Obeus, Master of Secrets

When Obeus, Master of Secrets enters the battlefield, create two colorless Secret artifact
tokens with "{2},{t}, sacrifice this artifact: Draw a
card, then discard a card."
{2}{b}, Sacrifice a Secret: Target player sacrifices a creature.
{2}{u}, Sacrifice a Secret: You may cast an instant
or a sorcery spell from your graveyard. If that
card would be put into your graveyard this turn,
exile it instead.
