Espionage

Create a colorless Secret artifact token with
"{2},{t}, Sacrifice this artifact: Draw a card, then
discard a card."
Look at the top three cards of a target opponents library. Exile one of them face down and put the
rest back in any order. For as long as you control
a Secret, you may look at the exiled card, you
may cast it and you may spend mana as though
it were mana of any type to cast that spell.
