Noise's ability contains one of the rarest and most powerful effects in all of Netrunner: the ability to FORCE the Corp to do something. We have forced de-rez cards and some rare forced trash effects, but Noise is in a league of his own. His ability alone forces the Corp to build a certain way; if you don't have Jackson Howard in your deck, you had better have a plan for your archives protection.
There is almost no downside to his ability. Putting a Cyberdex Suite in the trash could lead to some bad times (heh), but other than the nightmare matchup with IG, trashing Corp cards is just a solid move. He's very versatile and can be horrific to deal with.
