I've been using this ICE a lot lately, and it is sweet! NBN getting 2 great new barriers in consecutive packs is kind of bewildering. The stats on this ICE are great. cheap to rez, high strength, it's everything you want in an ICE. I would most likely compare it to News Hound. Same rez, same strength, trace with conditional ETR. I think News Hound is slightly better because currents are more popular than AI right now and Sentry's with ETR's are rare. Nonetheless, this clamps down on the Baba Yaga bullcrap I've had to deal with for a while, as well as other popular AI's like Faust and Atman.
Pros:
Cheap as dirt
Great strength, Parasite resistant
Trace 3 isn't too shabby
AI encounter is good
3 to break with both Corroder and Clippy
Cons:
Encounter effect is nifty, but blank if they aren't running AI
People are super paranoid about traces lately, so Trace 3 might not be so great
1 Sub is blank if they ignore encounter/beat trace
