Venser's Infect-Toxic Proliferate Combo

Why Play This Deck

Venser, Corpse Puppet is the most surgical poison-clock commander in Brawl. He arrives on turn 2 with lifelink and toxic 1, immediately starting two parallel clocks: draining your life total while stacking poison counters that proliferate spells then snowball into lethal territory. What makes this deck uniquely powerful is its redundancy — every cheap interaction spell doubles as a proliferate trigger via Flux Channeler and Inexorable Tide, meaning you never tap out just to remove a threat. You're always advancing the poison plan at the same time. The lifelink buffer from Venser and Skithiryx buys critical time against aggro, the dense counterspell suite protects your engines against control, and Vraska's Betrayal's Sting provides a one-card game-ender for any opponent already sitting on poison counters. Play this deck if you enjoy assembling interlocking engines, punishing opponents who ignore a 2-mana commander, and winning through a vector most decks have no dedicated answer for.

Play Summary

The game plan unfolds in three clean phases. In the early game (turns 1–3), prioritize deploying a mana rock on turn 1 or 2 — Arcane Signet, Dimir Signet, or Talisman of Dominance — then land Venser on turn 2 and start attacking immediately. Every unblocked Venser swing deals 1 poison and gains you life, so the clock is already running before you've cast a single proliferate spell. Supplement with cheap toxic creatures: Bilious Skulldweller on turn 1, Pestilent Syphoner or Blightbelly Rat on turn 2, Thrummingbird on turn 2. In the mid game (turns 4–6), layer your proliferate engines. Flux Channeler turns every subsequent instant and sorcery into a free proliferate. Inexorable Tide does the same for every spell you cast. Tekuthal, Inquiry Dominus doubles every proliferate trigger on the stack. With all three online, a single Tezzeret's Gambit advances poison counters by six or more. Use Diabolic Intent, Grim Tutor, and Insatiable Avarice to find whichever engine piece is missing. In the late game (turns 7–9), Vraska, Betrayal's Sting's ultimate closes out any opponent at 1–8 poison counters in a single activation, while Skithiryx provides a hasty infect finisher that can deal 4 poison in one unblocked swing. Leyline of Anticipation lets you hold up counterspells and still cast proliferate spells at instant speed on opponents' end steps, maximizing mana efficiency every single turn cycle.

Key Synergies

Opening Hand

The ideal opening hand has two lands covering both blue and black (a dual land or Command Tower plus a basic), one mana rock, Venser available to cast on turn 2, and at least one proliferate spell or cheap toxic creature as a follow-up. Brainstorm, Consider, and Experimental Augury are all excellent keeps because they find your missing pieces while triggering Flux Channeler once it lands. Mulligan any hand with zero interaction if you know you're facing an aggressive commander — you need at least one removal spell in hand before turn 3. Mulligan any four-land hand without a mana rock or two-drop, since flooding with no action in the first three turns lets opponents stabilize before your poison engine comes online. The best possible opener is Island plus Swamp plus Arcane Signet plus Venser plus any proliferate sorcery — that sequence attacks on turn 3 with Venser, casts the proliferate spell, and has already advanced poison counters twice before most opponents have played their commander.
