Spectral Mentor

Flying
When Spectral Mentor enters the battlefield,
look at the top three cards of your library. You
may put an instant, sorcery, or artifact card from
among them into your hand. Put the rest on the
bottom of your library in any order.
"Magic may have faded from this world, but it is not
gone entirely. That is your first lesson, young one."
— Viator, to Iulia
