Inspiring Teachings

Draw two cards.
Cascade for instants and sorceries (When you cast
this spell, exile cards from the top of your library until
you exile an instant or sorcery card whose mana
value is less than this spell's mana value. You may
cast that card without paying its mana cost. Then put
all cards exiled this way that weren't cast on the
bottom of your library in a random order.)
