Entreating Devotee

Tap any number of Cleric creatures you
control: search your library for an Angel card
with converted Mana cost X, where X is one
less than the number of creatures tapped
this way, and put it into the battlefield.
A deck can have any number of cards named Entreating Devotee.
The meek, in great enough numbers, can bid the very
skies to open and dispel the shadows.
