The Commander

Whenever you cast a Phyrexian creature or artifact creature spell, incubate X, where X is that spell's mana value. (Create an Incubator token with X +1/+1 counters on it and " {2} : Transform this token." It transforms into a 0/0 Phyrexian artifact creature.)

At the beginning of each end step, if a Phyrexian died under your control this turn, proliferate.

Guide

Gameplan

Cast Phyrexian and artifact creatures to flood the board with Incubator tokens, then transform them into a growing army of Phyrexian bodies. Sacrifice and recur those Phyrexians to trigger proliferate each turn, snowballing +1/+1 counters across your board and enabling an aristocrats/go-wide assault that overwhelms the table.

Strengths

Generates free, scalable board presence every time you cast Phyrexians or artifact creatures
End-step proliferate compounds counters on Incubators, creatures, and any counter-based engines
Plays naturally as both an aristocrats sacrifice deck and a go-wide tokens deck
BW gives access to premium removal, recursion, and sacrifice payoffs

Weaknesses

Slow to start—needs creatures resolving and mana to transform Incubators
Board wipes are devastating since the strategy is creature-density dependent
Incubators are vulnerable to artifact removal before they transform
Proliferate trigger requires a Phyrexian to die, so off-theme creatures don't enable it
Relies on the commander to fuel value, making it tax-prone and removal-sensitive

Key Cards

Phyrexian Crusader — Cheap Phyrexian whose first strike and infect get terrifying as proliferate stacks counters.
Elesh Norn, Mother of Machines — Doubles your incubate and proliferate triggers while shutting off opponents' ETBs.
Skrelv, Defector Mite — A one-mana Phyrexian that protects Brimaz and triggers incubate immediately.
Pitiless Plunderer — Turns sacrificed Phyrexians into treasure, fueling more spells and transform costs.
Vindicate — Flexible BW removal that keeps the board clear so your army can connect.
Cathars' Crusade — Each token and creature entering pumps the whole team, and proliferate magnifies it.

Upgrade Path

Lean harder into cheap Phyrexians and artifact creatures so every cast triggers incubate, and add proliferate doublers like Elesh Norn and Roaring Earth-style payoffs. Tighten the aristocrats package (Pitiless Plunderer, Blood Artist, Bastion of Remembrance, free sac outlets like Viscera Seer) to guarantee the death trigger and convert bodies to value. Round out with efficient BW removal, a reanimation suite, and protection like Teferi's Protection to survive the board wipes that prey on this strategy.

Tokens / Go-Wide — Incubators flood the board and proliferate grows the army into a lethal swarm.
+1/+1 Counters — Proliferate every turn turns counter synergies and even infect/toxic into a real plan.
Reanimator — BW recursion replays big Phyrexians repeatedly for incubate value and sacrifice fodder.
