All the other reviews are much better than this one I would argue
Anyways; Strength 5, 4 ETR subroutines is rather solid I think, since that ends up being rather expensive. Best case scenario the runner avoids the server for 4 turns waiting for the power counters to run out. Doubtful that would happen anyways.
However, now that Banner is out, you know what happens. Corp pays 5, runner spends 2 to ignore all those subroutines, except for the one trashing the ICE of course.
Anyways what i'm trying to say is, I think there are more solid barrier options, obviously pairs well with Ob Superheavy Logistics: Extract. Export. Excel. but, again as I said, Banner.
