Once during each of your turns, you may cast an instant or sorcery spell from your graveyard by sacrificing a creature in addition to paying its other costs. If a spell cast this way would be put into your graveyard, exile it instead.
If you cast an Adventure spell from your graveyard this way, it's exiled as it resolves with the replacement effect created by the Adventure rules and you may cast the creature card from exile later.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
