Be a little careful rezzing this card against Noise: Hacker Extraordinaire, especially on R&D. There is no 'may' clause to the sub, which means the corp has to return an installed card, even if you've bounced his entire rig except for his last Cache.
Hopefully I never make this mistake again, as I was milled hard while my opponent giggled and set up a pile of credits while continuing to access and mill. Did I mention how he milled me constantly? He wanted to make sure I didn't draw another IE to replace this guy with.
It wasn't worth it to bounce a Medium.
Otherwise this card has saved my bacon on many occasions and is a powerful run deterrent to most runners. But screw Nosie.
