Precon Upgrade Guide
What to cut, what to add, and how to play the Jeskai artifacts and proliferate precon from Edge of Eternities, commanded by Inspirit, Flagship Vessel.

Edge of Eternities
Counter Intelligence
Counters spread across creatures and Spacecraft alike. Out of the box, before any upgrades. How we rate precons
Buy Counter Intelligence on TCGplayer →Counter Intelligence is an artifact deck where nearly every permanent carries counters and the deck keeps adding more. Inspirit, Flagship Vessel puts counters on an artifact every combat, and once fully stationed it makes your other artifacts hexproof and indestructible. The box has a lot of proliferate and a few strong payoffs like Lux Artillery and Darksteel Reactor . It is held back by a mana base with many tapped lands, board wipes that hit your own artifact creatures, and a few slow artifacts that don't add much to the counters plan.
TurnZero HQ rates Counter Intelligence a 3 out of 5 on difficulty and a 3 out of 5 on power, as it comes in the box. That is our editorial read, not an official Wizards rating. The full hundred cards are on the Counter Intelligence decklist page, and every other precon we cover is on the precon directory.
Inspirit, Flagship Vessel is a three-mana Spacecraft. With at least 1 charge counter, at the beginning of combat on your turn it puts either a +1/+1 counter or two charge counters on up to one other target artifact. You station it by tapping another creature at sorcery speed, adding charge counters equal to that creature's power. At 8 counters it becomes a 5/5 flying artifact creature, and your other artifacts gain hexproof and indestructible.
Most of the deck grows those counters. Tekuthal, Inquiry Dominus doubles every proliferate, and Surge Conductor , Kilo, Apogee Mind , Experimental Augury and Karn's Bastion proliferate on their own. Kilo is a good creature to station with, since tapping it to station Inspirit also proliferates.
The counters pay off in several places. Lux Artillery deals 10 damage to each opponent at your end step once you have thirty counters among your artifacts and creatures, Darksteel Reactor wins at twenty charge counters, and Insight Engine , Titan Forge and Empowered Autogenerator turn charge counters into cards, 9/9 Golems and mana.
Inspirit, Flagship Vessel ↗
Adds counters to an artifact every combat, and at 8 charge counters gives your other artifacts hexproof and indestructible, which protects the whole board.
Tekuthal, Inquiry Dominus ↗
Makes every proliferate happen twice. With the box's many proliferate effects, counters grow twice as fast.
Kilo, Apogee Mind ↗
Proliferates whenever it becomes tapped, including when you tap it to station Inspirit or to attack.
Lux Artillery ↗
Gives artifact creatures sunburst, and at your end step deals 10 damage to each opponent if you have thirty or more counters among your artifacts and creatures. A counters deck reaches that number.
Surge Conductor ↗
A three-mana artifact creature that proliferates whenever another nontoken artifact enters under your control. In this deck that is most turns.
Insight Engine ↗
Adds a charge counter and draws a card per counter each activation. Proliferate speeds it up, so it becomes a large draw engine.
The mana base has more tapped lands than a three-color deck should run. Three temples, Irrigated Farmland , Mystic Monastery , Glittering Massif , Lonely Sandbar , Secluded Steppe and the three artifact bridges all enter tapped. The bridges at least count as artifacts; the rest just cost you tempo.
Two of the wipes, Fumigate and Chain Reaction , kill your own artifact creatures along with everyone else's. The deck also has only Swan Song to stop a spell, which leaves its artifact board open to an opponent's wipe before Inspirit is stationed.
Each upgrade below starts from something the deck does poorly and says what a replacement card has to do. The cards named are examples, not the only answer: if you own something else that does the same job, or a newer printing does it better, it goes in the same slot. Make one change at a time and play a few games between them, so you can tell which change helped. The general method is in how to upgrade a Commander precon →
Inspirit costs three and wants to be stationed early. A deck with this many tapped lands loses a turn of development in most games.
What to look for Two-color lands in Jeskai pairs that enter untapped early: fastlands, painlands or shocklands. Keep the artifact lands, which help affinity and metalcraft cards.
Cut, for example
Temple of Enlightenment Always enters tapped. Scry 1 is a poor trade for a slow start.
Temple of Epiphany The same tapped land in blue-red.
Temple of Triumph The same tapped land in red-white.
Every payoff in the deck counts counters, and proliferate grows all of them at once. More cheap proliferate effects make Lux Artillery, Darksteel Reactor and Insight Engine arrive sooner.
What to look for Cheap creatures or spells that proliferate repeatedly, ideally triggered by something the deck already does.
Cut, for example
Long-Range Sensor Gets a charge counter each time you attack, then trades two for a discover 4. The deck doesn't attack often enough early for it to do much.
Cloud Key Makes one card type cost one less. Etherium Sculptor and Enthusiastic Mechanaut already reduce artifact costs as creatures that can station Inspirit.
Add, for example
Flux Channeler ↗
Three mana: proliferate whenever you cast a noncreature spell. Every noncreature artifact and instant in the deck triggers it.
Grateful Apparition ↗
Two mana for a 1/1 flier that proliferates when it deals combat damage to a player or planeswalker. A second copy of Thrummingbird's effect.
Your board is mostly artifacts and artifact creatures. A wipe that kills your own creatures is a poor trade, while a counterspell protects the whole board from an opponent's wipe.
What to look for Counterspells for two mana or less, especially ones that stop noncreature spells, since board wipes are usually sorceries.
Cut, for example
Chain Reaction Deals damage to each creature equal to the number of creatures on the battlefield. It kills your artifact creatures as easily as anyone else's.
Fumigate Destroys all creatures. Organic Extinction already covers this job and spares artifact creatures.
Add, for example
Counterspell ↗
Two mana, counters anything.
Dovin's Veto ↗
Two mana to counter a noncreature spell, and it can't be countered. It stops board wipes and artifact removal.
Arcane Denial ↗
Two mana to counter any spell. Its controller draws up to two cards at the next upkeep, which is a fair price for stopping a wipe.
Some of the deck's top end costs too much for what it adds. Artifact creatures that enter with +1/+1 counters fit every stage of the game and grow with proliferate.
What to look for Artifact creatures with X costs or +1/+1 counters, which you can cast early for a small body or late for a big one.
Cut, for example
Wake the Past Seven mana to return all artifact cards from your graveyard. It only matters after a wipe has already hit you, and it costs most of a turn.
Mindless Automaton A four-mana 2/2 that turns discards into counters and counters into cards. It is slow next to the deck's other draw engines.
Add, for example
Walking Ballista ↗
Enters with X +1/+1 counters, and each counter can be removed to deal 1 damage to any target. Proliferate refills it, so it doubles as removal and a finisher.
Stonecoil Serpent ↗
An X-cost artifact creature with reach, trample and protection from multicolored. It is as big as you need it to be and grows with proliferate.
The deck wins through its counter payoffs. Lux Artillery deals 10 to each opponent once you reach thirty counters, Darksteel Reactor wins outright at twenty charge counters, and Titan Forge makes 9/9 Golems for combat. Alibou, Ancient Witness deals damage when your artifact creatures attack. A fully stationed Inspirit keeps all of these safe from removal, so the upgrades focus on getting there and protecting the board in the meantime.
A good fit for a player who has played a few precons and likes engine decks. There are a lot of counters to track and many small choices about which permanents to proliferate, so the deck asks for attention every turn. It suits someone who enjoys building toward a big payoff more than attacking early.
