows an Army, Lingering Souls can produce four flying bodies across two casts, and Secure the Wastes can generate an entire battlefield at instant speed.
Kher Keep is particularly useful because the token engine occupies a land slot rather than a spell slot. Grand Crescendo can simultaneously protect your battlefield and create more creatures, while Shark Typhoon turns the deck’s noncreature spells into flying Polymorph fodder.
Then there are the hits.
Archon of Cruelty, Serra’s Emissary, Avacyn, Angel of Horror, Darksteel Angel, Memnarch, the Warden and several of Reality Fracture’s Echoverse legends give Jace plenty of powerful permanents to find.
The basic structure is already correct. We just want to make it considerably more consistent.
Best Multiverse Reforged Upgrades
Oath of Teferi is one of my favorite upgrades because it improves Jace without contaminating the Polymorph pool. It allows you to activate planeswalker loyalty abilities twice during each of your turns.
That means Jace can +1 to draw and filter cards, then −3 on the same turn to transform a token. It also works with other planeswalkers that remain in the list.
Bitterblossom gives the deck another repeatable token generator without adding a creature card to the library. One life per upkeep is a small price for a constant supply of flying 1/1 Faeries that can either attack, block or become Jace fuel.
Polymorph gives the deck another version of its commander’s central effect. Turning a token into the next creature in your library means the deck can keep cheating monsters into play even when Jace is removed.
Transmogrify performs almost the same job in red. Redundancy is extremely valuable here because opponents will quickly understand what Jace is capable of and are unlikely to leave him alone forever.
Finally, Hoarding Broodlord is the sort of creature worth adding to the Polymorph pool. It costs eight mana normally, but if Jace finds it for free you get an 8/6 flying Demon with an enters ability that searches your library for any card and exiles it face down, allowing you to play it later. That is exactly the profile we want from a hit: expensive to cast fairly, devastating when cheated into play.
What Should You Cut?
The first creatures I would remove are not necessarily bad Magic cards. They are simply disappointing outcomes when you sacrifice a token and spend three loyalty on Jace.
Dack Fayden, Helping Hand is flavorful but does not offer the same immediate impact as the best targets. Ginger, Queen of Sweets is another interesting Echoverse legend that becomes less appealing when compared directly with Archon of Cruelty or the deck’s other premium hits.
The Ur-Sphinx has a much more attractive home leading its own Sphinx deck than serving as a random Polymorph result here. Multiverse Reforged simply does not contain enough Sphinx support to maximize what makes the card distinctive.
Teferi’s Reproach is politically interesting but does not advance the primary engine, while Brainsurge is reasonable card selection in a deck that already receives excellent hand filtering from Jace himself.
My first five changes would therefore be:
Out: Dack Fayden, Helping Hand, Ginger, Queen of Sweets, The Ur-Sphinx, Teferi’s Reproach, Brainsurge
In: Oath of Teferi, Bitterblossom, Polymorph, Transmogrify, Hoarding Broodlord
That simultaneously improves token production, gives us more copies of the deck’s primary effect and raises the average quality of the creatures Jace can find.
Do Not Add Normal Utility Creatures
This is probably the most important deck-building lesson in the entire guide.
In most Commander decks, adding something like a cheap mana creature, value creature or creature-based removal spell is completely reasonable.
Here it can actively make the deck worse.
Imagine sacrificing a 1/1 token to Jace expecting Archon of Cruelty and revealing a two-mana utility creature instead. You have spent three loyalty and a permanent to put something onto the battlefield you could have simply cast from your hand.
The same warning applies to planeswalkers because Jace’s −3 can reveal either a creature or a planeswalker.
That does not mean the deck can never play another planeswalker. It means every creature and planeswalker added to the library needs to pass a much higher test than usual.
Would you be happy to spend Jace’s −3 and sacrifice a token to put this card directly onto the battlefield?
If the answer is no, it probably should not be in this version of the deck.
Brainstorm Is Much Better Here Than It Looks
The stock Brainstorm is particularly valuable because drawing your giant creatures is actually a problem.
A Polymorph effect can only find a creature that is still in the library. If Archon of Cruelty or another premium target is stuck in your hand, you may not have a realistic way to cast it for several turns.
Brainstorm allows you to put those expensive cards back on top of your library.
Jace’s +1 solves the same problem slightly differently by drawing two and putting one card from your hand on the bottom.
This is one of the rare Commander decks where putting a powerful card back into your library can be significantly better than keeping it in your hand.
Token Generators Are the Real Engine
The best token generator here is not necessarily the card that creates the most creatures.
Repeatability matters more.
Skrelv’s Hive gives you another body every upkeep. Dreadhorde Invasion keeps supplying an Army. Bitterblossom provides another creature every turn.
That means Jace can repeatedly exchange something cheap for something enormous without requiring another card from your hand each time.
Large one-shot effects such as Secure the Wastes and Grand Crescendo remain excellent because the unused tokens can still attack or protect Jace.
The important part is that these engines are not creature cards themselves.
They build the battlefield without making the next Polymorph worse.
Mass Polymorph Can End Games
The stock Mass Polymorph takes the deck’s primary plan to its logical extreme.
Instead of transforming one creature, it exiles every creature you control and reveals cards from the library until you reveal that many creature cards, putting all of them onto the battlefield.
If your battlefield contains four disposable tokens, that can suddenly become four enormous creatures.
The downside is obvious: you are committing heavily into one spell and may expose yourself to a sweeper afterward. But the ceiling is high enough that Mass Polymorph remains one of the strongest reasons not to dilute the deck with small creatures.
If every creature in your library is terrifying, Mass Polymorph becomes terrifying too.
Improve the Four-Color Mana Base Gradually
Jace costs , which means the deck needs all four colors by the time it reaches five mana.
Fortunately, the stock precon starts from a surprisingly respectable position. Command Tower, Reflecting Pool, Exotic Orchard, Fabled Passage, multiple pain lands and several check lands already provide useful fixing.
The ramp package is also substantial. Sol Ring, Arcane Signet, Fellwar Stone and a large collection of Signets and Talismans help fix several colors while accelerating Jace.
I would therefore improve the mana base gradually rather than spending the entire upgrade budget on premium lands.
Our Mana Base Upgrade Guide covers exactly this situation: replacing the weakest fixing first instead of assuming every four-color Commander deck immediately needs fetchlands and shock lands.
The objective is simple. Jace needs four different colors, and a hand that produces six total mana but cannot produce still cannot cast your commander.
How the Upgraded Multiverse Reforged Deck Wins
The ideal opening does not involve casting any of your enormous creatures.
Develop your mana, establish a token engine such as Skrelv’s Hive, Dreadhorde Invasion or Bitterblossom, and get Jace, Multiverse Architect onto the battlefield.
Then start rewriting reality.
A disposable token becomes Archon of Cruelty. Another can become Darksteel Angel. Polymorph and Transmogrify keep the engine working without Jace, while Mass Polymorph can convert an entire token army into the top end of your deck at once.
Oath of Teferi makes Jace dramatically more efficient by allowing two loyalty activations per turn, and his +1 helps recycle expensive creatures accidentally drawn into your hand.
Eventually the deck reaches the point where every tiny creature represents the possibility of something vastly more dangerous.
That uncertainty is one of Multiverse Reforged’s greatest strengths.
Your opponent does not need to be afraid of the 1/1 token.
They need to be afraid of what Jace is about to turn it into.
PreconForge Verdict
Multiverse Reforged already has a remarkably coherent identity straight out of the box. Wizards built the deck around cheap token production, Polymorph effects and deliberately expensive creatures, so the correct upgrade is not to replace that structure.
It is to make it more reliable.
Bitterblossom gives Jace another renewable supply of targets. Polymorph and Transmogrify add redundancy. Oath of Teferi dramatically improves Jace himself, and Hoarding Broodlord upgrades the quality of the creature pool.
Most importantly, resist the urge to fill the deck with cheap utility creatures.
Multiverse Reforged works because the bottom of the curve creates expendable tokens while the top of the curve contains monsters you were never supposed to cast fairly.
If you are new to tuning preconstructed decks, our How to Build a Commander Deck guide explains why card roles and ratios matter more than simply replacing every inexpensive card with something stronger.
For Jace, that principle is taken to the extreme.
Make something worthless. Turn it into something terrifying. Repeat.
