Phyrexian Haze

Create an X/X Phyrexian creature token with indestructible and toxic 1, where X is equal to
the amount of Phyrexians you control.
All phyrexians you control get a +1/+1 counter
and gain toxic 1 permanently; added onto their
own toxic if they have it.
When a phyrexian enters the battlefield, gain 4
life.
