I want to cast [Dire Fleet Daredevil](http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bDire%20Fleet%20Daredevil%5d) but my opponent has no instants or sorceries in their graveyard.

Am I able to cast it?

The text doesn't read "You **may** exile target instant or sorcery", but it also doesn't require it as an additional cost.
