Stax is the umbrella term for decks that attack resources instead of life totals: taxing spells, denying untap steps, forcing sacrifices, and shutting off abilities until nobody can play Magic except the person who built for it. It isn't one effect, it's about eleven of them, and this page walks through each with the cards that define it.
A stax deck attacks what opponents are allowed to do, rather than how much life they have. Every card
on this page takes away a resource: mana, untap steps, cards, permanents, abilities, or the attack itself.
"Stax" is player slang, not a term in the Comprehensive Rules. It comes from a Vintage deck built around
Smokestack, Tangle Wire and Crucible of Worlds, and over time the name detached from that specific list and
became the label for the whole idea: win by shrinking the game rather than by racing inside it. You'll hear
the same strategy called prison, resource denial, or "hatebears" when it's built on cheap creatures, and those
are dialects of one archetype, not separate ones.
The distinction worth holding onto is stax versus control. A control deck
answers threats after they appear, one at a time, with counterspells and removal. It is reactive and it
spends a card per threat. A stax deck changes the rules up front with permanents, so the threats never get
cast. That's why stax cards are almost always permanents and almost always symmetrical, and it's why a stax
deck's opening turns look like it's doing nothing: the payoff is everything that doesn't happen
afterwards. Read Control: The Commander Archetype → for
the other half of that pair.
MYTH
Stax means land destruction and making people miserable.
FACT
Land destruction is one of eleven categories, and it's the most contentious one. Ghostly Prison, Rest in Peace and Torpor Orb are all stax effects, and all three show up in ordinary casual decks that nobody thinks of as stax at all.
Breaking parity: the one idea that makes stax work
Almost every stax card is symmetrical. A symmetrical lock helps nobody, so the entire skill of the archetype
is being the player who minds least.
Sphere of Resistance taxes you the same {1} it taxes everyone else. Smokestack makes you sacrifice too.
Winter Orb stops your lands untapping as well. None of that is a drawback if your deck was built so the
constraint costs you less than it costs the other three players, and there are five reliable ways to arrange
that:
1. Be cheaper. A tax is a percentage, not a number. A {1} surcharge on a deck
whose average card costs two mana is a 50% tax; on a deck averaging four it's 25%. Stax lists run low curves
for the same reason a
good mana curve → matters generally, just
more so.
2. Own fewer permanents. Smokestack, Pox and every edict effect scale with what
you have on the battlefield. A deck holding four permanents outlasts three decks holding twelve, so "do less"
is literally the plan.
3. Use mana the lock doesn't touch. Winter Orb's text says
lands, so mana rocks untap normally underneath it. A stax deck that ramps on artifacts keeps most of
its mana while the table keeps one land, which is exactly why the pairing has survived for thirty years. See
Mana Rocks: The Complete Guide →.
4. Untap outside the untap step. Seedborn Muse untaps your permanents during
every other player's untap step; Derevi, Empyrial Tactician untaps a permanent whenever a creature deals
combat damage to a player. Both make untap denial fully one-sided, and both are why those two cards read as
innocuous and play as oppressive.
5. Empty your hand on purpose. Ensnaring Bridge and Necrogen Mists cost nothing
to a deck that has already deployed everything it drew. The stax deck's hand is empty by design, so the cards
that punish a full hand are one-sided in its favor.
The eleven types of stax
Every stax card takes away a specific resource, and which resource it is determines who it hurts, how it gets
answered, and how the table reacts to it. Here's the whole taxonomy in one table, then each category in turn
with the cards that define it.
TypeWhat it deniesSignature card

Zone & search denialGraveyards, libraries, tutorsRest in Peace
Combat denialThe ability to attack (usually you)Ghostly Prison
Punisher taxesNothing: it just charges them for itManabarbs
No real deck picks one row. A functioning stax list combines three or four categories so the pieces cover each
other's gaps: a tax effect slows the table down, an untap effect stops them catching up, and a spell
restriction stops the one card that would have answered both.
1
Taxation: everything costs more
The gentlest category and the most widely played. Nothing is forbidden; it just costs more mana than the table can spare.
Taxation is where most stax decks start, because a cost increase is a soft effect that scales into a hard one.
One Sphere of Resistance is an inconvenience. A Sphere plus a Thalia plus a Grand Arbiter is a table where a
four-mana card costs seven, and at four players nobody has seven. The category also includes the format's
cheapest disruption. Thorn of Amethyst, Vryn Wingmare and Lodestone Golem all do variations of the same job.
Because taxes are symmetrical, they're the category most dependent on the curve discipline described above.
A stax deck running Sphere of Resistance and a five-mana commander has taxed itself into the same corner as
everyone else.
2
Untap denial: the resource is your untap step
Mana isn't a pile you own, it's a thing you get back once per turn. Take away the untap step and mana becomes a one-time resource.
This is the most recognizable form of stax and the one people mean when they picture the archetype. It's
also the most brutal, because it doesn't take anything away. It just stops giving it back. Everything the
table taps stays tapped, so the game slows to whatever pace the denial permits, which is usually about one
spell every two turns. See The Phases of a Turn → for
why the untap step is the step with no priority and no way to respond.
Tangle Wire belongs to this family too, from the other direction: instead of preventing untapping, it forces
each player to tap permanents down on their own upkeep for four turns and then fades away. That expiry is the
point: it buys the stax deck the turns it needs and expires before it becomes the stax deck's problem.
3
Tempo taxes: everything enters tapped
A turn of delay on every permanent an opponent plays, charged one card at a time and almost never contested.
These read as the mildest cards on the page and do far more than they look like they do. A land entering
tapped costs a full turn of mana. A creature entering tapped can't block this turn cycle and can't be a
surprise blocker at all, which turns off haste, ambush blockers and half the removal-dodging tricks in the
format at the same time. In a deck that wants to attack, they're stax pieces that also enable the clock.
Root Maze, Frozen Aether and Loxodon Gatekeeper cover the same ground with different splits between artifacts,
creatures and lands. Pick by what your pod's decks actually rely on. Against a heavy nonbasic manabase, the
land half is worth more than the creature half.
4
Mana denial: attacking lands and rocks directly
The most effective category and the most socially fraught. Everything else on this page taxes mana; this attacks the mana base itself.
Commander manabases are greedy (four and five colors, dozens of nonbasics, a fetchland package) because
the format's other conventions assume nobody is attacking them. That assumption is exactly what these cards
punish. Blood Moon and Back to Basics don't destroy anything; they simply make a carefully-tuned manabase stop
producing the colors it was built for. Read
The Land & Mana Base Guide → for why a
Commander manabase is so exposed to this in the first place.
The category also includes repeatable land destruction: Strip Mine or Wasteland recurred every turn with
Crucible of Worlds is a soft lock all by itself, and the artifact-mana shutoffs Null Rod, Stony Silence and
Collector Ouphe. Contamination goes furthest of all, restricting every player to one black mana a turn.
This is the one category to raise before the game starts. Wizards' bracket
guidelines ask players to keep mass land denial out of brackets 1 through 3 entirely. It's only unrestricted
at Optimized and cEDH. That isn't a ban, it's a shared expectation, and breaking it without a heads-up is the
fastest way to end a Commander night early. See
The Commander Bracket System →.
5
Spell restrictions: how many, which, and from where
Rather than pricing spells, this category caps them: one per turn, none from the graveyard, or none at a chosen mana value.
These are the hardest counters to combo in the format. A storm turn, a cascade chain, or an infinite loop that
needs to cast three cards doesn't get slower under Rule of Law. It stops existing. That makes this category
the reason stax and combo are natural enemies at high power, and the reason cEDH stax lists are built around
it.
Arcane Laboratory, Eidolon of Rhetoric and Deafening Silence are near-copies of Rule of Law across other card
types and colors. Teferi, Time Raveler restricts opponents to sorcery speed, which shuts off instant-speed
interaction and flash combos. And the surgical versions (Sanctum Prelate, Gaddock Teeg, Meddling Mage,
Nevermore) name one thing and forbid it, which is what you want when the table has one card that beats you.
6
Forced sacrifice: the Smokestack family
Everything above stops opponents deploying. This category takes back what they already deployed, every single turn.
Sacrifice effects sidestep protection: no hexproof, ward, indestructible or regeneration stops "sacrifice a
permanent," because the controller is the one doing it. That makes them the answer to the boards that removal
can't touch, and repeatable sacrifice is the closest thing the archetype has to an inevitability engine.
Smokestack rewards the low permanent count described earlier, and it's the clearest example of stax as a
resource race: you build a board of four cheap permanents, they build a board of twelve, and then the counter
goes up every turn until only one player still has anything. Pair it with a token generator and the parity
breaks entirely. You sacrifice a token every upkeep and they sacrifice real cards.
7
Hand and draw denial: the other resource
Mana denial slows what opponents can cast. Card denial changes what they have to cast in the first place.
This category splits in two. Discard effects empty hands that are already full; draw restriction stops them
refilling. The second half matters more in Commander than anywhere else, because the format's whole engine is
card advantage. A deck denied its draw step engines is playing off the top of its library with 40 life it
can't use.
Spirit of the Labyrinth and Notion Thief cover the same draw-denial ground as Narset, and Hullbreacher did it
hard enough to get banned outright. It turned every opponent's card draw into treasure for its controller.
Painful Quandary sits on the boundary with the punisher category below, since it lets the spell resolve and
charges for it afterwards.
8
Ability shutdown: turning off the text box
A category of one-card answers. Each of these blanks a mechanic rather than a card, which is why they hit several decks at the table at once.
Commander decks are built on abilities far more than on spells: mana dorks, sacrifice outlets, equip costs,
enter-the-battlefield value, tap abilities on commanders. Shutting off a whole class of ability is the highest
card-for-card return in the archetype, and it's often not even read as stax when it happens. A Torpor Orb
just looks like a weird artifact until you realize four decks stopped working. See
ETB vs. Triggered vs. Activated Abilities →
for exactly which of these cards catches which.
Elesh Norn, Mother of Machines is the modern top end here. It doubles your enter-the-battlefield triggers and
turns off everyone else's, so it's a lock piece and an engine on one card. Hushbringer stops both enter and
die triggers on a two-mana flier, and Pithing Needle names a single problem permanent when you only need one
thing switched off.
9
Zone and search denial: graveyards, libraries, tutors
Cards in Commander come from more than the hand. This category closes the other doors.
Graveyard hate is the most-played stax effect in the format by a wide margin, and most people playing it
don't think of themselves as stax players at all. Search denial is rarer and more pointed: tutors are how the
rest of the table finds the answer to your lock, so a Stranglehold is often the piece that converts a strong
board into an unbeatable one.
Leyline of the Void and Ashiok, Dream Render handle graveyards from other angles, Mindlock Orb stops all
library searching for everyone, and Aven Mindcensor cuts a tutor down to the top four cards at instant speed,
which is the version you cast in response to the tutor rather than before it. Drannith Magistrate, from the
spell-restriction category above, is the widest zone-denial card in the format.
If you're building around the graveyard yourself, this category is what your deck has to survive. See
Graveyard Recursion →.
10
Combat denial: pillowfort
The defensive subset. These don't limit what opponents can do, only who they can do it to.
Pillowfort is stax pointed inward. Ghostly Prison doesn't slow anybody's development, cost them a card, or
stop them casting anything; it just makes you the least attractive player to attack. That's a meaningful
distinction socially as well as mechanically: a pillowfort deck redirects the game, while a resource-denial
deck stops it. Most tables that dislike stax are perfectly happy with pillowfort.
Propaganda and Windborn Muse are the blue and white-creature versions of Ghostly Prison; Sphere of Safety
scales the tax with your enchantment count, which makes it the
Enchantress → deck's version. Note that
Ensnaring Bridge and Silent Arbiter are genuinely symmetrical: they flatten the whole table's combat step, not
just yours, which is the line where pillowfort turns back into real stax.
11
Punisher taxes: charging instead of preventing
The weakest category, and the one with the clearest failure mode: a player who can afford the price just pays it.
Punisher effects permit everything and charge for it in life or cards. Against a slow, mana-hungry table
Manabarbs is a genuine clock; against a deck with a Sol Ring and 40 life it's a tax that gets paid without
comment. What makes them worth knowing is the combination: a punisher card next to a real lock stops opponents
buying their way out, and the ones that charge mana rather than life (The Tabernacle at Pendrell Vale above
all) hold up as locks in their own right.
Once several pieces are down, the position has a name. A soft lock leaves
opponents able to act, just badly. One land untapping a turn under Winter Orb is still one land. A
hard lock means they cannot take any meaningful action at all and no draw will
change that: Stasis with a way to pay for it forever, or Smokestack with more counters than anyone has
permanents.
The distinction is worth naming because it's the difference between a slow game and a stopped one. A soft
lock is a legitimate, interesting board state that opponents can still play through. A hard lock with no
clock attached is the thing that turns Commander night into forty minutes of nobody doing anything, and the
convention at most tables is simple: if you've established a hard lock, you should be winning within a turn
or two, or you should say so and let the table decide whether to keep playing.
A soft lock coming together, turn by turn
1
Turn two, you resolve Winter Orb. From now on, everyone untaps one land per turn, including you.
2
Turn three you play a land and cast Sol Ring and a Signet. Winter Orb only stops lands from untapping, so your rocks untap every turn and theirs would too, if they'd played any.
3
Turn four you cast Smokestack off the rocks and pass. You control four permanents; the table controls fifteen between them.
4
Turn five you add the first soot counter. Everyone sacrifices one permanent per upkeep, and they can only redeploy one land's worth of mana a turn.
5
Turn seven the counters are at three. Boards are empty, hands are stuck, and the game is decided, but nobody has actually lost yet, which is the part you have to plan for.
How stax decks actually win
Locking the table down isn't a win condition. It's the setup, and it's the part stax decks most often forget to finish.
Because the lock is the hard part, the kill is usually small: a single evasive creature swinging for two a
turn, a planeswalker ticking toward an ultimate nobody can pressure, or a two-card combo assembled behind a
wall of taxes that stop anyone answering it. In cEDH the last of those is standard. The stax package exists
to buy the turns the combo needs. In casual play the first is more common, and it's why stax games run long.
The practical deckbuilding note: a stax deck needs a faster clock than its designer thinks. Once the lock is
complete the game is decided and everything after that is bookkeeping, so the difference between a good stax
deck and an exhausting one is entirely how many turns it takes to convert a won position into a finished game.
A commander that attacks, or a wincon that doesn't need the board, is worth more here than one more tax piece.
Playing against stax
Stax decks lose to the same four mistakes not being made. Whatever you're piloting, these are the habits worth
building:
✕
Casting removal on the first target you see. Your Naturalize is worth more
held for the Smokestack than spent on a Signet. Against a stax deck, interaction is a resource to budget,
not to spend.
✕
Overextending into a board that punishes it. Committing six permanents
against an open Smokestack, or a full hand against Ensnaring Bridge, is doing the stax deck's job for it.
✕
Waiting to deploy mana. If a tax piece is coming, the mana rock you cast now
costs one less than the same rock cast after it lands. Develop into the threat, not after it.
✕
Playing it as a 1v1. Three players who agree on the threat beat one player
who has locked the board. Say what the stax deck is doing out loud. That's the mechanism multiplayer gives
you, and it works.
The card-level answer is broad, cheap, and preferably instant-speed. Most stax packages are artifacts and
enchantments, which is a narrow enough range that four slots covers it:
Stax is the archetype most likely to cause a genuinely bad evening, and pretending otherwise doesn't help
anyone. It reduces what other people get to do in a direct, visible way, and in a casual pod it often produces
long turns where three players do nothing. That doesn't make it wrong to play. It makes it something to raise
before the game starts rather than reveal on turn four.
The Rule 0 conversation → is exactly the tool for
this, and the honest version is one sentence: "this deck taxes and locks, and it includes mass land denial, so
is that a game you want tonight?" Brackets give the same conversation a shorter vocabulary; a dedicated stax
or lock package is bracket 4 territory, and mass land denial is explicitly not expected below it. One
objection at the table is enough. That's the norm, and it applies here more than anywhere.
Two things make a stax deck welcome rather than tolerated: a real clock, so the game ends once it's decided,
and a willingness to sleeve up something else when the pod says no. Both are easier if you know how your
pod's games actually go, which is what tracking them tells you.
Frequently Asked Questions
What is stax in MTG?
Stax is player slang for any strategy that attacks resources and actions instead of life totals: taxing spells, denying untap steps, forcing sacrifices, limiting how many spells can be cast, or shutting off abilities. It isn't a rules term. The name comes from a Vintage deck built around Smokestack, and it now covers every deck whose plan is to shrink what opponents are allowed to do.
What are the different types of stax?
Broadly eleven: taxation (spells cost more), untap denial (permanents don't untap), tempo taxes (everything enters tapped), mana denial (lands and rocks attacked directly), spell restrictions (one spell a turn, or none from certain zones), forced sacrifice, hand and draw denial, ability shutdown, zone and search denial (graveyards and tutors), combat denial or pillowfort, and punisher effects that charge life or cards rather than preventing anything. Most real stax decks combine three or four of these categories rather than committing to one.
What's the difference between stax and control?
Control answers specific threats after they appear, one at a time, with counterspells and removal. Stax changes the rules of the game up front with permanents, so the threats never get cast in the first place. The two overlap heavily (most stax decks run counterspells and most high-power control decks run a few tax pieces) but the distinction is reactive versus pre-emptive.
Is stax the same as prison or pillowfort?
They're overlapping terms. Prison usually means a stax deck built to lock the game out completely rather than tax it. Pillowfort is the defensive subset (Ghostly Prison, Propaganda, Crawlspace) that stops opponents attacking you without limiting anything else they do, so it's much gentler on the table than resource denial is.
Is stax banned in Commander?
The strategy isn't banned, and most of its cards are legal. A few specific effects are: Braids, Cabal Minion is banned for repeatable one-sided sacrifice from the command zone, and Hullbreacher is banned for turning opponents' card draw into your own. Beyond bans, Wizards' bracket guidelines ask players to keep mass land denial out of brackets 1 through 3, so an Armageddon deck belongs at bracket 4 or 5.
Is stax bad for casual Commander?
It's a poor fit for most casual pods without a conversation first. Stax deliberately reduces what everyone else gets to do, and a table that came to play its decks will not enjoy an evening of not playing them. That doesn't make it a bad archetype. It makes it one to raise in the Rule 0 conversation before shuffling up, and to pair with a real clock so the game actually ends.
How do you beat a stax deck?
Answer the lock piece rather than playing around it, and keep instant-speed artifact and enchantment removal in hand instead of casting it on the first target you see. Don't overextend into a Smokestack or a sweeper. Deploy your mana before the tax lands, not after. And say out loud what the stax player is doing. In multiplayer, three players who agree on the threat beat one player who has locked the board.
