Not very good. Unless you're letting multiple subroutines fire -- which probably means you're losing -- this is worse than Dirty Laundry and harder to deploy. Dirty Laundry pays you to take safe runs you wanted to make anyway, which is great. Bravado pays you to run on ice when they probably can't rez it (or when you can beat it), another great time to run. RCS pays you to risk runs where you DON'T expect to be able to break the ice, which is probably the worst time to be running. It also doesn't pay enough that I'd want to lean into runs where I expect subroutines might fire. For this card to be playable, you have to expect unusually low-impact subroutines, which are not very common. RCS matches up well against a handful of rezzed ice like IP Block, possibly Mausolus, possibly Border Control, and a bankrupt run on an Afshar. It fares poorly against unknown ice. But... at the point where +$2 and 1-2 card draws would be most meaningful (early game), most ice will be unknown and you're the least able to deal with an ice if it turns out to be a sucker-punch like Fairchild 3 or Ansel or Saisentan. :-/
Separately, the card's effect is poorly explained in its text. There's a lot of room for confusion on whether RCS is supposed to give you $3 "for each hosted counter" or just a flat $3 once. Unfortunately, it's just a single $3, which makes the card quite bad. (In Standard, at least. In Startup ice are significantly less dangerous).
What about Bankhar?
If you have Bankhar out, your two-card combo can KIND OF break even getting through the first ice in a run by risking a lot of net damage and draws. But using RCS (a run event) means you're NOT using a run event like Chastushka, so your upside on the run is rather limited. Bankhar is risky/painful and I wouldn't want to use him unless the run has a lot of upside. PS: whether or not you're using RCS, on a Bankhar run you still might need to break the first ice because several ice can deal 5-6 net damage (Anansi, Endless EULA, or a fresh Envelopment). Taking 6 net damage now so you can draw 6 cards later is either fatal or the worst Moshing of all time.
