This card's existence and complete absence in play shows that Netrunner has come a long way in diversity. A strange card from the start, with a choice of two effects, neither fantasic. The 2 payout is on par with Armitage Codebusting in the base set, but only works once. Compared to any runner economy cards today, this has no place as a single use event for such a paltry gain.
The second effect, card exposure, has not seen much play outside of Criminal decks with Blackguard. Knowing what you are running for beforehand is a good effect, but it hasn't seen many cards since the effect is pretty quickly replaced by experience. Outside of Jinteki shell games, not much the corporation can do will require exposure to run on. After playing enough games on both sides, a runner can get a grasp for what cards should be in a corporation's deck, and depending on how well protected a server, should be able to estimate what type of card is installed.
The best method of card exposure is still a well-planned run. However, for when you just HAVE to know if the installed card is a Snare or a Future Perfect, remember that this card exists.
