At the beginning of your upkeep, exile an instant or sorcery card at random from your graveyard. You may cast it this turn. If a spell cast this way would be put into your graveyard, exile it instead.
Say I have a Bonecrusher Giant in my graveyard, will Scrollwielder attempt to exile the "Stomp" part of the card, and if i then cast it will I then put Bonecrusher Giant in the adventure zone?
