Precon Upgrade Guide
Jace, Multiverse Architect Upgrade Guide
Reality Fracture ships one Commander deck, it is led by a planeswalker, and every single creature in it costs six mana or more. That is not a curve problem — it's the whole plan.
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. Its weakness is the mirror image of its strength — the top end is uncastable, so a draw that finds the fatties instead of the converters is a hand full of bricks.
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.
The curve is the point
Eighty-seven distinct cards carry an FRC collector number, and eighteen of them are creatures. The cheapest creature in the deck costs six mana. There is no two-drop, no three-drop, nothing to block with on turn four. 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 — 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 can never 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 not a blocker — it is polymorph ammunition. Kher Keep is the quiet standout, because a land that makes a free 0/1 Kobold every turn is a land that feeds Jace's −3 forever.
Kher Keep ↗
A land that makes a 0/1 Kobold token on demand. Repeatable, free ammunition for the −3.
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 — 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 quietly turns every later polymorph into a free one, because it returns your nontoken creatures when they die. 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 when they die. Makes the whole top end resilient.
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 drains every opponent for the damage they took 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 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.
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 single turn so the −3 never sits idle, and the cheapest way to buy that is a permanent that keeps producing.
Four colors is still four colors. Twenty-seven lands plus the signet and talisman package is a reasonable start, but the three new Turbulent Shore -style duals only enter untapped once an opponent controls eight or more lands, which is a late-game clause on an early-game problem. See the Land & Mana Base Guide → before spending anywhere else.
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. Four of the cuts below are creatures, and the upgrade section puts four 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. 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.
Niv-Mizzet, Ghost Counsel wants a life-gain engine the rest of the deck never builds, and does nothing the turn it arrives.
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.
Dreadhorde Invasion makes a single Army that grows rather than a stream of separate bodies. Effects here count bodies, not power, so one big Army is the wrong shape of token.
Currency Converter needs discard outlets and several turns of setup to produce one 2/2. Too slow for what it eventually does.
Cursed Mirror is a three-mana rock whose copy mode lasts until end of turn. The mana is fine; the card is replaceable by a rock that fixes all four colors.
Brainstorm is a famous card that needs shuffle effects to be more than a one-card rearrangement, and this deck has very few.
Windcrag Siege asks you to lock in one of two modes at a moment when the deck rarely knows which it wants, and neither mode is doing much for the conversion plan.
First upgrades
Budget: buy repeatable bodies
Each of these produces a token every turn without being cast again, which is precisely what keeps Jace's −3 online.
Young Pyromancer ↗
A 1/1 Elemental for every instant or sorcery, and this deck is mostly instants and sorceries.
Talrand, Sky Summoner ↗
The same deal in blue for a 2/2 flier, so the spare tokens can attack.
Ophiomancer ↗
A 1/1 deathtouch Snake every upkeep — one guaranteed conversion per turn cycle, and a real blocker if you don't use it.
Monastery Mentor ↗
A 1/1 Monk for every noncreature spell, which in this deck means several per turn once the mana is up.
Next: better hits
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.
Agent of Treachery ↗
Steals the best permanent on the table on arrival. Perfect polymorph payoff, unplayable at seven mana otherwise.
Etali, Primal Conqueror ↗
Casts free spells off the top of every library when it attacks, and has a second life as a removal spell.
Sheoldred, Whispering One ↗
Reanimates for you and strips the table every turn it survives.
Ashen Rider ↗
Exiles a permanent when it arrives and again when it dies, so it pays off through removal.
Higher-investment
Bitterblossom ↗
The cleanest version of this deck's ammunition problem: one flying body every upkeep, forever, for two mana.
Ulamog, the Ceaseless Hunger ↗
Exiles two permanents on arrival. The single best card to find off a Mass Polymorph.
Teferi's Protection ↗
Phases out your whole board, protecting a table's worth of conversions from one wipe.
Rhystic Study ↗
Cheap card flow to dilute the dead-draw problem, which is this deck's real weakness.
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 and safe when the wipe resolves, and they come back — bigger — at the end step.
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 exactly 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.
