Phyrexian

This is a 5-color Phyrexian-themed Commander deck that plays like a value-driven midrange/superfriends build, centered on powerful proliferate, ETB, and praetor synergies. With cards like Atraxa, Praetors' Voice, Atraxa, Grand Unifier, Tekuthal, Ichormoon Gauntlet, and Mondrak, it wants to ramp into big threats, generate counters and extra value, then snowball the board.

Key synergies include proliferating planeswalker loyalty and +1/+1 counters, doubling token/value output with Mondrak, and abusing enters-the-battlefield effects with Elesh Norn, Mother of Machines. Atraxa, Grand Unifier and Jin-Gitaxias provide huge card advantage, while Elesh Norn, Grand Cenobite and large Phyrexian creatures help close games through overwhelming board presence. The deck generally wins by ramping into its high-impact legends, controlling the table with counters/removal, and burying opponents under repeated value and superior board states.
