Extraordinarily powerful. This is arguably a straight improvement on Caprice Nisei, a legendarily effective card. Anoetic Void locks down a server forever with the slightest bit of support. 3 Aikis? Unrunnable, unless you are so far ahead you can spend 10+ credits and a click to cause the corp to lose 2 credits and 2 cards of his choice. 2 cheap ice and a Mamegarm? Unrunnable. Surveyor + anything? Ghastly. A Mamegarm + any ice? Arguable. Board states this uncontestable shouldn't be this cheap.
This card design is viciously oppressive.
- This never should been able to fire more than once a turn
- The corp discarding 2 cards of his choice is not actually forward progress for the runner, nor is it a serious cost for the corp*. If the corp had to do something like trash an ice in the server to trigger Anoetic Void, at least the runner is weakening the server for a later run.
- This card should fire BEFORE Mamegarm.
Effective counterplay: Not much. If you see this card you just have to hammer every other server because the Anoetic Void server will never be touchable. Or you need to start slotting Political Operative. Unless AV is itself on HQ, in which case your counter to Anoetic Void is hard-countered by Anoetic Void. :-)
*Previously, hard "end the run" effects have been mostly limited to a top-tier agenda and a top-tier trashable ice, both of which can only be used once. In comparison to that, spending 2 and trashing 2 of your cards from HQ for a repeatable ability is MUCH lighter in cost.
