This is one of those cards that prompted a confused "Huh?" response on release. However, with the advent of Spark Agency, this might start seeing some play. As the other review mentions, this works well with Personal Workshop decks, as long as you don't mind floating at or near 0 credits for most of the game.
But there are a few problems with this, and they are quite substantial. For starters, it is pointless to try and use this with some other terribly useful cards in the current meta, like New Angeles City Hall. Even with burst econ, you usually don't want to stay low in credits, as a wise corp will know you either have that Stimhack in your hand, or you can't contest the server, and they can just install an asset or upgrade in their scoring server to test the waters.
If it weren't unique, I could see this being pretty powerful, but as it is, you're probably better off with other drip econ, namely Underworld Contact or even Data Folding. There are just too many other, better options out there, and while Spark Agency is really catching on, I don't think it's enough to warrant inclusion of this in your deck.
