Relentless Onslaught

You may cast Instants and Sorceries from your graveyard, whenever you cast a card this way, exile it instead.
When Relentless Onslaught enters the battlefield you may search your liberary and/or graveyard for a card named Azura, Mad Fearie, reveal it, and put it into your hand.
The Mad Faerie is getting restless, a sign of war, soon
to follow.
