Cultist Gathering

As long as you control five or more Cultists,
Cultist Gathering becomes a 6/6 God creature
with indestructible, lifelink, deathtouch, and
"{w/b}{w/b}: All cultists you control populate."
At the beginning of your end step, if this enchantment is not a creature, create a 1/1 black cultist creature token with "{1}, {t}: Target
creature becomes a cultist in addition to its other creature types."
