Poor Waiver. NBN's very own hand-wiping ICE alongside Komainu and Brainstorm, this little piece of bureaucracy has made shockingly little impact to the NBN ICE suite. This is a shame because it has a lot of things going for it.
Pros
5 strength code gates are always welcome
At a reasonable cost, too! 5 rez is one less than Fairchild 3.0, but you lose 2 subroutines and the bioroid weakness.
Ridiculously high face-check value, can be a devastating setback for a runner holding key pieces in hand
Even if you don't wipe their whole hand, you still get to snoop into the runner's grip and make informed decisions about your next move...
Possibly following up with Salem's Hospitality or a freshly rezzed Ibrahim Salem. A Neural EMP kill is also possible.
Cons
Is a Tracer, which can be invalidated by high link strength
Runner has control over what you trash, may spend only up to their most expensive card, this is mitigated by the fact that you can see their hand still.
Pretty weak to D4v1d, but taxing for other breakers
