Rogue's Admittance

{t}:Add {c}.
Infiltrate(Whenever you play an instant or sorcery spell, target opponent reveals a card at random from his or her library. You may choose to put that card on the top or bottom of its owner's library.)
Many spies, rogue's, and thieves have passed through these doors, with knowledge and artifacts to sell to whomever is willing to pay the highest price on the streets.
