Brimaz turns every Phyrexian creature or artifact creature spell into a free Incubator token sized to that spell's mana value, so the deck is a midrange-to-big Phyrexian and artifact-creature shell that ramps into expensive bodies and floods the board with counters-laden Incubators. Sacrifice outlets and board wipes kill Phyrexians on purpose so Brimaz proliferates at end step, while reanimation and artifact recursion keep recasting or returning high-value creatures. Golem-making splicers, living weapon germs and incubators give a wide board of Phyrexian bodies to grow, protect and convert into damage. How it wins: It overwhelms opponents with a wide board of oversized Incubators, Golems and big Phyrexian threats, backed by lethal combat tricks like halving life totals, Myr pings and life drain from creatures dying. Key roles: - Big casts for big incubates: Expensive Phyrexian and artifact creatures double as large Brimaz incubate triggers, and mana rocks plus cost-reduction ramp into them quickly (Phyrexian Triniform, Myr Battlesphere, Ancient Stone Idol) - Golem and token army: Splicers and dying artifact giants spawn Phyrexian Golem tokens that buff one another with indestructible, first strike or +1/+1, turning each nontoken Phyrexian into more bodies (Darksteel Splicer, Master Splicer, Blade Splicer) - Sacrifice and proliferate engine: Sac outlets and germ fodder ensure a Phyrexian dies each turn so Brimaz proliferates, growing unflipped Incubators, counters and charge counters alongside other proliferate sources (Compleated Huntmaster, Filigree Vector, Karn's Bastion) - Reanimation and artifact recursion: Graveyard returns bring back fallen giants or loop artifacts, and historic casts let Moira and Teshar re-deploy permanents each turn (Moira and Teshar, Vulpine Harvester, Phyrexian Delver) - Asymmetric wipes: Sweepers that spare artifacts or leave a token behind clear opposing boards while Incubator-transformed Phyrexian artifacts survive, and also trigger the death proliferate (Phyrexian Scriptures, Phyrexian Rebirth, Massacre Wurm) - Closing finishers: Equipment and evasive threats convert the wide board into lethal damage (Scytheclaw, Nettlecyst, Vault of the Archangel)
