This is one of the most taxing ice in the game, combined with a hard end the run. That is rare enough that I would tell new players to start with this card when building corp decks of any faction.
Yes, it's Femme Fatale target #1, but put another way, it clears a Fem off the table while probably still ending the run at least once.
This costs Torch, the strongest code gate breaker in the game, 5 every time. It almost demands a Fem or Parasite + Datasuckers if the runner ever wants to see that server again. It is worth clicking for credits to pay for.
This card is very, very good.
