Jyllia, Wisdom-seeker

At the beginning of your end step, if no creature
named Sharu, Jyllia's Raven is in play, create a
1/1 legendary blue and black Spirit Bird creature
token with flying with that name.
At the beginning of your upkeep you may
sacrifice a creature named Sharu, Jyllia's Raven.
If you do, look at the top card of each opponent's
library, then scry 1 and then draw a card.
