Important note: It says ACCESS, not STEAL. That makes it a counter to NAPD Contract, Fetal AI, and Red Herrings as it provides the credits required to steal (and more!) upon accessing. It also provides a consolation prize for Agendas that can end up yielding nothing on access, such as The Future Perfect, Domestic Sleepers, and 15 Minutes. Against corps that are over-reliant on Agendas like these, this card offers powerful econ in a situation where the corp might not be as worried as usual about you accessing.
Specific interactions aside, sometimes you know you can get into a server and the corp doesn't. First click this, second click D4v1d can be extremely unpleasant, even if you have to burn off all the counters to break that outer Curtain Wall. To say nothing of Stimhack...Anarchs generally have a few tools for scoring an access that really should have been out of reach, and this card lets you capitalize on them. It's easy to categorize this card as win more, but it can also be used to turn a temporary advantage into a more permanent one.
