So Miracles stays. Thank you for not making a mistake, WOTC. I am inexplicably excited that it has stayed (not being sarcastic). But enough of that: are you now looking for a way to beat Miracles or the Eldrazi menace? Today I’ll be featuring another really fun deck that plays massive creatures-only this time, you are hard casting your Emrakul, the Aeons Torn.

TwelvePost – Boston Schatteman

Let’s get this out of the way first: Cloudpost is a broken card. The original core 12 Post manabase consisted of 4 Cloudpost, 4 Glimmerpost, and 4 Vesuva; however, current versions of the deck has become more of a 10-11 Post manabase. The main goal of this deck is to hard cast spells that other people like to cheat into play, because we are legit. Cloudpost is the main culprit for all this mayhem with its sidekicks of Glimmerpost and Vesuva. Cloudpost adds 1 colourless mana to your mana pool for each Locus in play. It so happens that Glimmerpost is a Locus and Vesuva can copy Cloudpost (which is also a Locus) without any cost like Thespian Stage. Getting Locuses into play will make your mana snowball out of control.

What We’re trying to Hard Cast

Emrakul, the Aeons TornKozilek, Butcher of TruthPrimeval TitanUlamog, the Ceaseless Hunger

You will be able to hard cast these guys when playing this deck. Pretty cool, right? Having multiple Locus Lands will allow us to make a lot of mana. For example, 1 Cloudpost will make 1 mana. 2 Cloudposts will make 4 mana. 3 Cloudposts will make 9 mana. 4 Cloudposts will make 16 mana. That’s a lot of mana. Casting these guys will get you very far ahead or end the game. Emrakul is Time Walk on a 15/15 stick. Kozilek is a better Ancestral Recall on a 12/12 stick. And Ulamog is 2 Vindicates on a 10/10 stick. This deck can not only hard cast the Eldrazi titans, but also occasionally cheat them into play.

Not as Fair as You Thought

Show and Tell

Show and Tell is also a very broken Magic card. This card was another serious mistake, but Wizards likes to keep it around because it makes Legacy more diverse. Sometimes we need Show and Tell to speed up our game plan if our hand is not capable of producing 6 mana quickly enough. Be careful though, for if you are playing against other decks with Emrakul, the Aeons Torn or Griselbrand they can attack first.

Combo Time!

Primeval Titan

“Prime Time,” we call this guy. Primeval Titan is the one-card combo of the deck. Once a Primeval Titan hits the board the game can end on the next turn or the turn after.

Start the combo by getting Prime Time on the board. Go and find Eye of Ugin and Karakas or get another Cloudpost if you don’t have enough mana to use your Eye and cast what you find with it.

When you have the mana, activate the Eye and find Emrakul, the Aeons Torn, then hard cast Emrakul and take an extra turn. If you haven’t found Karakas by now, find it by attacking with your Prime Time. Once you have Emrakul and Karakas you have infinite turns and your opponent has no more fun.

More Mana?

Candelabra of Tawnos

Yes, we just like to make so much mana-so much so that we can find Emrakul, the Aeons Torn and cast it in the same turn! We can do that with enough Cloudposts or we can just use this cheap artifact. Think about it: untapping our Cloudposts using Cloudposts. Now you are getting multiple uses out of each Cloudpost, netting a heap of mana. This artifact helps us get double green for Primeval Titan or cast our high end Eldrazi.

Finding our Mana

With only 12 key cards, you’ll need some ways to find them. Trinket Mage is here to find Sensei’s Divining Top, Expedition Map, or Candelabra of Tawnos. The rest of our card filtering is here to find your Post lands to make more mana. Brainstorm and Thirst for Knowledge can also double to find your protection spells. These cards and the number of them are in the deck because the deck is naturally slow and inconsistent and we need some way to improve its speed and consistency.

Utility Lands

Crop RotationBojuka BogKarakas

Crop Rotation is instant speed and can get any land. It can get Bojuka Bog to damage graveyard-based decks, Glacial Chasm to hose decks that win with damage and don’t play Wasteland like Burn and Infect, or Karakas to stop giant legendary creatures like Griselbrand or Emrakul, the Aeons Torn that fit in decks like Reanimator or Show and Tell. Karakas can also bounce Thalia, Guardian of Thraben to release some of the pressure she can put on you.


Since this deck doesn’t run a high density of counterspells, Cavern of Souls is a great way to auto-win counter wars. Normally you get Primeval Titan through with Cavern, but sometimes you also use it for Eldrazi or Trinket Mage. When you need to resolve a spell and can’t use Cavern or there’s a threat you need to deal with, Force of Will and Flusterstorm are there to fight for you. Repeal and All Is Dust can remove almost anything from the board. Pithing Needle is only here to shut down Wasteland, which can seriously damage your strategy by blowing up merely a single Cloudpost. Other great names for Needle after Wasteland are Rishadan Port or Sneak Attack.

Game Plan

Early Game (Turns 1-3): During the first three turns of the game you will be setting up your mana. Find Cloudposts and Vesuvas with your Brainstorms, Sensei’s Divining Tops, and Crop Rotations to start making large amounts of mana, and try to protect that mana with Pithing Needle.

Mid Game (Turns 3-6): These are the turns that you spend casting Primeval Titan, Show and Tell, or Eldrazi. These turns will likely dictate the game if it is not already decided.

Late Game (Turns 7+): The late game for this deck isn’t very weak. By now you want to be attacking with your massive Eldrazi or ending the game with Prime Time, unless you’ve been disrupted by Wasteland, Rishadan Port, or taxation effects like Thalia, Guardian of Thraben, or you’ve developed your board slowly to protect threats like Prime Time.

Variants of 12 Post

Mono Green 12 Post

Mono Green 12 Post cuts most of the cantrips and Show and Tell. In turn it gets to ramp not with just Posts, making it less vulnerable to Wasteland and Rishadan Port. The deck uses Oracle of Mul Daya, Veteran Explorer, and Green Sun’s Zenith in combination with Dryad Arbor as an additional ramp package, sometimes also with Explore and/or Exploration. This version more commonly runs sweepers such as All is Dust and Oblivion Stone and uses Ancient Stirrings to find them plus post lands, Eldrazi, or Candelabra of Tawnos. It usually also runs the Dark Depths and Thespian’s Stage combo in the deck to have another way of winning. None of the cards involved in the combo hinder the performance of the deck, because Thespian’s Stage can just become another Cloudpost and the deck generates enough mana to use Dark Depths manually pretty quickly.


MUD is is a colourless prison deck that aims to have very explosive mana through Cloudpost and pieces like Sol lands, Grim Monolith, and Metalworker to power out Kuldotha Forgemaster and Blightsteel Colossus. It also runs a variety of lock pieces like Chalice of the Void, Trinisphere, and Lodestone Golem. The only real similarity between MUD and 12 Post is the mana base, so MUD is a deck for another article.

Tips and Tricks

Crop Rotation is instant speed. This means in response to a reanimation spell you can crop rotate for a Bojuka Bog to fizzle the spell, giving you a good shot at winning the game. You can also get Karakas to bounce Griselbrand, Iona, or Emrakul, or get Glacial Chasm to stop a massive Price of Progress or a game-winning Craterhoof Behemoth attack. Use Crop Rotation in response to Wasteland to keep all your lands intact.

Repeal can pick up your Candelabra of Tawnos so that you can re-play it and use it to untap more lands again, all while drawing a card.

Use fetchlands, Expedition Map, or Crop Rotation to shuffle away bad Sensei’s Divining Top spins or the two cards you put back with Brainstorm.

Brainstorm serves three purposes in this deck: finding mana, finding the cards that progress your game plan, and finding cards that protect your game plan. Specifically in 12 Post are the roles of Brainstorm so opposite that you must make sure to always Brainstorm optimally.

Best names for Pithing Needle in the blind are Wasteland, Wasteland, and Wasteland! Sometimes you can name fetchlands to mess with an opponent who is not playing Wasteland.


Miracles: Very Favorable (80:20)

Miracles is the deck you will most often find and most often crush. Being a control deck, it relies on answering threats instead of racing them, using the Counterbalance/Sensei’s Divining Top soft lock as a crucial part of its counter magic suite. Beyond that, it runs 1-2 Counterspell and 4 Force of Will. 12 Post can ignore the Counter Top lock with all the Eldrazi you will be casting. Just hope they don’t flip Terminus to your Primeval Titan. Even then, you have Cavern of Souls to ignore all their counter magic and stick Primeval Titan, and (as I said before) if a Prime Time hits the board you are a heavy favorite to win. Otherwise, your Eldrazi have massive impact even when they are cast, so their counter magic only stems the bleeding.


Trinisphere and Chalice of the Void are good against Miracles as they shut off some of their subtle card advantage created by being able to cast multiple spells per turn. Krosan Grip can take out Sensei’s Divining Top, hindering their draws and stopping instant-speed Terminus or Entreat the Angels. You can also use Surgical Extraction to take out Force of Will, Swords to Plowshares, or Terminus if you are feeling greedy.

Eldrazi: Favorable (60:40)

Eldrazi aims to play somewhat like a Delver strategy that disrupts you after sticking a threat-except Eldrazi plays one piece of disruption, then starts dropping Thought-Knot Seers, Reality Smashers, and large Endless Ones. Their Chalice of the Void and Thorn of Amethyst can be annoying and disrupt your early development but they don’t stop your big stuff. Thought-Knot Seer is also a problem. It can take your Show and Tells, Primeval Titans, or Eldrazi before you get a chance to play them. From there, Eldrazi pressures you with some large creatures and can close out the game pretty fast. However, you are a deck built to stave off quick starts with Glimmerpost and Glacial Chasm to give yourself a cushion to withstand the speed of aggressive decks in the format. Show and Tell is one way of just going faster than them and getting Primeval Titan or an Eldrazi titan to mop up. From there you can generally capitalize on your narrow escape from getting crushed by a swarm of Eldrazi by throwing down the Eldrazi Titans Emrakul, Kozilek, and Ulamog to close out the game.


You want to find Glacial Chasm or multiple Glimmerposts as quickly as possible in this matchup. The last Crop Rotation is great for finding Glacial Chasm as well as the other big sideboard card in this matchup: The Tabernacle at Pendrell Vale. Tabernacle can pressure your opponent’s life total if they are using Ancient Tomb to pay it given that there are many cards that Eldrazi plays that cause them to lose life. Tabernacle also hinders their ability to deploy threats if they want to keep cards on board. Ensnaring Bridge will almost always mean certain victory if you can empty your hand.

Shardless BUG: Unfavorable (30:70)

This matchup looks much better when you write it out. In reality, it is pretty bad. Shardless BUG can throw Thoughtseize and Hymn to Tourach at you over the first few turns, stripping you of your developmental pieces and your business spells. The deck also plays 2-3 Wastelands to attack your manabase. It can then start deploying Tarmogoyfs, Lilianas, and Shardless Agents and use Ancestral Vision to refill and deploy more threats and disruption. Most Shardless BUG lists also play Maelstrom Pulse which can stop your fun with Primeval Titan or your Eldrazi that aren’t Emrakul. Since 12 Post’s optimal game plan hopes that the opponent lacks disruption, you are not favoured in this matchup.


The Tabernacle at Pendrell Vale can tax the Shardless BUG player and also tax their Wastelands. Flusterstorm can aid in defending your hand and thus defending you mana as well. All is Dust is a great reset button to let you to gain some breathing room and start deploying Primeval Titans and Eldrazi.

Storm: Unfavorable (30:70)

Your ANT matchup is abysmal. They can slow you down with Cabal Therapy and Duress so that they have time to set up and go for a certain Tendrils of Agony for lethal. You just aren’t fast enough to kill them before they kill you. The TES matchup is different, though, since they usually go off via Empty the Warrens and it is harder for them to get a lethal Tendrils. This gives you a chance to stick a Primeval Titan quickly (likely through Show and Tell) and grab some Glimmerposts to get out of reach of several goblins. Still, the matchup is not great.


Trinisphere and Chalice of the Void are your best friends in this matchup. With these you will be able to capitalize on your opponent’s now over-costed spells and win with Primeval Titan and Eldrazi. Mindbreak Trap and Flusterstorm are also all-stars in this matchup, being able to stop an entire stack of Tendrils of Agony or Empty the Warrens. If you are playing against TES you could also board in The Tabernacle at Pendrell Vale to trim down a horde of goblins to only a few.

Burn: Unfavorable (40:60)

Burn is a deck that you may think you have absolutely no way of beating. However, it is very possible to beat it. With the way your mana is set up you can get to your Glimmerposts quickly enough to stay alive. This will help soften the blow from cards like Price of Progress and Fireblast. You can also can use a turn 3 Show and Tell to get Primeval Titan or Emrakul, the Aeons Torn, both of which can easily trump the Burn player. In this matchup you want to save your Crop Rotation to get Glacial Chasm in the face of lethal burn or a big Price of Progress.


The recurring theme of Trinisphere and Chalice of the Void continues. Flusterstorm and Swan Song are great for countering Price and Fireblast. They can also catch some early stuff so that you can try to capitalize on your opponent’s lack of progress. The extra Crop Rotation comes in to get Glacial Chasm.

Death and Taxes: Slightly Unfavorable (45:55)

Death and Taxes is designed to bottleneck your mana, and the cards they use to do that can prove very effective against 12 Post. Wasteland and Rishadan Port are potent at attacking your Cloudposts, effectively corking your mana. However, Pithing Needle is an all-star in this matchup, letting you shut off Wasteland and Rishadan Port and unleash the crazy amounts of mana this deck is able to produce. Death and Taxes is the aggressor in the matchup and they will be able to play a Delver-esque game plan disrupting you as well as attacking, so you will be pressured to get your mana online fast. The Show and Tell plan is relatively effective against Death and Taxes because they don’t have anything to put down that competes with Primeval Titan. Also, they can’t do much to stop Show and Tell unless they can prevent you from casting it.


The 4th copy of Pithing Needle is a lock to come in against Death and Taxes to protect your mana from disruption. All is Dust can come in to tear through four creatures on the other side of the board, giving you a lot of breathing room and time. The Tabernacle at Pendrell Vale along with an extra Crop Rotation can come in to downsize your opponent’s board as well. Krosan Grip can chew up equipment found by Stoneforge Mystic and give you time and breathing room. You also want to bring in Swan Song to stop a possible Cataclysm that would surely destroy you.

Sneak and Show: Very Favorable (80:20)

This is hilariously a great matchup for 12 Post. Your Pithing Needles get their Sneak Attacks and their Show and Tells are pretty risky because you will be able to attack with your Emrakul, the Aeons Torn first. That said, you should refrain from casting your own Show and Tells for exactly that reason. With your Pithing Needles and your own giants to abuse Show and Tell with you are playing a role in this matchup very similar to Death and Taxes, which can shut down Sneak Attack and prevent their opponent from casting cantrips and Show and Tell by heavily taxing them.


You will want Trinisphere again to force your opponent to play with overcosted spells. You will also want Swan Song for insurance against a well-timed Show and Tell, a “Sneak Attack” that is not under a Pithing Needle, or the death sentence of Blood Moon. Speaking of Pithing Needle, you will want to bring in the 4th copy of it to get Sneak Attack and redundant ones can go towards hitting fetchlands or Jace, the Mind Sculptor as some lists play him. Flusterstorm also comes in to help win counter wars against stuff like Show and Tell, Blood Moon or Jace. Ensnaring Bridge is a hard lock if they don’t have alternate win conditions.

Delver Variants: Even (50:50)

Delver decks can throw a lot of disruption at you while putting you on a quick clock. It’s a matter of if you can overcome their disruption in time. While Delver is not as equipped to disrupt your mana as much as Death and Taxes is, it is more equipped to deal with your spells. We can make our Eldrazi and Primeval Titans resolve through Cavern of Souls and that will likely end the game.


After board we get Trinisphere again; if it sticks, it is devastating against Delver decks. The Tabernacle at Pendrell Vale can heavily disrupt them and slow them down. Flusterstorm can help us resolve our big spells and end the game.
