Faith's Reward

Scry X, where X is your devotion to white.
(To scry X, look at the top X cards of your library,
then put any number of them on the bottom of your
library and the rest on top in any order.)
Draw {x} cards, where {x} is the additional
amount of mana spent to cast this spell.
Faith. It's all about believing. You don't know how
it will happen. But you know it will.
