Many opponents in OCTGN tilt and leave the table after 1-2 Vamps and even curse me about it. Other's just concede the game. Any rich runner should include this card in his deck if he has spare influence, it works wonders against most corporations that are not asset-dependent. If they ARE cashing on assets, trash everything before vamping (if it doesn't kill the tempo).
In my opinion, this card is even better than Account Siphon and you can even keep the single tag, till next turn. How can the corp punish you with 0?
Funny thing is that they made this card red, as Anarchs are typically the most poor of all runners =)
P.S: People, try to be gracious players. You get Vamped or Siphoned 2-3 times or even more, take it like a man. It's part of the game which purpose is to have fun.
