Brimaz, Blight of Oreskos

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
artifact.” 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.
