Commander builds
Commander deck builds at three brackets
A full 100-card build for one commander at a time. Each is a core list plus two swap ladders, one that takes it down to a budget and one that takes it up to bracket 4.

Every build, newest set first
Builds are grouped by the set their commander comes from, newest release first. The line under each name gives the core list's bracket floor and whether the page was written before the set came out, which matters for how far to trust its prices.
Darkhold Destiny Commander (MDC)
-
Gargantos, the Endbringer
No bracket floor · Written before release His counters double on your upkeep and the damage he deals reaches everybody, so every slot in this list is spent on landing one hit rather than on fighting through three boards.
Marvel: Darkhold Destiny (MDD)
-
Magik, Illyana Rasputin // Darkchild, Demon Uncaged
Bracket 3 floor · Written before release Magik becomes Darkchild at the end of any turn in which you sacrificed two permanents, and cracking a Treasure or a fetchland counts. That makes the flip a question about the mana base, so this build answers it with lands and Treasure and then makes every one of those sacrifices cost the table life.
Star Trek (TRK)
-
Captain Benjamin Sisko
Bracket 3 floor · Written before release Each spell or ability you choose modes for on your own turn pays out a 1/1 Officer at your end step, and the Officers set how big a spell Captain Benjamin Sisko's seven-mana ability can cast for free. This build is thirty-five cards that make you choose and a mana base that pays for all five colors at once. -
Captain James T. Kirk
Bracket 3 floor · Written before release Captain Kirk gets one mode while you hold a card and all three once you hold none. So this list plays its whole hand before he attacks, and takes its extra cards off the top of the library, where they never reach the hand at all. -
Captain Kathryn Janeway
Bracket 3 floor · Written before release Captain Kathryn Janeway makes every creature that enters show you the top card of your library, and this build is about choosing what is there when it does: lands go to your hand, creatures get cast straight off the top, and everything else turns into a +1/+1 counter. -
Cleveland Booker, Empath
Bracket 3 floor · Written before release Every land that enters with Cleveland Booker on the battlefield makes a 2/2 Worm that is not allowed to block, so this list gives an army with no defence a job on every turn, including the turns its newest Worms are too fresh to attack. -
Constable Odo
Bracket 3 floor · Written before release A creature held down by stun counters never leaves the battlefield, so if it is a commander its owner has no way to cast it again. Every flicker in this list hands Odo that choice once more: lock something down for two more turns, or take two Clues. -
Dal R'El, Augment Orphan
Bracket 3 floor · Written before release Dal R'El pays a mana for every land that arrives and a card for every land you are willing to lose, so this build plays lands that come down in pairs and the cards that bring the sacrificed ones back. -
Data, New Life
Bracket 3 floor · Written before release Data, New Life puts a +1/+1 counter on himself for every card you draw and does nothing else, so his power is a running count of your draws. This mono-blue list draws in small, cheap pieces through the whole round and wins with commander damage. -
Dr. Beverly Crusher
Bracket 3 floor · Written before release Dr. Crusher doubles what your permanents do when you gain life and leaves the life itself alone. So this list is built only from cards that say “whenever you gain life”, and the end-step lifegain cards most white decks lean on stay in the binder. -
Georgiou, Terran Emperor
Bracket 3 floor · Written before release Georgiou lets you play on at zero life or less, and every one of your end steps that finishes there brings ten Officer tokens. This build spends your life to get there early, then keeps her on the battlefield, because losing her down there loses the game. -
Gowron, Eager for Battle
No bracket floor · Written before release Gowron sacrifices a creature for free whenever you like, grows from every death at the table, and draws a card only when the creature he eats is a Klingon. Klingons did not exist in Magic before this set, so most of the work here goes into manufacturing them. -
Kira Nerys, Firebrand
Bracket 3 floor · Written before release Kira Nerys turns any creature that enters during your combat into an attacker, and one that enters after blockers are chosen has no blocker. So this build makes its creatures at instant speed and waits for the blocks. -
Lieutenant Commander Data
Bracket 3 floor · Written before release Lieutenant Commander Data takes a +1/+1 counter whenever anyone at the table casts a noncreature spell, and turns three counters and one mana into a card. This list is mostly cheap noncreature spells, so he grows on every turn and you choose each turn whether the counters become cards or commander damage. -
Quark, Humble Proprietor
Bracket 3 floor · Written before release Quark hands you a Treasure in every upkeep at the table and then forbids you to sacrifice it. A Treasure that can't be sacrificed is still an artifact you can tap and count, and the day Quark leaves the battlefield the whole pile is mana again. -
Scotty, Miracle Worker
Bracket 3 floor · Written before release During your main phase Scotty lets you cast any instant or sorcery in your graveyard for its mana cost, as long as you also return another creature you control to your hand. This list is built so the creature going back is one you wanted to cast again, and the spell coming back is one worth casting twice. -
Seven of Nine
Bracket 3 floor · Written before release Seven of Nine draws a card each time you choose a mode, and three modes chosen at once still count as one choice, so the cards worth most to her are the permanents that make you choose again every turn. -
Vash, Freelance Archaeologist
No bracket floor · Written before release Vash, Freelance Archaeologist draws once a turn off cards leaving your graveyard, and the turn does not have to be yours. Most of this list exists to pull something out of the yard while another player is taking their turn, three times every round.
Star Trek Commander (TRC)
-
Commander Spock
Bracket 3 floor · Written before release Commander Spock casts a spell for free when its mana value is no higher than the number of differently named lands you control. So this list is a mana base before it is anything else: thirty-eight lands, and no two of them share a name. -
Jean-Luc Picard, Luminary
Bracket 3 floor · Written before release Picard draws whenever an artifact, legend or Saga costing three or more lands on your side, and the second card you draw in any turn charges a Spacecraft. This list is built to find that second card on every player's turn, so its ships fill up without a creature tapping for them. -
Koloth, Tribble Hunter
Bracket 3 floor · Written before release At a table of four, six of the eight Tribbles Koloth makes each turn belong to your opponents, and every one of them has to attack somebody other than you. This build gets paid for the fights those six start, and turns its own two into cards and damage. -
Locutus of Borg
Bracket 3 floor · Written before release Locutus gives every artifact creature you control the same combat damage trigger, and the 1/1 it creates is an artifact creature too, so each token that connects can make another. The build is about getting small artifacts past blockers and letting the count compound. -
The Borg Queen
Bracket 3 floor · Written before release Every time she enters or attacks, she takes a creature off the top of an opponent's library and keeps it. So this list spends its slots on landing a seven drop early, then on making her enter and attack as many times as the game allows. -
Worf, Defiant Commander
Bracket 3 floor · Written before release Battlefront counts the opponents you attacked, not the creatures you attacked with. So this list is built to put one body in front of every player each turn, and to have the mana ready for whatever that turns over.
Mystery Booster Commander Edition (MBC)
-
Ashaya's Enduring Bond
Bracket 3 floor · Written before release Thirty legendary sorceries have been printed and exactly one of them says it can be your commander. The line I would take with it is to stop reading commander tax as a penalty, because on this card it is the only dial that makes the spell bigger. -
Blor the Impervious
No bracket floor · Written before release Five mana buys a 3/3 with trample, hexproof and indestructible, and that is the whole card. Most voltron commanders spend a third of the deck insuring the creature, so the interesting question here is what the freed slots buy, and which answers are still live. -
Chief Magistrate of Mercadia
No bracket floor · Written before release Chief Magistrate of Mercadia copies every creature token you already control, once per upkeep, for as long as the crown stays on your head. So the ninety-nine behind it are not really a token deck. They are a deck about surviving one turn cycle at a time. -
Elda, Conjurer of Spectacle
Bracket 3 floor · Written before release Elda, Conjurer of Spectacle copies the first creature you cast each turn and hands an identical copy to an opponent you choose. These ninety-nine cards exist to make that an uneven trade rather than a fair one. -
Grizzlegom, Hurloon Hero
Bracket 3 floor · Written before release Rulebreaker hands you every land in Magic. This build gives most of them back, because a red green land carrying three printed types is worth more to Grizzlegom than an off color land carrying one. -
Homer, the Hermit
Bracket 3 floor · Written before release Homer reads like a crab tribal card and builds like a land deck. The crabs set the number, and the lands are what multiply it. -
Olag and Miau, New Friends
Bracket 3 floor · Written before release The counters on the first two lines are not how this deck wins. The third line is, it counts tapped bodies rather than power, and a Vehicle taps a board faster and more safely than an attack does. -
The Madcap Jester
Bracket 3 floor · Written before release The Madcap Jester does not steal a card. It opens a window over three libraries that stays open past your next untap step, and these ninety-nine cards exist to leave you with mana inside it. -
Tsagan, Raider Warlord
No bracket floor · Written before release Tsagan counts how many of your creatures have first strike, then gives that number to every creature you control as raw power. Almost every card behind him is chosen to make the count bigger than one, and the best one for that job costs fifty cents. -
Zagorka, Mother of Sanctum
No bracket floor · Written before release Zagorka hands a free land to everybody at the table every single turn, including the three people trying to kill you. Take the trigger anyway. You are the only player collecting a landfall trigger for it.
Reality Fracture (FRA)
-
Aerid Konstrari
Bracket 3 floor · Revisited after release, 5 October 2026 Aerid Konstrari counts artifacts rather than creatures, which turns a Signet into a threat and makes the boring half of a Gruul deck the half that ends the game. -
Denzilore Fatehold
Bracket 3 floor · Revisited after release, 6 October 2026 Denzilore Fatehold pays you for saying a word, not for playing a card. The line I'd take is ninety-nine slots arranged to say that word as many separate times as a turn allows. -
Hapatra, the Desert Fang
No bracket floor · Revisited after release, 5 October 2026 Hapatra reads your graveyard for a number and hands it to every opponent at once, so the deckbuilding question is not what she kills. It is how big that number is and what the card holding it did for you on the way down. -
Ingris Stingerquill
Bracket 3 floor · Revisited after release, 5 October 2026 Every creature you attack with pings all three opponents for one, whatever its power. So this build spends its ninety-nine slots on bodies, and on the handful of effects that turn that 1 into a 4. -
Kwia Vigorbloom
Bracket 3 floor · Revisited after release, 6 October 2026 Kwia makes one Lotus a turn however much life you gain, so the build that gets the most out of her is not the one that gains the most life. It is the one that gains a little on all four turns of the cycle. -
Uldaros Theorix
Bracket 3 floor · Revisited after release, 6 October 2026 Uldaros reads like a reward for burying something enormous. The six is a shared budget rather than a size limit, so the build that gets the most out of him is stocked with the cheapest cards in the format, and the best of them costs one mana and puts an eight-drop onto the battlefield. -
Vraska, Soul of Stone
Bracket 3 floor · Revisited after release, 6 October 2026 Vraska turns every noncreature spell into a Treasure that is also a creature, and hands it vigilance. The creature half is what makes the token interesting, and it is also what taxes it, so most of these ninety-nine cards are here to pay that tax.
Reality Fracture Commander (FRC)
-
Jace, Multiverse Architect
Bracket 3 floor · Revisited after release, 5 October 2026 The minus three is a Polymorph, and Polymorph decks get better the fewer creatures they run. This one runs three. -
Nissa, Leyline Tamer
Bracket 3 floor · Revisited after release, 6 October 2026 Every other card in Magic with Nissa in its name has green somewhere in its colour identity. This one costs, so building her means working out how much of a landfall deck is left once you take away the colour that invented the mechanic.
-
Tamiyo, Upriser Crowned
Bracket 3 floor · Revisited after release, 6 October 2026 Every other monarch commander pays to keep the crown. This one charges rent when it is taken, so the build spends those slots on attacking instead. -
The Ur-Sphinx
Bracket 3 floor · Revisited after release, 6 October 2026 Nine mana buys a 10/10 that mills the whole table and casts what it finds, and the half of this card you will lean on costs nothing at all.
The Hobbit (HOB)
-
Bard, King of Dale
Bracket 3 floor · Written after release Bard turns every card you draw into two, except the first card of your draw step, and every token you create into two tokens. This list is built from the cards that use both lines at once: Clues that become cards, and draws that become tokens. -
Beorn the Fierce
No bracket floor · Written after release Beorn the Fierce makes one of your creatures a Bear at every combat, and nothing on the card ever turns it back. This build treats the Bear count as a number that only climbs, and spends each trigger on the creature most worth adding to it. -
Radagast of Rhosgobel
Bracket 3 floor · Written after release Radagast of Rhosgobel takes two mana off the first creature spell you cast each turn and lets you cast it at instant speed, and the card never says whose turn. So this build passes with its mana open and spends it while the other players are taking theirs. -
The Great Goblin
Bracket 3 floor · Written after release The Great Goblin deals 2 damage each time a Goblin, Orc or Army of yours gets counters, and one counter does exactly as much as ten. So this build counts creatures rather than counters, and fills its slots with cards that put counters on several of them at once. -
Thranduil, the Elvenking
Bracket 3 floor · Written after release Thranduil, the Elvenking has every activated ability of every Elf card in your graveyard, so each Elf in this build gets cast once and then used again on a 5/6. This is the Elf deck that keeps feeding that graveyard, with the infinite loop most Thranduil lists chase held back for the top rung.
The Hobbit Eternal (HOC)
-
Gandalf, Party Guest
Bracket 3 floor · Written after release Every legendary Wizard you control lets Gandalf, Party Guest cast a bigger spell for free when your combat begins, two more mana value each, and he counts himself. So this list brings twenty three more of them, four other Gandalfs among the guests, and spells big enough to be worth the wait. -
Smaug the Impenetrable
No bracket floor · Written after release Smaug the Impenetrable makes a Treasure for every point of noncombat damage he is dealt, and indestructible means none of that damage can kill him. So this build aims its sweepers and its burn at its own commander, and spends what comes back. -
Thorin, King of Durin's Folk
Bracket 3 floor · Written after release Thorin counts artifact tokens, so every Treasure he hands you is +1/+0 on each of your other Dwarves until the day you crack it. This build pays for its spells with lands and rocks and lets the pile grow.
Marvel Super Heroes (MSH)
-
Bruce Banner // The Incredible Hulk
Bracket 3 floor · Written after release The Incredible Hulk untaps and attacks again every time he is damaged mid-combat, so this build fills its slots with instants aimed at your own commander, and the smallest of those hits cost him nothing at all. -
Nick Fury, Agent of S.H.I.E.L.D.
Bracket 3 floor · Written after release Nick powers up once each time he enters the battlefield, so this build sends him away and brings him back eight different ways, and every return is another look at seven cards for a Hero, Equipment or Vehicle to put straight into play. -
Thanos, the Mad Titan
Bracket 3 floor · Written after release His power-up destroys every other creature with an odd mana value, or every one with an even mana value, and you choose which as it resolves. Every creature in this list costs an even amount, so odd always spares your side, and each time Thanos comes back to the battlefield the next wipe costs three mana. -
The Astonishing Ant-Man
Bracket 3 floor · Written after release The Astonishing Ant-Man keeps a +1/+1 counter for every card you draw, and three mana turns any number of them into 1/1 Insects. So this list draws on every player's turn, saves the counters up, and spends them at instant speed, ideally in answer to the removal spell aimed at him. -
Tony Stark // The Invincible Iron Man
Bracket 3 floor · Written after release The front face finds an artifact and the back face puts one onto the battlefield for nothing every combat, so this list runs forty artifacts and saves its six to nine drops for Iron Man instead of casting them. -
Ultron, Artificial Malevolence
No bracket floor · Written after release Ultron, Artificial Malevolence copies any nontoken artifact that enters under your control for two more mana, and the copy of a mana rock arrives as a creature that cannot tap until your next turn. This colorless list is built so every copy pays its two mana back, most of them on the turn they arrive.
Secrets of Strixhaven (SOS)
-
Blech, Loafing Pest
No bracket floor · Written after release Blech puts a counter on every Pest, Bat, Insect, Snake and Spider you control each time you gain life, whatever the amount. This list fills the deck with those five types and with ways to gain life a point at a time, and fourteen of its creatures do both. -
Lorehold, the Historian
Bracket 3 floor · Written after release Lorehold, the Historian makes any instant or sorcery cost two mana when it is the first card you draw in a turn, and its loot gives you that draw in every opponent's upkeep. So this build runs the most expensive spells red and white have, and spends its other slots choosing which one is on top. -
Prismari, the Inspiration
Bracket 3 floor · Written after release Prismari, the Inspiration copies each instant and sorcery you cast once for every spell cast before it that turn, your opponents' spells included. So this build casts on their turns, and the copies arrive a few at a time instead of in one long turn of yours. -
Quandrix, the Proof
Bracket 3 floor · Written after release Cascade only ever finds a card that costs less than the spell it came from. So this build keeps its instants and sorceries at three mana and up wherever it can, and puts the cheap half of the deck in creatures, mana and enchantments for those spells to find. -
Silverquill, the Disputant
Bracket 3 floor · Written after release Every instant and sorcery you cast can eat a creature and come back as two spells. This build plays that as casual aristocrats, where the creature you feed Silverquill drains the table on its way out and the copy is the bonus. -
Witherbloom, the Balancer
Bracket 3 floor · Written after release Witherbloom, the Balancer takes one mana off every instant and sorcery for each creature you control, and only ever generic mana. So this build puts bodies down first, then casts the Golgari spells whose cost is mostly generic, and with seven creatures out the nine mana In Garruk's Wake costs two black.
Teenage Mutant Ninja Turtles (TMT)
-
Dark Leo & Shredder
Bracket 3 floor · Written after release Dark Leo & Shredder halve the life of any player they deal combat damage to once you control five Ninjas, and their sneak cost puts them into combat after blockers are chosen. This build sends them back to your hand after each hit, because cast from there the sneak is two mana every time and the commander tax never applies. -
Raph & Mikey, Troublemakers
No bracket floor · Written after release Raph & Mikey put the first creature card off the top of your library into every attack they make. This build fills the ninety-nine with creatures that do their work the moment they land, because a creature that arrives that way never gets to use an attack trigger. -
Rat King, Verminister
Bracket 3 floor · Written after release Rat King, Verminister returns every card in your graveyard that shares a name with the one he targets, and only two Rats in Magic may appear in a Commander deck more than once. This build plays fifteen copies of the better of them, Rat Colony, so one activation brings back the whole pile, the three Colonies sacrificed to pay for it included. -
Splinter, Radical Rat
Bracket 3 floor · Written after release Splinter makes each triggered ability of a Ninja creature you control trigger twice, and for two mana he lets one Ninja through unblocked. So this build picks each Ninja for what its trigger does the second time, and leaves the 2/4 rat at home holding that mana up. -
Super Shredder
Bracket 3 floor · Written after release Super Shredder takes a +1/+1 counter whenever another permanent leaves the battlefield, on any side of the table and of any card type. So this build treats a cracked fetchland, a spent Treasure and an opponent’s sacrificed creature as the same thing, a pump spell, and spends its protection on keeping the counters once they land.
Lorwyn Eclipsed (ECL)
-
Ashling, Rekindled // Ashling, Rimebound
Bracket 3 floor · Written after release Each turn, Ashling, Rimebound adds two mana at the start of your first main phase that only a spell of mana value 4 or more can spend. Thirty eight of the sixty five spells here can spend it, and they are cast before combat, because that is when the mana runs out. -
Brigid, Clachan's Heart // Brigid, Doun's Mind
Bracket 3 floor · Written after release Brigid, Doun's Mind taps for one mana per other creature you control, and she can pay the white mana that flips her back out of that same tap. So she makes mana on every turn and a Kithkin on every second one, and this list treats every creature it casts as ramp. -
Doran, Besieged by Time
Bracket 3 floor · Written after release Doran, Besieged by Time never lets a wall deal damage with its toughness. It does something odder: every creature you attack with grows until its power matches the toughness it started with, so this build counts toughness as power and treats +0/+5 as a pump. -
Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight
Bracket 3 floor · Written after release Eirdu makes your creatures pay for the next one, Isilu brings each of them back once, and you pick a face at the start of every turn. This build is 38 creature cards, because a token can tap for convoke but Isilu never returns one. -
Grub, Storied Matriarch // Grub, Notorious Auntie
Bracket 3 floor · Written after release Each attack from Grub's back face copies one of your creatures and puts a -1/-1 counter on the original, and the front face hands a Goblin card back from your graveyard. This build is made of Goblins that leave something behind when that counter kills them, so the card an attack costs you is the card the next flip returns. -
High Perfect Morcant
No bracket floor · Written after release High Perfect Morcant makes every opponent put a -1/-1 counter on a creature of their choosing each time an Elf of yours enters, and lets any three Elves proliferate. So this build is about Elves that arrive in groups, and about the few cards that pay you for a counter somebody else placed. -
Maralen, Fae Ascendant
Bracket 3 floor · Written after release Maralen, Fae Ascendant can cast a free spell out of an opponent's library once on every turn, theirs as well as yours. This build is the flash Elf and Faerie deck that puts an Elf or Faerie onto the battlefield on each of those turns.
Avatar: The Last Airbender (TLA)
-
Avatar Aang // Aang, Master of Elements
Bracket 3 floor · Written after release Aang transforms once you have waterbent, earthbent, firebent and airbent in the same turn, and he does the firebending himself every time he attacks. This build spends its slots on the other three and runs all thirteen cards in Commander that airbend, because air is the element you run short of. -
Bumi, Unleashed
No bracket floor · Written after release Bumi, Unleashed untaps every land you control each time his damage reaches a player, then adds a combat that only land creatures may join. This build spends its mana before the first attack, because the hit pays it back, and puts that mana into lands that can fight. -
Iroh, Tea Master
Bracket 3 floor · Written after release Iroh, Tea Master gives an opponent one of your permanents as each of your combats begins, and the Ally he makes in return grows with every gift still on the other side of the table. So this list is built around what to give away, and to whom. -
Katara, the Fearless
Bracket 3 floor · Written after release Katara, the Fearless makes each triggered ability on your Allies fire twice and has none of her own, so this list is chosen one trigger at a time. Thirty of its thirty three Allies have something for her to double. -
Ozai, the Phoenix King
Bracket 3 floor · Written after release With Ozai on the battlefield, mana you leave unspent turns red and stays in your pool. So this build taps out every turn, keeps six floating to give him flying and indestructible, and spends the rest on extra combats his own firebending pays for. -
Sokka, Tenacious Tactician
Bracket 3 floor · Written after release Every noncreature spell you cast becomes a 1/1 Ally with menace and prowess, so this list runs fifty eight spells and only seven creatures, each picked to pay off a spell being cast or an Ally arriving. -
Toph, Hardheaded Teacher
Bracket 3 floor · Written after release Every spell you cast with Toph out wakes one of your lands as a hasty creature that comes back when it dies, so this list runs thirty three spells at two mana or less and treats its thirty five lands as the army.
What a build page gives you
Each page starts from one question, what this commander is asking the other ninety-nine cards to do, and argues every section from the list's own numbers: its land count, its curve, its colour sources and its bracket floor. Those are computed from the decklist by the same code behind the bracket checker and the mana base calculator, not typed in, so the figure in a sentence and the figure in the table beside it agree.
The two ladders are tables of cuts and adds. The budget ladder swaps the expensive cards for cheaper ones, and the bracket 4 ladder brings in the Game Changers and faster pieces the core list leaves out. Every rung is a complete 100-card deck with its own total, its own bracket floor and the date its prices were taken.
Every card is priced at its cheapest paper printing, because a build is a shopping list for a deck you don't own yet. Gold-bordered World Championship cards and oversized cards are left out of that search, since neither is legal to play. Any list loads into the deck builder with one button, or copies out as plain text with another.
Written before release, then checked after
Most of these builds are written while a set is still being previewed, before anyone has played the commander and while there is little data on it anywhere else. That timing has three costs, and each page states them where they apply: a card from the new set reads as not legal until release day, preorder prices run high and usually fall after release, and a bracket floor computed before release can move, because the Game Changers list is revised at bracket updates rather than with each set.
So every build written before release gets a second pass after it. Prices are taken again from the market, cards revealed after the page went up are considered, the bracket floor is checked against the current Game Changers list, and the FAQ is rewritten for the questions people ask once they are playing the deck. A row above that says “Revisited after release” has had that pass. A build written after its set came out doesn't need one.
FAQ
Which commanders get a full build here?
Mostly new legends, written while their set is still being previewed and there is little else published about them. A commander that is already out gets a build when there is a case to make for it that the usual lists miss, and the bracket ladder is always part of that case.
Why does a build cost less than adding up each card's usual listing?
Because each card is priced at its cheapest paper printing rather than at whichever printing a search for its name shows first, which is often a premium or a promo. For a deck you are buying into, the cheapest copy you can legally play is the number that matters. Hovering a card name on a build page shows that same printing, so the card and its price always describe one physical card.
Is the bracket shown for a build final?
It is a floor, computed from what the list contains, mainly its Game Changers and any mass land denial or extra turns. Your pod can always judge a deck as stronger than its floor. On a build written before its set released, the floor is also provisional, because Wizards revises the Game Changers list at bracket updates rather than with each set.
Can I take a build into Moxfield or my own account?
Yes. Every build page has a button that loads the list into this site's deck builder, ready to edit and save to a free account, and one that copies it as plain text that Moxfield, Archidekt and Arena all import.
