Miyani, Blessed by the Moon

Whenever an opponent shuffles his or her
library, you may put a +1/+1 counter on Miyani.
Then you may exile the top card of your library.
You may cast the exiled card this turn.
Whenever you shuffle your library, scry 1.
(This effect happens after you're done shuffling.)
As I gazed upon the moon, I was filled with an overwhelming sense of duty. I know not what I must
do, but I follow the moon's ideals. - Miyani
