Nacardo, the Forked Mind

While you're searching your library, you may pay {2}{b}{g}{u} and exile Nacardo from your library. If
you do, it becomes plotted. (You may cast it as a
sorcery on a later turn without paying its mana cost.)
While you're searching your library, if an instant or sorcery spell caused you to search it, you may exile
a nonland card with mana value less than that
spell's mana value that shares a color with it from
your library. If you do, it becomes plotted. Do this
only once each turn.
