@Ryougu Deadbridge Chant? That or Jarad's orders is the best I got.
And also, this too. Plus, where are the other Phyrexians?
<Snipped quote by Gemini Token>First up. Phyrexians. If they are even phyrexians they believe in one purpose, and that is to spread the glory of Phyrexia to everything else. Literally the only purpose of Phyrexia is to 'enlighten' everyone else in order to for Phyrexia to extend its reachs. They go about this is in mutiple ways such as full on attacking planes through planar bridges (Dominaria/Rathi Overlay) or through unseen corruption of the plane. (Mirroden) In the case of Dominaria, It caused huge huge huge problems for the entire plane for many hundreds of years. In terms of Mirroden. Well Mirroden doesn't exist anymore and is called New Phyrexia. So that explains something.
Secondly if any Phyrexian even was on Ravnica they would be from either New Phyrexia (which means they finally made planar bridge technology) or from old Phyrexia (which is basically impossible due to the destruction of the plane and the death of Yawgmoth). Now you could say that they were there for effectively ages but that creates another issue, Mirroden fell apart very quickly due to being an artifact plane but Ravnica is full of streets made narrow. Phyrexisis would be an infection that could easily spread through early ravnica. That would engrain the history of Ravnica however that would also mean Phyrexian substances like Ichor(Glistening Oil) would be in abundenance.
So unless the story is going New New Phyrexia I wouldn't recommend being a Phyrexian. The easy fix is just being something that has mutated itself through Simic experiments and now resembles a Phyrexia though with non of the doctrine or abilty to infest.
