Spot the Prey is not a very good card. First off, I'd like to say that expose is a fairly underutilized mechanic. It is great to have if just to deal with Mushin No Shin, but it can be hard to find room in your deck and so, many times, runners have little or no means to expose cards. If you do find room to include an expose card or two, though, I would suggest something else.
Lets compare to Infiltration, an influence free neutral card that has been around from the beginning. In most cases, Infiltration is a lot better than Spot the Prey. Infiltration is free to use. StP costs 2 , which is way too much for what you are getting. Infiltration can expose ICE while StP cannot. In general you want to expose non-ICE cards, but perhaps in a rare case you want to expose a piece of ICE. Infiltration gives you that option. Nothing worth exposing? Infiltration gives you the option to gain 2 instead. This isn't game changing, but I'm sure we've all had times where we were short 1 when we needed it.
Now the one area where StP beats Infiltration is in click compression, but only sometimes. If you use StP on a newly Mushin'ed card and see it is an agenda, then you can go grab it with the same click. This click compression costs you 2 though, not always worth it. And there are times when you won't want to make a run after. Say the Corp has four servers. The three central servers are protected by ICE that you aren't currently equipped to deal with. The new server contains a triple-advance Junebug. In this case, you'll just need to run at the Junebug and jack out. You didn't get any benefit from the run component of the card. Now it is worth noting that you don't have to run at the server with the exposed card. You may choose to run at R&D for an access after the exposed card turned out to be a trap.
All in all though, I don't expect to see this played. If you find yourself wanting to include some expose in your deck, there are better choices. Try Infiltration, Drive By, or even Lemuria Codecracker.
I would have totally considered this for my Public Terminals deck, but it's not a run event.— Raiddinn
I’m doing my thing and catching up on card pools that I missed after quorum.— Kingstontolondontown
The fact that this card isn’t even typified as Event: Run is. Just... shameful.— Kingstontolondontown
It might have a degree of utility in a Ken deck with Public Terminal as noted above. The fact that it isn’t qualified as such makes this so useless and costly.— Kingstontolondontown
