Join the Cult of Bijhipar

When this faction enters the battlefield, and
whenever a creature card enters the battlefield
from anywhere besides your hand, put a rank
counter on this faction.
At the beginning of your upkeep, you may
sacrifice a Human. If you do, create a 3/2 black
Horror creature token. If you don't, create a 1/1
white Human creature token.
As long as this faction has four or more rank
counters on it, Horrors you control have menace, and enter the battlefield with two +1/+1 counters.
