MTG Modular Explained: All 24 Cards, the Rules and the Best Commander Deck

Modular is the mechanic that turns a dead artifact creature into a bigger one. A creature with modular arrives as a 0/0 wearing +1/+1 counters, and when it dies those counters move onto another artifact creature instead of disappearing. Nothing is wasted. That is the whole pitch, and it has held for twenty-two years across exactly 24 cards.

This guide covers every one of them: what modular does at the rules level, the wording quirk that lets a land have it, the only card in Magic with “Modular—Sunburst”, what the mechanic is legal in, what it costs, and a 100-card Zabaz, the Glimmerwasp Commander deck built around it. Every card fact here was pulled from the live Scryfall database on 10 September 2026, not from memory.

What modular actually does

Modular is two abilities wearing one keyword. The reminder text on Arcbound Worker spells both out:

Modular 1 (This creature enters with a +1/+1 counter on it. When it dies, you may put its +1/+1 counters on target artifact creature.)

Arcbound Worker, oracle text via Scryfall

The first half is a static replacement effect: the creature never exists on the battlefield without its counters. The second half is a triggered ability that fires on death and may move the counters — it is optional, it targets, and it moves all the counters currently on the creature, not just the ones modular put there.

That last detail is the entire reason the mechanic is good. Counters you add later ride along. Put three more +1/+1 counters on an Arcbound Worker with proliferate or a Steel Overseer activation, and all four counters transfer when it dies.

The rules text says “permanent”, the cards say “creature”

Comprehensive rule 702.43a defines modular in terms of permanents, not creatures: a permanent with Modular N enters with N +1/+1 counters, and when it is put into a graveyard from the battlefield you may move those counters to a target artifact creature. Every Arcbound card’s printed reminder text narrows that to “this creature”, because every Arcbound card is a creature.

One card is not, and it is the reason the distinction is worth knowing.

Modular creatures are 0/0 — which is a real liability

Of the 23 modular creatures, 21 are printed 0/0. They are alive only because of the counters. Remove the counters and the creature dies immediately as a state-based action, with no death trigger salvage worth speaking of — the counters that would have moved are gone.

This is why −1/−1 counter effects are so much better against modular than normal removal, and why the official rulings bother to address it. From the Arcbound Ravager rulings:

If this creature gets enough -1/-1 counters put on it to cause its toughness to be 0 or less (or the damage marked on it to be lethal), modular will put a number of +1/+1 counters on the target artifact creature equal to the number of +1/+1 counters on this creature before it left the battlefield.

Official ruling, 25 September 2006, via Scryfall

The two exceptions to the 0/0 rule are Arcbound Javelineer, printed 0/1, and Blaster, Combat DJ, printed 3/3 — the only modular creature in Magic with any printed power at all.

All 24 modular cards in Magic

Sorted by modular value, lowest first. Colour identity matters more than colour here, because it decides which Commander decks can run each card.

What the numbers look like

Nine cards at Modular 1, seven at Modular 2, and a long tail. 49 printed counters across the 23 cards with a fixed value — an average of 2.13 each, which is a deliberately modest number. Modular has never been a big-counter mechanic; it is a mechanic about counters that refuse to die.

Power Depot is the only modular card that is not a creature

Modern Horizons 2 printed an artifact land with Modular 1. It has no reminder text, because reminder text about a creature entering would be nonsense on a land. It enters tapped, taps for colourless or for any colour restricted to artifacts, and carries a +1/+1 counter that does absolutely nothing while it sits there being a land.

Then it goes to the graveyard, and the counter moves. The official ruling is unusually direct about it:

Yes, this land enters the battlefield with a +1/+1 counter, which does nothing while it’s a land. When it’s put into the graveyard from the battlefield, you may put its +1/+1 counters onto target artifact creature, no matter what Power Depot’s card types are at the time.

Official Power Depot ruling, 18 June 2021, via Scryfall

“No matter what Power Depot’s card types are at the time” is rule 702.43a’s word “permanent” doing its job. Crack a fetchland-style sacrifice, blow it up with your own Vandalblast, let it die to a land-destruction spell — the counter still lands on an artifact creature. In twenty-two years it is the only card that has ever done this.

Arcbound Wanderer is the only “Modular—Sunburst” card ever printed

Twenty-three modular cards print a number. Arcbound Wanderer, from Fifth Dawn, prints a keyword instead:

Modular—Sunburst (This creature enters with a +1/+1 counter on it for each color of mana spent to cast it. When it dies, you may put its +1/+1 counters on target artifact creature.)

Arcbound Wanderer, oracle text via Scryfall

Sunburst sets the number. Cast it off five colours of mana and it is a 5/5 that hands five counters to something else when it dies; cast it off a Wastes and it is a 0/0 that dies on arrival. The official ruling makes the mechanics explicit — the sunburst value only matters on the way in:

For the leaves-the-battlefield ability, the number of counters on Arcbound Wanderer at the time it left the battlefield is what’s relevant; the number of colors of mana used to pay its cost doesn’t matter anymore.

Official ruling, 1 December 2004, via Scryfall

There is a second ruling worth memorising before you build around it: you cannot split the counters. Modular targets one artifact creature. All the counters go to that one creature or none of them do.

Modular did not come from Mirrodin

Modular is the signature Mirrodin-block artifact mechanic and it appears on exactly zero cards in Mirrodin. It debuted in Darksteel on 6 February 2004, which contributed 11 of the 24 cards — the largest single set contribution the mechanic has ever received.

The shape of that table is the story of modular. Twelve cards in 2004, then fifteen years of nothing, then Modern Horizons brought it back one card at a time. Modern Horizons 2 alone printed eight, more than any set since Darksteel.

Zabaz debuted six weeks before his own set

Zabaz, the Glimmerwasp lists Modern Horizons 2 Promos with a release date of 6 May 2021, forty-three days before Modern Horizons 2 itself on 18 June. That is a genuine earlier printing rather than a same-day promo tie, so it is his real debut — and the kind of detail that a default-printing lookup silently gets wrong.

Modular is not a colourless mechanic

Everyone remembers modular as pure artifact colourless, because Darksteel’s eleven cards all were. Ten of the 24 have a colour identity.

This matters directly for deckbuilding. A colourless Commander deck can run only the 14 colourless cards. A Boros deck — red and white — can run 21 of the 24, everything except the black Arcbound Condor and the Gruul Blaster, Combat DJ. No other colour pair comes remotely close, which is most of the reason the deck at the bottom of this guide is Boros.

Blaster is the only card that gives modular to something else

Three modular cards mention the mechanic by name beyond their own reminder text, and all three are worth knowing:

• Arcbound Overseer — “At the beginning of your upkeep, put a +1/+1 counter on each creature you control with modular.” An eight-mana engine that grows your whole team every turn.
• Zabaz, the Glimmerwasp — if a modular trigger would put counters on a creature you control, it puts that many plus one instead.
• Blaster, Morale Booster — the back face of Blaster, Combat DJ. “Other nontoken artifact creatures and Vehicles you control have modular 1.”

Blaster is the outlier: it is the only card in Magic that hands modular to permanents that were not printed with it. It also carries the mechanic’s only Gruul colour identity, and it is the only modular card that is not Modern legal — the Transformers cards from 2022 were printed straight into Legacy, Vintage and Commander.

Nothing in Magic cares about modular unless it has modular

Search every paper card whose text contains the word “modular” but which does not have the keyword, and you get exactly one result: Modular Monstrosity, an Unstable card from 2017 that is not legal in any real format and merely has the word in its name. For comparison, running the same search shape on landfall returns three genuine outside references.

So in twenty-two years Wizards has printed no modular payoff that is not itself modular. If you want a card that rewards you for having modular creatures, your options are Arcbound Overseer, Zabaz and Blaster. That is the list.

Modular legality by format

Zero in Standard and zero in Pioneer, and those zeroes are structural rather than incidental. Pioneer begins at Return to Ravnica in 2012 — eight years after Darksteel — and every modular card printed since has arrived in a Modern Horizons set or a Universes Beyond product, none of which are Pioneer or Standard legal. Modular has never been a Standard mechanic in the modern era and, barring a straight reprint, never will be.

Pauper gets nine of the 24, read directly from each card’s Pauper legality rather than inferred from rarity — a card is Pauper legal if it has been printed at common in any set, which is not the same question as what rarity it is today.

What the whole mechanic costs

Here is where a normal card-price table would mislead you, so this one has two columns. The right-hand column is the cheapest printing of any kind. The left is the cheapest ordinary printing — excluding masterpieces, promos and boxed-set treatments that most players will never see in a binder.

Exactly one card diverges, and it moves the total by 82%. Arcbound Ravager‘s cheapest printing of any kind is a 2026 masterpiece at $2.48; its cheapest ordinary printing is the Modern Masters reprint at $19.84. Quote the first number and you have technically told the truth while giving a reader a completely wrong idea of what walking into a shop and asking for a Ravager costs.

On the ordinary basis, all 24 modular cards together come to $38.47, and Ravager alone is 51.6% of that. Twenty of the 24 cost under a dollar and total $6.50 between them. Prices are Scryfall’s USD figures on 10 September 2026 and will drift; check current numbers with our card pricing tool before you buy.

The best modular cards, ranked

1. Arcbound Ravager

A two-mana 1/1 that eats your own artifacts to grow, then hands the whole pile to the next artifact creature when it dies. It has been a defining Modern card for two decades and it is the only modular card anyone builds a competitive deck around. Sacrifice an artifact land, sacrifice a spent Ichor Wellspring, sacrifice Ravager itself in response to removal — the counters always end up somewhere.

2. Zabaz, the Glimmerwasp

One mana, legendary, and it upgrades every modular trigger you control by one counter. It also has “{R}: Destroy target artifact you control”, which reads like a drawback and is in fact a free sacrifice outlet that turns any artifact into value. Twenty-six cents.

3. Arcbound Overseer

Eight mana is a lot. An upkeep trigger that puts a counter on every modular creature you control is also a lot, and in a deck with a dozen Arcbound bodies it ends games. Two dollars.

4. Scrapyard Recombiner

Modular 2 on a three-mana body that taps and sacrifices an artifact to tutor a Construct card to hand. Half the Arcbound creatures are Constructs or fetchable targets; this is the closest thing modular has to a tutor.

5. Arcbound Shikari

The best of the Modern Horizons 2 batch. First strike, Modular 2, and an enters-the-battlefield trigger that puts a +1/+1 counter on every other artifact creature you control. In a wide board it is a one-card anthem that also leaves counters behind when it dies.

6. Arcbound Reclaimer

Remove a +1/+1 counter to put an artifact from your graveyard on top of your library. It converts modular counters into recursion, which is exactly the conversion an artifact deck wants, and the counters it spends still transfer if there are any left when it dies.

The Skullclamp interaction you should know about

A modular creature with exactly one +1/+1 counter is a 1/1. Equip Skullclamp — +1/−1 — and it becomes a 2/0, dies to state-based actions, draws you two cards, and moves its counter to another artifact creature. With Zabaz on the battlefield it moves two.

That is one mana to equip, two cards drawn, and a counter that ends up somewhere useful. Nine of the 24 modular cards have Modular 1, which is the exact configuration that turns Skullclamp into a repeatable draw engine rather than a liability. It is the single best reason to build the deck below in a format that allows it.

The best Commander deck for modular: Zabaz, the Glimmerwasp

Zabaz is a one-mana Boros commander who improves every modular trigger in the deck by one counter and doubles as a free sacrifice outlet. Boros is also the colour pair with the deepest legal access to the mechanic — 21 of the 24 cards.

The ruling that catches everyone

Zabaz the Glimmerwasp’s replacement effect requires it to be on the battlefield to work. Notably, that means it won’t increase the counters given by its own modular ability.

Official ruling, 18 June 2021, via Scryfall

Zabaz does not boost his own death trigger. He has to be alive when someone else’s modular trigger resolves. Build accordingly: he is an engine you protect, not a body you throw away.

How the deck wins

It is a counters-and-sacrifice deck, not an aggro deck. The modular package supplies bodies that always leave something behind, Zabaz taxes every one of those deaths upward, and the sacrifice outlets convert that into damage, cards or a lethal attack. 55 of the 100 cards are artifacts, which turns on Etched Champion‘s metalcraft, Foundry Inspector‘s cost reduction and Mystic Forge without any extra work.

The three sacrifice outlets do the heavy lifting: Blasting Station pings a player every time a creature dies and untaps whenever one enters, Altar of Dementia mills for the dying creature’s power (which, with a pile of transferred counters, is a real number), and Goblin Bombardment is free. Skullclamp turns the Modular 1 creatures into cards. If you want the deck to draw more, Tocasia’s Welcome rewards the small bodies you are already playing.

The decklist — 100 cards, $183.77

Thirty-three lands is low, deliberately: the curve is short, the artifact ramp is dense, and Power Depot counts as both. If the deck feels short on mana in practice, cut Arcbound Lancer at seven and Arcbound Overseer at eight for a Mountain and a Plains — they are the two cards that most often rot in hand.

Modular FAQ

What does modular mean in MTG?

Modular N means the permanent enters the battlefield with N +1/+1 counters on it, and when it dies you may move all of its +1/+1 counters onto a target artifact creature. It is comprehensive rule 702.43a.

Is modular a triggered or a static ability?

Both. The “enters with N counters” half is a static replacement effect; the “when it dies, move the counters” half is a triggered ability that uses the stack and targets.

Can I split modular counters between two creatures?

No. Modular targets a single artifact creature. All the counters go to one creature, or you decline the trigger entirely.

Do modular counters have to go to an artifact creature?

Yes. The target must be an artifact creature. A non-artifact creature is not a legal target, and if the only creature on the battlefield is a plain Bear the trigger simply does nothing.

Does modular move counters that were added later?

Yes. The trigger moves every +1/+1 counter on the permanent when it left the battlefield, regardless of where those counters came from. Proliferate, Steel Overseer activations and Arcbound Shikari’s enters trigger all ride along.

What happens if a modular creature is exiled instead of dying?

Nothing. The trigger only fires when the permanent is put into a graveyard from the battlefield. Exile, bounce to hand and shuffling into a library all shut modular off completely, which is why exile-based removal is the cleanest answer to these decks.

Why is my modular creature a 0/0?

Because that is its printed power and toughness — 21 of the 23 modular creatures are printed 0/0. The counters are the creature. Remove them and it dies as a state-based action.

How many modular cards are there in Magic?

Twenty-four, as of 10 September 2026. Twenty-three are artifact creatures and one, Power Depot, is an artifact land.

What set introduced modular?

Darksteel, on 6 February 2004. Mirrodin, despite being the artifact set everybody associates with the mechanic, has no modular cards at all.

Is modular legal in Standard?

No, and it has not been for two decades. It is legal in Modern (23 of 24 cards), Legacy, Vintage and Commander (all 24), and Pauper (9).

What is Modular—Sunburst?

A one-off on Arcbound Wanderer from Fifth Dawn. Sunburst supplies the number for modular, so the Wanderer enters with one +1/+1 counter for each colour of mana spent to cast it. It is the only card in Magic with a variable modular value.

Does Zabaz boost his own modular trigger?

No. His replacement effect requires him to be on the battlefield, and he has already left it when his own modular trigger resolves. He boosts everything else’s.

What is the best modular commander?

Zabaz, the Glimmerwasp, by a distance. He is the only legendary creature with modular that also cares about the mechanic, he costs one mana, and his Boros colour identity legally contains 21 of the 24 modular cards.

Is Arcbound Ravager still good?

In Modern, yes — it remains the mechanic’s only genuinely competitive card and the reason artifact aggro decks exist. In Commander it is good rather than essential, because a single sacrifice outlet on a 1/1 body does less in a hundred-card singleton format than it does in a four-of deck.

Do −1/−1 counters stop modular?

Not the trigger, but they do shrink the payout. If −1/−1 counters kill the creature, the +1/+1 counters remaining on it at that moment are what transfers — and the two counter types annihilate each other first, so there may be very few left. See our guide to −1/−1 counters and infect for how the annihilation rule works.

Where modular sits in 2026

Twenty-four cards in twenty-two years is a slow drip, and the drip has almost stopped: one card in 2019, eight in 2021, one in 2022, one in 2024, and nothing since. Modular is a mechanic Wizards keeps in the drawer for Modern Horizons sets, where it can print a genuinely powerful artifact card without disturbing Standard.

What that means practically is that the list above is close to complete and unlikely to move much. Twenty of the cards cost under a dollar, the mechanic has a real commander in Zabaz, and the deck it builds is one of the cheapest genuinely functional artifact decks in Commander. If you want to see what else counters can do, our guides to proliferate and to artifact token generators cover the two engines that pair with it best.
