This ice is quite taxing until the runner decides to just float tags. Works really well for central protection in the tagging archetype. I want you to float tags, you don't want to deal with this on encounter so you want to float tags. Just don't get Mindscaped or go Psycho.

The cost is hefty but it's better than Cloud Eater where you have to rerez it every time you want its cool effect. One stolen or scored Send a Message will do the trick. Sucks to get emergency shutdown however.
