Brimaz, Blight of Oreskos serves as the engine of this deck, generating a growing army of Incubator tokens whenever Phyrexian or artifact creatures are cast, then proliferating those counters at end step whenever a Phyrexian dies, steadily transforming tokens into increasingly large Phyrexian artifact creatures. The deck supports this engine through a suite of artifact creatures, Splicers that produce indestructible Golem tokens, and recursion effects that repeatedly return creatures from the graveyard to trigger both Brimaz and enter-the-battlefield effects. Board wipes that leave artifact creatures standing, combined with the growing token army and proliferate acceleration, create an overwhelming board presence that wins through combat.
