Precon Upgrade Guide
Jace, Multiverse Architect Upgrade Guide
Reality Fracture ships one Commander deck, it is led by a planeswalker, and every creature in it costs six mana or more. The deck is built that way on purpose.
Reality Fracture
Multiverse Reforged
The polymorph never misses, but the uncastable top end and four-color mana make hands hard to keep and turns hard to plan. Out of the box, before any upgrades. How we rate precons
Buy Multiverse Reforged on TCGplayer →Quick verdict
Reality Fracture ships a single Commander deck, and it is the most single-minded precon in years. It is a polymorph deck: make a cheap, disposable body, then convert it into something enormous without ever paying for it. Out of the box it does the thing it says it does, because the deck is built so that the conversion can never miss. The same design is its weakness: the top end is uncastable, so a draw that finds the fatties instead of the converters is a hand full of cards you cannot cast yet.
Note the color identity: and nothing else. There is not one green card in the box, which is a joke the set makes on purpose. See the Echo section below.
TurnZero's own precon read rates Multiverse Reforged a 3 out of 5 on strength and a 4 out of 5 on difficulty. The polymorph plan works as printed, but the four-color mana and a top end you cannot cast mean it asks you to plan a turn ahead. See it alongside every other precon we cover on the precon directory.
The curve is the plan
Eighty-seven distinct cards carry an FRC collector number, and eighteen of them are creatures. The cheapest creature in the deck has a mana value of six. There is no two-drop and no three-drop, and only two creatures have a cheaper way in: Overlord of the Mistmoors's impending cost puts two 2/1 fliers on the board for four mana, and Akroma, Angel of Fury can be cast face down as a 2/2 for three. Both bodies are fuel for Jace. A precon curve that looked like this by accident would be unplayable.
It is not an accident. Five cards in the deck say some version of reveal cards from the top of your library until you reveal a creature card, then put it onto the battlefield. In a normal deck that effect is a lottery, and you flip into a mana dork as often as a threat. Here the library physically cannot produce a small creature, so every one of those effects resolves into a six-drop at worst and Memnarch, the Warden at best. The deck buys perfect consistency on its payoff by accepting that it will rarely cast one.
Mass Polymorph ↗
Exiles all your creatures, then finds that many creature cards and puts them onto the battlefield. Tokens count toward the number.
Synthetic Destiny ↗
The same effect at instant speed, resolving at the next end step. The deck's best answer to a board wipe.
Proteus Staff ↗
A repeatable, sorcery-speed version on an artifact. Bottoms the old body instead of exiling it.
Nissa, Leyline Tamer ↗
Draws on every land drop, and the first one each turn also digs out a creature and puts it into play.
How Jace works
Commander Spotlight
Jace, Multiverse Architect ↗
A five-mana planeswalker that starts on four loyalty and explicitly says it can be your commander. The +1 draws two and bottoms one; the −3 is a polymorph you can point at a token.
The line that matters is printed on the card: Jace, Multiverse Architect can be your commander. Planeswalkers need that sentence to lead a deck, and this is the first card in Reality Fracture to carry it. None of the planeswalkers in the main set do, including The Theorist, Jace Beleren.
The −3 is the engine, and the wording is worth reading slowly: it exiles another target planeswalker or creature you control, then digs a creature or planeswalker out of your library and onto the battlefield. Nothing says the exiled permanent has to be worth anything. Point it at a 1/1 Spirit token and you have traded a token for an eight-drop. That is the cheapest polymorph rate in the format, and it is why the deck is packed with cards that make one small body per turn.
Starting loyalty is four, so the −3 is live the turn Jace lands. The +1 (draw two, bottom one) is how you climb back to using it again, and bottoming a fatty you can't cast is a genuine upside rather than a cost. The static ability taxes each opponent {2} to attack Jaces you control, which is a real protection tax in a format where the table's first instinct is to swing at a planeswalker commander.
How the precon plays
Turns one through four are spent making tokens and holding removal. The deck has a deep bench of cards that produce a body for cheap, and in this deck a body is polymorph ammunition more than a blocker. Kher Keep is the easiest to overlook, because a land that makes a 0/1 Kobold every turn for {1}{R} feeds Jace's −3 for the whole game.
Kher Keep ↗
Pay {1}{R} and tap it for a 0/1 Kobold token, every turn. Repeatable ammunition for the −3 in a slot you were already spending on a land.
Staff of the Storyteller ↗
A Spirit on entry, then draws cards as the deck keeps making tokens.
Lingering Souls ↗
Four flying bodies across two casts, which means four separate conversions.
Skrelv's Hive ↗
One Phyrexian Mite per upkeep, which is exactly one −3 activation per turn cycle.
Occult Epiphany ↗
Refills the hand and makes a Spirit for each card type discarded along the way.
Shark Typhoon ↗
Cycles for a flying body at instant speed, or sits and makes one per noncreature spell.
Then the payoffs land. Archon of Cruelty is the best hit in the box. It strips a card, drains life and eats a creature the moment it arrives, so it pays off even if it dies immediately. Avacyn, Angel of Horror makes the deck's own destroy effects one-sided: Martial Coup, White Sun's Twilight and Elspeth's −3 kill your nontoken creatures too, and Avacyn returns them at the next end step. She does nothing for the polymorph effects, because those exile. Serra's Emissary naming "creature" or "sorcery" shuts an opposing deck off a whole axis of attack.
Archon of Cruelty ↗
The highest-value hit in the deck. Sacrifice, discard, drain and draw, all on arrival.
Avacyn, Angel of Horror ↗
Flying deathtouch that returns your nontoken creatures at the next end step when they die. Exile is not dying, so pair her with the destroy wipes, not the polymorphs.
Serra's Emissary ↗
Protection from a card type of your choice, for you and your whole board.
Archfiend of Despair ↗
Shuts off opposing life gain, and at each end step every opponent loses as much life again as they lost that turn.
Every new card is an Echo
Eighteen cards in the deck are new, and all of them are Echo variants. The set's conceit is that Jace has rewritten familiar characters into the wrong colors. It is worth pointing at during a game, because the deck reads as nonsense until you know the premise.
The joke lands hardest on the manabase: this is a deck containing both Nissa, Leyline Tamer and Omnath, Locus of the Void that cannot cast a green spell, because neither of them is green any more. For the full picture of what the set did to the rest of the multiverse, see the Reality Fracture set guide →.
What works out of the box
Jace, Multiverse Architect ↗
A commander that converts a worthless token into your best card, and taxes the table for attacking him.
Archon of Cruelty ↗
Every polymorph deck wants a hit that pays off on arrival. This is the one.
Synthetic Destiny ↗
Instant speed turns it from a combo piece into a board wipe answer that profits.
Swords to Plowshares ↗
Premium removal, and the deck's manabase supports it on turn one.
Sunfall ↗
A wipe the deck recovers from faster than anyone else at the table, since its threats come off the top.
Flawless Maneuver ↗
Often free, and protects a board you spent several conversions assembling.
Niv-Mizzet, Ghost Counsel ↗
Its tap drains 1 and gains you 1, which triggers its own draw. That is a card a turn by itself, and a 4/4 Angel a turn with Ob Nixilis out.
What needs improvement
The dead-draw problem is real and the deck does not fully solve it. Eighteen six-plus-drops in a hundred cards means roughly one card in six is something you would rather find with a polymorph than in your opening hand. The deck's own filtering (Brainsurge, Fact or Fiction, Jace's +1) helps, but adding cheap card selection is the highest-leverage upgrade this list can take.
Token production is thinner than the plan wants. Several of the enablers make exactly one body and stop. A polymorph deck wants a body every turn so the −3 never sits idle, and the cheapest way to buy that is a permanent that keeps producing. The box already has a few: Kher Keep, Skrelv's Hive, Windcrag Siege on its Jeskai mode (a Goblin every upkeep), Elspeth, Sun's Champion (three Soldiers per +1) and Dreadhorde Invasion. The Army it makes looks like the wrong shape for a deck that counts bodies, but exile it with the −3 and the next upkeep makes a fresh one, so it feeds Jace every turn for two mana. Keep all of them.
The deck runs too much mana, not too little. It ships with 39 lands and 13 mana rocks, which is 52 mana sources in a 100-card deck. The usual Commander baseline is 36 to 38 lands and about ten ramp pieces, and a deck of seven-drops can sit near the top of that range, but not this far above it. Fixing is not the problem either: the three new Turbulent Shore-style duals enter untapped once your opponents control eight or more lands between them, which in a four-player game is usually turn three. That is why three rocks and two lands are among the cuts below. See the Land & Mana Base Guide → for how to set the count.
10 cards to cut
One rule before the list: do not let the creature count drop. Every creature you remove is a hit the polymorph effects can no longer find. Three of the cuts below are creatures, and the better-hits tier of the upgrades puts three creatures back.
The Ur-Sphinx has eminence that discounts other Sphinx spells, and it is the only Sphinx in the deck. That leaves a nine-mana body with no arrival trigger that has to survive a turn and attack before it does anything.
Dack Fayden, Helping Hand pulls creature cards out of your library and hands them to your opponents. They are goaded, so they have to attack someone other than you, but in a deck whose library is its hand, that is spending the resource you least want to spend.
Omnath, Locus of the Void is a seven-mana body with no arrival trigger and no evasion. As a polymorph hit it asks the table politely to deal with it.
Teferi's Reproach makes one opponent untouchable for a turn. It is a political card in a deck with no political plan, and it does not advance the conversion game at all.
Fellwar Stone only makes the colors your opponents' lands can make. Exotic Orchard already does that job from a land slot, and in a four-color deck that needs a specific color on time, a rock that depends on the table is the first one to go.
Currency Converter loots for {2} and a tap, and turning each discarded card into a 2/2 takes another tap. Too slow for what it eventually does.
Cursed Mirror is a three-mana rock that only makes red, and its copy mode lasts until end of turn. In a deck with 52 mana sources it is the easiest rock to lose.
Talisman of Indulgence makes the same black-or-red pair as Rakdos Signet and pings you for it. With Cursed Mirror and Fellwar Stone also gone, the deck still runs ten rocks, which is plenty.
Restless Spire always enters tapped and makes two of your four colors. Thirty-nine lands is two more than the deck needs, and this is the slowest of them.
Sunken Ruins taps for colorless on its own and needs blue or black mana from another land before it filters. It makes the same two colors as Underground River and Drowned Catacomb, so it is the land you miss least. That leaves 37.
First upgrades
Ten out, ten in. The three better hits replace the three creatures cut above, and the other seven cards fill the seven noncreature slots. Prices are TCGplayer market prices as of October 26, 2026. The precon itself has no Game Changers. Rhystic Study and Teferi's Protection are both on the Game Changers list, so adding either one moves the deck from Bracket 2 to Bracket 3. If you skip the higher-investment tier, keep Teferi's Reproach, Fellwar Stone and Currency Converter in for now.
Budget: repeatable bodies and one more converter ($4.30)
Three of these produce a token every turn without being cast again, which is what keeps Jace's −3 online. None of them is a creature card, and that is deliberate. Young Pyromancer or Monastery Mentor would make the same tokens, but a two- or three-mana creature in the library is a creature the polymorph effects can flip into. Keep the token engines on enchantments and every reveal still finds a six-drop.
Transmogrify ↗
$0.86. Four mana to exile one of your tokens and reveal until you hit a creature card: one more polymorph, in red. It can also target an opponent's creature.
Metallurgic Summonings ↗
$2.36. An X/X Construct for every instant or sorcery, sized by the spell's mana value. The precon runs nineteen of them.
Assemble the Legion ↗
$0.34. One more hasty Soldier every upkeep than the last. Slow to start, then more bodies than Jace can use.
Mobilization ↗
$0.74. A 1/1 Soldier for three mana at instant speed, as often as you can pay. Spare mana at the end of an opponent's turn becomes ammunition.
Next: better hits ($6.36)
These replace the creatures cut above and keep the count where it was. A hit should change the board the instant it arrives, because it may not survive to your next turn. That means an enters trigger, not a cast trigger: a creature that says "when you cast" does nothing when a polymorph puts it onto the battlefield.
Agent of Treachery ↗
$5.50. Steals the best permanent on the table on arrival. A perfect polymorph payoff, and hard to cast at seven mana otherwise.
Grave Titan ↗
$0.34. Two 2/2 Zombies on arrival and two more each attack, so one hit hands Jace two more things to exile.
Ashen Rider ↗
$0.52. Exiles a permanent when it arrives and again when it dies, so it pays off through removal.
Higher-investment ($147.04)
Bitterblossom ↗
$32.38. The cleanest version of this deck's ammunition problem: one flying body every upkeep, forever, for two mana.
Teferi's Protection ↗
$46.87. Phases out your whole board, protecting a table's worth of conversions from one wipe. A Game Changer.
Rhystic Study ↗
$67.79. Cheap card flow to dilute the dead-draw problem, which is this deck's real weakness. A Game Changer.
Mistakes to avoid
Casting Mass Polymorph with more creatures than you have creature cards left. It exiles all of them first, then reveals until it finds that many creature cards. If the library runs out, those creatures are simply gone. Count before you cast it, especially late.
Holding Synthetic Destiny for your own turn. It is an instant. Cast it in response to a board wipe: your creatures are exiled before the wipe resolves, and at the next end step you reveal that many creature cards and put them onto the battlefield. Tokens count toward the number, so a board of 1/1s comes back as six-drops.
Exiling something good to Jace's −3. The ability does not care what you exile. A 0/1 Kobold from Kher Keep converts exactly as well as your Archon of Cruelty, and the Archon is already on the battlefield doing its job.
Forgetting Jace is not a creature. Mass Polymorph and Synthetic Destiny exile creatures you control, so your commander sits safely on the battlefield through both. The same is true of most of the table's creature wipes.
Who should buy this precon
A good fit for a player who likes a deck with one clear idea executed without compromise, and for anyone who has wanted to run a planeswalker as a commander since Commander 2018. It is also the rare precon whose gimmick survives the upgrade process: everything above makes it better at what it already does.
It is a poor fit for a player who wants to cast their big creatures the normal way, or for a table where games end before turn six. And be honest about the four-color manabase: this is not a deck to hand to someone playing their first game of Commander. For a deck-agnostic version of the upgrade order used here, see How to Upgrade a Commander Precon →.
