The Moss Prophet

Changeling
As Moss Prophet enters, choose a creature type.
You may look at the top card of your library
any time.
You may cast creature spells of the chosen type
from the top of your library.

Light is life, beaming, pure, brilliant. To stifle that light is to suppress nature. Nature suppressed distorts, plagues us. Embrace light! Achieve union!
– Moss Prophet
