Mistmaster Goliath

Cascade for Samurai (When you cast this spell,
exile cards from the top of your library until you exile
a nonland Samurai card whose mana value is less
than this spell's mana value. You may cast that card
without paying its mana cost if the resulting spell's
mana value is less than this spell's mana value.
Then put all cards exiled this way that weren't cast
on the bottom of your library in a random order.)
