I think people are underselling this card. I agree that it doesn't work in most decks, such as Sol, but I think this card is pretty scary in one deck: Spark Agency: Worldswide Reach.
Let's get the disadvantage right out of the way: Your operations cost 1 more to play. This seems daunting, but there ARE ways to dance around the weakness. At first glance it seems to be, "Don't play operations at all" but I think this is a mistake. I think a better strategy is to cherry-pick your operations for maximum effect.
Operations You Don't Want
Raw Economy: Hedge Fund, IPO, Beanstalk Royalties, etc. If you use those with this current, you're doing it wrong. This makes your profit one less from all of these cards, making them way less efficient. Running something like Biased Reporting might be okay because it has a huge potential profit, but otherwise, you should steer clear from these.
Trace Cards: Hard-Hitting News, SEA Source, Hellion Beta Test, et al. The basic formula for MOST trace cards is trace=cost+1. With RB out, it becomes trace=cost. This pretty much sucks unless you have Primary Transmission Dish or the runner is so down on money that it doesn't matter anyway.
With about 50% of regular NBN operations disqualified, what's left?
Operations You Do want
Gotcha cards: Basically, operations that don't rely on an economic advantage to make full use of, or use efficiently, their effect. Hunter Seeker, Salem's Hospitality, Ad Blitz, Casting Call, etc. Sure, paying an extra credit to use your tech is kind of bad, but using Salem's Hospitality for 3 credits instead of 2 doesn't significantly affect the card in any terms of its ability.
So, what do you fill up your deck with now that you have 12+ slots open?
Well, if you're playing Spark Agency: Worldswide Reach, you fill up on as many Advertisements as you can. PAD Campaigns, Launch Campaigns, and CPC Generators will become your economy while actively draining theirs. Imagine an opening turn consisting of an Ad, CPC Generator, and Rolling Brownout. You rez one of them on your turn, then the next on the runner's. In order to play a measly Sure Gamble, the runner will have to click for credits 3 times and play it on their fourth click, while probably you gain a credit from CPC Generator. This is pretty great. If you want to go the FA root, you can trade your Biotics for Calibration Testings.
Overall, I think this current fils a great niche in Spark, even if it might not make it into other decks.
