Here's how the deck looks with the upgrades added: Further Upgrades There's a bunch of heavy-hitter Phyrexians you can toss in the top-end: Elesh Norn, Mother of Machines and Mondrak, Glory Dominus both double the amount of tokens you're incubating with Brimaz which is super sweet, Elesh Norn is a great anthem for incubation, plus there's Sheoldred, Sheoldred, Whispering One, Sheoldred, the Apocalypse (lots of Sheoldreds!),Wurmcoil Engine, Skithiryx, the Blight Dragon
Odyssey Call of the Herd Dogged Hunter Elephant Ambush Kirtar's Wrath Dogged Hunter was the first card to interact with creature tokens (it can destroy them) rather than create them
