A high initial cost, but zero spent after that. You cannot up the strength, which means you need to pair it with some means of strength-boosting like The Personal Touch or Dinosaurus to get past stronger stuff. Other options are with Datasucker, Ice Carver, or a combo with Parasite.
I love to pair this with Rielle "Kit" Peddler: Transhuman and Dinosaurus. Get past all but the staunchest code gates and force the Corp to go deep quickly to negate her ability. With a Paintbrush, this card is a monster.
