This is the counter to a lot of NBN ices, and some other ices also. If you play AI breaker, it is almost a prerequisite, to prevent you from getting a tag everytime you encounter IP Block (which is quite prevalent in the Q2 2023 meta).
For Apex, it is also a simple way to get 3 cards facedown on the board fast. In theory, you could also powerup Aesop's Pawnshop with it, but you would normally be better off with Harbinger for that. It will trigger Reaver and Wasteland, so it is beneficial.
It is important to remind yourself that this will not prevent Anansi or Mirāju abilities.
Here are the on encounter effect that can be prevented with Hunting Grounds (12 NBN, 1 HB, 2 Jinteki, 3 Weyland ices).
Those encounter effect are useless to prevent.
If you expect to encounter NBN often, this card it worth it. All for the very low cost of one influence (and 2). For Apex, you'll want it to help you power you other Apex cards, as a contingency card.
Among the Apex cards, it is the one that seems to have the least relation between the name, effect and art, but you can still see the connection, especially with the nice piece of lore coming with the card. A good design.
