Best poison & infect commanders

Ten poison counters and a player loses — no matter how much life they have. In a format where everyone starts at 40 life, that is a shortcut. Here are ten commanders for poison decks: some poison players themselves, others proliferate the counters your creatures leave behind.

The 10 best Poison & Infect commanders

We started from commanders that players build often for this theme on EDHREC. The order is our own: how well the commander fits the theme, how consistently the deck does its thing, how hard it is to stop, and how it holds up at a four-player table. It is not a popularity ranking, and no win rates are involved.

  • Beginner-friendly A clear plan with few decisions per turn
  • Budget-friendly The commander is inexpensive and the deck works without pricey staples
  • High power Among the strongest versions of the theme
Atraxa, Praetors' Voice — Magic: The Gathering card
1

Atraxa, Praetors' Voice

Complexity: MediumHigh power

Atraxa gives out no poison herself — she proliferates at the beginning of your end step, every turn. Each opponent who has a poison counter gets another, so one hit from an infect or toxic creature becomes a clock that keeps ticking. Four colors give you the best infect creatures, every proliferate card and plenty of removal, and her own flying, vigilance, deathtouch and lifelink make her a strong blocker while the counters pile up.

Strengths

  • A proliferate every turn without spending a card
  • Four colors: the widest choice of infect, toxic and proliferate
  • Excellent defense

Watch out for

  • No poison of her own — the deck must land the first counter
  • Four-color mana and one of the priciest commanders here

Best for: Players who want the strongest and most flexible poison deck.

Skithiryx, the Blight Dragon — Magic: The Gathering card
2

Skithiryx, the Blight Dragon

Complexity: LowBeginner-friendly

Skithiryx has infect: its combat damage to players is poison counters. A 4/4 flyer needs three hits to give a player ten counters — two with a little pump. {B} gives it haste and {B}{B} regenerates it, so it can attack the turn it comes down and survives destroy effects. Build around Equipment and Auras that pump it, and it plays like a Voltron deck that needs 10 instead of 21.

Strengths

  • Ten poison counters instead of 21 commander damage
  • Flying, haste on demand and regeneration
  • A simple, direct plan

Watch out for

  • Mono-black has fewer pump spells than green
  • Regeneration doesn’t stop exile or bounce

Best for: Newcomers to poison and Voltron players.

Ixhel, Scion of Atraxa — Magic: The Gathering card
3

Ixhel, Scion of Atraxa

Complexity: MediumBudget-friendly

Ixhel is a 2/5 flyer with toxic 2, so two hits leave an opponent corrupted — at three or more poison counters. From then on, at the beginning of your end step each corrupted opponent exiles their top card face down, and you may play it, spending mana as though it were any color. Poison becomes card advantage long before it wins. Abzan brings proliferate, removal and more toxic creatures.

Strengths

  • Evasive and hard to kill in combat
  • Card advantage from every corrupted opponent
  • Abzan removal and proliferate

Watch out for

  • Toxic 2 alone needs five hits per player
  • Two power: her damage barely matters

Best for: Players who want value from poison, not only a race.

Fynn, the Fangbearer — Magic: The Gathering card
4

Fynn, the Fangbearer

Complexity: LowBeginner-friendlyBudget-friendly

Fynn doesn’t use infect or toxic. Whenever a creature you control with deathtouch deals combat damage to a player, that player gets two poison counters. Deathtouch creatures are bad to block, so they connect, and five hits from them kill a player. Basilisk Collar and other deathtouch Equipment turn any creature into a poison source. At two mana Fynn is out early, and mono-green keeps the deck cheap.

Strengths

  • Two mana, out on turn two
  • Deathtouch makes blocking costly
  • Mono-green and inexpensive

Watch out for

  • Only creatures with deathtouch give poison
  • No evasion: big boards stop deathtouch attackers too

Best for: Players who want a cheap, straightforward poison deck.

Vishgraz, the Doomhive — Magic: The Gathering card
5

Vishgraz, the Doomhive

Complexity: MediumBudget-friendly

Vishgraz brings three Phyrexian Mite tokens with toxic 1 when he enters, and he has menace and toxic 1 himself. He gets +1/+1 for each poison counter your opponents have — all of them, so he grows as the whole table gets poisoned. Many small toxic attackers plus a few proliferate cards give each player counters quickly. Abzan adds token makers and removal.

Strengths

  • Four toxic bodies from one card
  • Grows with every poison counter on the table
  • Menace helps him connect

Watch out for

  • Toxic 1 per creature is slow without proliferate
  • The Mites can’t block

Best for: Players who like going wide.

Karumonix, the Rat King — Magic: The Gathering card
6

Karumonix, the Rat King

Complexity: LowBeginner-friendlyBudget-friendly

Karumonix gives every other Rat you control toxic 1, and when he enters he looks at the top five cards and takes all the Rats among them. Relentless Rats and Rat Colony let a deck run any number of copies, so the Rats come in numbers and every one of them poisons. Mono-black is simple, and most Rats are cheap. A typal deck with a poison twist.

Strengths

  • Refills your hand when he enters
  • Every Rat poisons
  • Mono-black and cheap

Watch out for

  • Toxic 1 per Rat takes many attacks
  • Rats are small and fold to board wipes

Best for: Players who like typal decks and unusual themes.

Kilo, Apogee Mind — Magic: The Gathering card
7

Kilo, Apogee Mind

Complexity: HighBudget-friendly

Kilo proliferates whenever he becomes tapped — by attacking, with his haste the turn he arrives, or by tapping for crew, convoke or untap tricks. Each untap effect is another proliferate. He gives no poison himself, so in a poison deck he grows the counters toxic Phyrexians left behind, along with your +1/+1 counters and planeswalkers. Jeskai has the fewest poison creatures, which makes this the most demanding build here.

Strengths

  • Proliferates the turn he comes down
  • Untap effects mean several proliferates a turn
  • Works with every kind of counter

Watch out for

  • No poison of his own
  • Jeskai has few infect and toxic creatures

Best for: Experienced players who like engines and combos.

Venser, Corpse Puppet — Magic: The Gathering card
8

Venser, Corpse Puppet

Complexity: MediumBudget-friendly

Venser has toxic 1 and lifelink, and whenever you proliferate he gives you a choice: create The Hollow Sentinel, a 3/3 Golem token, if you don’t have it, or give an artifact creature flying and lifelink until end of turn. Dimir has many proliferate spells, such as Tezzeret’s Gambit, so each one adds poison and a body or evasion. Two mana, a slow but steady control deck.

Strengths

  • Two mana, active early
  • Every proliferate does something extra
  • Dimir card draw and counterspells

Watch out for

  • Only one point of poison per hit from himself
  • Needs many proliferate cards to keep pace

Best for: Control players who like poison as a win condition.

Brimaz, Blight of Oreskos — Magic: The Gathering card
9

Brimaz, Blight of Oreskos

Complexity: MediumBudget-friendly

Brimaz deals no poison and has no toxic. He rewards Phyrexians: each Phyrexian creature or artifact creature spell you cast also incubates, giving you a second body, and at each end step after a Phyrexian of yours died he proliferates. In a poison deck the poison comes from toxic Phyrexians in the 99, and Brimaz doubles them and grows the counters. Orzhov adds sacrifice outlets to make Phyrexians die on purpose.

Strengths

  • Two bodies for every Phyrexian spell
  • Proliferate whenever a Phyrexian dies
  • Orzhov removal and sacrifice

Watch out for

  • No poison or toxic of his own
  • The proliferate needs a Phyrexian to die that turn

Best for: Players who want a Phyrexian deck with poison as one plan.

High Perfect Morcant — Magic: The Gathering card
10

High Perfect Morcant

Complexity: HighBudget-friendly

Morcant makes each opponent put a -1/-1 counter on a creature whenever an Elf enters under your control, and three untapped Elves tap to proliferate. He has no poison of his own: in a poison deck, Glistener Elf and other infect or toxic creatures give the first counters, and every proliferate adds to them while shrinking opposing creatures. A Golgari deck with two jobs for every Elf.

Strengths

  • Repeatable proliferate from your Elves
  • Shrinks opponents’ creatures along the way
  • Golgari: the best infect colors

Watch out for

  • No poison of his own
  • Needs Elves and poison sources at once

Best for: Players who want an Elf deck that wins with poison.

How does poison work in Commander?

A player with ten or more poison counters loses the game, whatever their life total. Commander starts everyone at 40 life, so ten counters is a much shorter road — and lifegain doesn’t help against it. Poison counters stay for the whole game.

Poison, infect, toxic and proliferate — not the same thing

  • Infect: the creature deals damage to players as poison counters and to creatures as -1/-1 counters. It deals no normal damage at all.
  • Toxic N: the creature deals normal combat damage, and a player it damages also gets N poison counters. Toxic only works in combat.
  • Other poison effects: Fynn gives two counters for deathtouch hits; some spells give poison counters directly.
  • Proliferate adds one more counter of each kind that a player or permanent already has. It doesn’t start poison — it multiplies it. Corrupted abilities turn on once an opponent has three or more poison counters.

How a poison deck wins

  • Infect beats: a few evasive infect creatures with pump spells. Triumph of the Hordes gives the whole team infect for one turn.
  • Toxic and proliferate: many small poison sources, then proliferate every turn until the counters add up.
  • A poison commander: Skithiryx needs three hits, fewer with pump.

Strengths and weaknesses

Poison ignores life totals and lifegain, and it often needs only half the damage. But infect creatures are small and fragile, and a deck split between normal damage and poison wins with neither. Many tables also see poison as a hostile plan and turn on it early — say before the game that you play it.

Common mistakes

  • Too few poison sources. Proliferate does nothing until the first counter lands.
  • Spreading counters evenly. Finishing one player is better than three players at six counters each.
  • Mixing plans. A few infect creatures in a normal deck rarely finish anyone.

Who enjoys poison?

Players who like an alternative win condition and counting to ten instead of 160. It rewards focus: pick a target and keep pressure on it.

Questions about Poison & Infect commanders

What is the difference between poison, infect and toxic?

Poison counters are what make a player lose at ten. Infect is a keyword that deals all damage as poison counters (to players) and -1/-1 counters (to creatures). Toxic deals normal damage and adds a fixed number of poison counters. Proliferate adds one more of each counter that is already there.

How many poison counters does it take to lose in Commander?

Ten, the same as in every other format. Commander’s 40 life doesn’t change it, which is why poison is a shortcut in this format.

Does proliferate add poison counters?

Yes. Proliferate lets you choose any players and permanents that already have counters and give each another counter of each kind — poison counters on opponents included.

Who is the best poison commander?

Atraxa, Praetors’ Voice for the strongest and most flexible deck, because she proliferates every turn in four colors. Skithiryx is the simplest, Fynn and Karumonix the cheapest.

Are poison decks good in Commander?

They can be very fast, because ten counters is far less than 40 life. They are also fragile and often draw attention, so they work best with protection and a clear target each turn.

Can you build a budget poison deck?

Yes. Most infect and toxic creatures are inexpensive. Fynn, Karumonix and Vishgraz all work on a budget, and Commandarium shows what you already own and what the rest costs.
