Killed two runners with it, hit a third with one but wasn't counting cards and forgot he had four cards in his hand still. Got killed by one once, got hit by one to wipe my hand but didn't kill.

How about everyone else?

Never - I didn't lose a game as Runner all day, although I did take out 3 Runners with it.

Once. Wasn't even tagged. He tagged me for his first action, then hit me with two scorched earth. I was sitting on 4 cards in my hand when it happened. I was a little irritated. Mainly cuz my Weyland didn't even have the card. >.<

Lost to it once killed with it twice.

I wasn't playing it and never got hit by it (I did flatline to a 3-token Junebug, though.)

I had it in hand a few times but the one flatline I got came from the agenda, not it. Looking back on it, I realized I shouldn't have been 'saving' it for the win the times that I did. Emptying the Runner's hand would almost assuredly have had enough benefits to justify playing it; I just got greedy, I guess.
