A cheap and effective foil to AI breakers. This card is trivial for a Corroder or other fracters to break, but against an Eater or Overmind this card is very taxing. At one influence this can easily splash in any deck that you can't fit a Swordsman into if you are afraid of AI or Parasite. Against a standard program setup, Wall of Static or Eli 1.0 are better barriers.
Also, if you are using Paper Wall for some reason, just use this instead. It costs 2 more but doesn't self-destruct.
