Clockwork Librarian

{2}, Sacrifice Clockwork Librarian: Search your
library for a Saga, reveal it, and put it into
your hand. Then shuffle your library.
{3}, {t}: Add or remove a lore counter from target Saga, then scry X, where X is the number
of lore counters on that Saga. (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.)
