0 hosted power counters: Reveal Domestic Sleepers from HQ. Repeat until the Runner gets bored and leaves.
Anyway, this can be a nice card for warming up your scoring server. You put it in there, rez an ICE or two in front of it to keep the Runner from trashing it, maybe rez some ICE over centrals or pop up something like a PAD Campaign in an empty server, then score your first Agenda by IAA-ing it and revealing a second copy. Of course, this relies on HAVING two copies already, so it shouldn't be a primary strategy. You can then just trash it to start scoring regularly in that server. As a bonus, if they unexpectedly get into the scoring server they don't even get any points.
It might be possible to ACTUALLY make it a primary strategy by having it occupy your scoring remote and scoring all 7 points this way, but be aware that you'll need beefy HQ protection since you're going to be holding a lot of nice stuff there. Cybernetics Court is probably a good idea in this case.
You don't have to spend every counter on it to activate it; if it has two counters you can spend one to protect a one-pointer, and similarly if it has any number (including zero!) you can spend zero to protect Sleepers.

I know I'm leaving this message 6 years after you posted it but this card triggers itself on rez, so it will always have at least 1 power counter on it, which means you cannot do this trick with Domestic Sleepers.
