At first I did not think I would enjoy Gravedigger as much as I do now. It sits as a 1-of in my Noise: Hacker Extraordinaire deck, along with its trusty Paul Bearer Virus Breeding Ground. But when you're solitaire-ing out a few turns or just stalling to sweat out the corp, the mill can be frustrating. In a recent tournament, I would Wyldside up, play out a virus, click a token from Virus Breeding Ground on to Grave-y-boy, and mill a card. I ended up starving corps because they now had to dig for answers while I stuffed everything in the yard. Definitely not a card to rely on, but still strong when planning to mess with the corp's plans.
