Sorcery — Adventure
Search your library for up to three cards and
exile them facedown, then shuffle your library.
(Then exile this card. You may cast the creature later
from exile.)
You may cast up to one facedown instant or
sorcery spell you own in exile each turn. If a spell
cast this way would go to the graveyard, exile it
instead.
