Reverend Mother Mohiam

When Reverend Mother Mohiam enters the battlefield, scry 4.
Whenever another Bene Gesserit you control enters
the battlefield or attacks, draw a card.
—
"Observe her, comrades! This is a Bene Gesserit
Reverend Mother, patient in a patient cause. She
could wait with her sisters -- ninety generations for
the proper combination of genes and environment to
produce the one person their schemes required."
