The most traditional way to win a game of Magic is to beat your opponents down to 0 life points. But there are also alternative win conditions, such as cards like Approach of the Second Sun or Mortal Combat.

One of those alternatives is to “mill” your opponent. Milling emphasizes putting your opponents’ cards from the library into the graveyard, or in exile. If a player runs out of cards in their library and must draw a card, they lose the game.

This mechanic doesn't see much play, but it's still present in some Eternal formats like Modern. It’s a strategy that's fun to pilot, with lots of secrets to unveil.

I've got a deck for you with just that win condition today. Let's check it out!

The Strategy

Like every mill deck, the strategy is simple: Reduce your opponents’ library to zero cards before they kill you. This task may prove a bit challenging, especially in a format where the top deck could be an 80-card 4-color elementals deck with Endurance as part of its primary plan.

I’ve seen this deck mill those 80-card decks twice in the same game, so rest assured that the strategy is sound.

The Creatures

This deck runs eight crabs. Hedron Crab and Ruin Crab are a core part of the mill strategy. Fetch lands let you double dip on landfall triggers, and there are nine total effects that can get you more than one land on the field per turn.

The deck doesn't need any other creatures. These little guys can block some of the most aggressive creatures in Modern like Ragavan, Nimble Pilferer or Goblin Guide pretty well.

The Removal

Fatal Push is a critical tool to stay alive. Aside from Murktide Regent, this spell can kill almost anything relevant, and triggering revolt is relatively easy.

Drown in the Loch is a catch-all spell that can either prevent something from resolving, or get rid a creature that was resolved earlier. Push and Drown form your go-to removal package for this deck.

The Mill Package

The crabs aren’t the only spells that mill your opponents.

Fractured Sanity is a flexible spell that can mill your opponent for a whole bunch when you pay the total price, or just a chunk by cycling it. This card has no downsides.

Tasha's Hideous Laughter is a high variance card: It can either mill half your opponents' library against low-curve decks, or just a handful of cards if they run expensive Eldrazi and such. The appeal is that those cards are exiled rather than put into the graveyard. This is huge because some strategies like Izzet () Murktide benefit from putting cards into the graveyard.

Archive Trap is an auto-include in any mill deck that’s played in a format that uses fetch lands so much.

Card Advantage

In this deck, Visions of Beyond does a startling Ancestral Recall impression.

Visions of Beyond can refill your hand for cheap to help snowball mill effects against your opponents. Jace, the Perfected Mind has a -2 ability that offers Visions of Beyond with mill or simple card draw as upsides. The +1 slows down your opponent's best attacker, and the potentially huge chunk of mill with the -X ability can close out games. Feel free to cast it for its compleated cost as soon as possible.

Utility Cards

Surgical Extraction can shut down critical cards from your opponent's deck. You can shut down entire strategies if you mill some of the key pieces. You might also exile one of their hate cards that got milled, which can be a game-changer.

Another great utility card is Consign to Memory, which has myriad uses. The Stifle mode handles evoke elementals' triggered abilities or storm triggers while taking out colorless spells, which is amazing flexibility especially now that Mox Opal has been released upon the greater format. It excels at handling Eldrazi as you can counter both the spell and any triggered abilities it has by replicating this card; replicate also allows you to effectively handle opposing countermagic because you can make a couple of copies if you suspect your opponent has a Dispel coming your way.

The Lands

The mana base is smooth as it can be: just the right mix of Dimir () fetch lands and shock lands. A couple of lands are excellent additions to a deck that can fully exploit their potential.

Field of Ruin excels in a format where almost every deck plays nonbasic lands. It’s also a way to force your opponents to search their libraries and make your Archive Trap cheaper.

My favorite of the bunch is Oboro, Palace in the Clouds. This is a beautiful piece of tech for a deck that runs eight crabs.

Otawara, Soaring City bounces some permanent that either aims to disrupt your plans or is a threat on its own.

Shelldock Isle keeps the momentum going with its ability to cast a hideaway spell for just 1 mana in the mid- to late-game.

Cephalid Coliseum might hurt along the way, but it can give you a burst of loots if needed, or force an opponent to draw three cards to wrap up the mill plan.

Tips and Interactions

Modern is a problematic format where testing new decks or brews can be tricky. Here are some tips and tricks from my experience to help you maximize this deck's potential:

• I am still surprised by the consistency of the mill package. You usually swap cards for others that are probably not very good in specific matches. This deck’s mill core is almost untouchable, so you tend to add a couple of cards that improve your matches.
• It’s usually good to lead with a turn 1 crab because your opponent could have difficulty dealing with it. If you face a deck with multiple removal spells, you may want to wait a turn until you have a land drop to follow the crab.
• Hate cards like Endurance are good to immediately remove from your opponent's graveyard with Extirpate. You can also do it with Surgical Extraction, but it might get tricky since they can cast another copy for free. Split second prevents that from happening.
• You run a mix of mill, removal, and counters, so don't tap out and try to play your mill spells at instant speed. This might seem intuitive, but it's important to be able to answer the threats that immediately kill you, like Colossus Hammer or Murktide Regent, rather than the ones that are mostly just annoying.

Sideboard Guide

Burn Matchups

Burn is a match where you’re up against their direct damage package. The crabs do an excellent job at blocking and keeping you in good health against most of their creatures. One card you may want to remove as soon as possible is Eidolon of the Great Revel because it's a static way to damage you if left unchecked.

Surgical Extraction is key when you can guess the card they may have in hand, and it can save you multiple life points in the end. Post-board you should replace them with Extirpate.

In

• +1 Ghost Quarter
• +3 Extirpate
• + 2 Engineered Explosives

Out

• -3 Surgical Extraction
• -3 Visions of Beyond

Ruby Storm

Ruby storm has some great starts, but you’re well equipped to handle the deck with your main deck Surgical Extractions messing up their game plan, which you can further pressure by bringing Extirpate. You’ll also lean on Consign to Memory as a powerful disruption tool; in addition to handling the namesake Ruby Medallion, it counters the actual storm trigger off Grapeshot, which can be all you need to deal with an opponent.

In

• +3 Extirpate
• +3 Consign to Memory

Out

• -4 Fatal Push
• -1 Visions of Beyond
• -1 Jace, the Perfected Mind

Izzet Murktide Matchups

The Murktide match is very fast, so you need to keep yourself healthy and answer threats like Ragavan, Nimble Pilferer and Murktide Regent. They also run some ways to disrupt your plays with counterspells. The best way to approach these decks is to kill their early threats and mill them as fast as you can by playing around counters as much as you can. Don’t neglect your Archive Trap!

Post-board you can slow down. If you manage to resolve Ensnaring Bridge, opponents may not be able to kill you, especially if you Extirpate their only way to deal with the bridge.

In

• +1 Ghost Quarter
• +3 Extirpate
• +2 Ensnaring Bridge
• +2 Engineered Explosives

Out

• -3 Surgical Extraction
• -1 Fatal Push
• -2 Visions of Beyond
• -1 Jace, the Perfected Mind
• -1 Glimpse the Unthinkable

Yawgmoth Matchups

Yawgmoth is a midrange deck that aims to assemble their combo with its signature card Yawgmoth, Thran Physician along with their undying creatures. Surgical Extraction and Extirpate are key cards against this deck as you need to exile their undying creatures when they hit the graveyard and with their ability on the stack.

Aside from that, just mill them like you would others, but be aware that most lists also run Endurance.

In

• + 1 Ghost Quarter
• +3 Extirpate
• +2 Crypt Incursion
• +1 Toxic Deluge

Out

• -2 Fatal Push
• -1 Visions of Beyond
• -3 Surgical Extraction
• -1 Glimpse the Unthinkable

Boros Energy

Boros Energy’s a terrifyingly fast deck even in a post-Amped Raptor Modern, but this deck has the tools to handle it. You can ditch the painful Surgical Extractions and the slow Visions of Beyond for a variety of interactive spells in the sideboard, including several board wipes. This helps you slow them down to your speed so you can mill them out.

In

• +2 Engineered Explosives
• +2 Toxic Deluge

Out

• -3 Surgical Extraction
• -1 Visions of Beyond

Living End Matchups

This match is polarizing because whoever is on the play may seem to have the advantage. If you know you’re playing against them, try to keep or mulligan into hands with Drown in the Loch, or Crypt Incursion post-board.

You can also aim to mill their Living End and exile it with your Surgical Extraction, but you shouldn't rely on that strategy alone. Still, it's a way to win that may come up occasionally.

Fatal Push doesn’t do anything here, so you can replace it with graveyard hate in Crypt Incursion and Ensnaring Bridge to stall their big creatures.

In

• +3 Extirpate
• +2 Crypt Incursion
• +2 Ensnaring Bridge

Out

• -4 Fatal Push
• -1 Tasha's Hideous Laughter
• -2 Visions of Beyond

How to Beat Dimir Mill

Beating this deck is like facing burn because you’ll feel like you’re running on a clock against it. The best way to kill them is to be fast and don't let the crabs stay on the battlefield for long. You can always kill them with the trigger of cracking a fetch on the stack so they don't mill you more than you need if they resolve.

An excellent sideboard card against this deck is Leyline of Sanctity since most of the mill package targets opponents. Another way to face this deck is to use hand disruption like Thoughtseize to slow the mill deck down and apply pressure to it with creatures.

Other Cards to Try

Ashiok, Dream Render

Three mana can be a bit expensive, but Ashiok, Dream Render’s ability to shut down some decks is huge. It’ll either make them unable to search their library or exile their graveyard. If your opponents don't answer it, they’ll lose a considerable chunk of their library.

Mesmeric Orb + Teferi's Tutelage

Mesmeric Orb and Teferi's Tutelage have a similar role by passively milling your opponents throughout the game. I don't like them much because they tend to be too slow for the format, but they could see play in some cases like against control decks.

Deepmuck Desperado is an honorary crab, and Dimir decks are notorious criminals and good at committing crimes. Realmbreaker, the Invasion Tree is a bit slow, but synergizes nicely with your crab's landfall triggers. The Ancient One is really interesting if you're up against even a little opposing mill, and the looting ability is a good option to have, even if your highest mana value discard option is Archive Trap.

The Mindskinner

A funny little card from Duskmourn, The Mindskinner was ostensibly printed as a new mono-blue commander, but that doesn’t mean you can’t have fun with it in Modern. If you were to try this out, you might want to run Jace's Phantasm and maybe even Cruel Somnophage for meaty creatures that aid the damaging mill plan. Of course, this comes with the weakness of adding a bunch of creatures that rely on The Mindskinner being in play for value, which hampers the deck’s consistency and opens your mill package to more forms of removal than it currently has. But you never know—that might be just the brew you need!

Wrap Up

Modern is a format where every strategy has its place. Mill can surprisingly have a terrific match-up against most of the field, but you need to do a lot of reps to get in sync with the tempo of the deck.
