Rhivonia, Favored Supplicant

As long as it's not your turn, each nonland
card you own that isn't on the battlefield has
miracle. The miracle cost is equal to its mana
cost reduced by {2}. (You may cast a card for its
miracle cost when you draw it if it's the first card
you drew this turn.)
Whenever you put one or more cards on the
bottom of your library as you scry, investigate.
