This is my attempt on Spark and it works quite well.
This is a NBN Rush/Glacier deck, which utilizes Spark's ability to mess with the board state and help you score your agendas. The whole point is making money and/or keeping the runner poor to have enough time building up your scoring remote with Ash, Caprice, optionally a SSCG and some big ICE.
And this happens earlier then expected most of the time.
MVP goes to Product Placement. It's just so versatile. Use it to "protect" your assets (does the runner really want to pay 6 and give me 2 for trashing a PAD?), keep it in hand as Legwork "counter" or install it on RnD/HQ to see the runner cry while he runs into the Caprice with only 1 Credits left because you rezzed it and won the psy game automatically.
Ad Blitz is pretty cool too with so many targets. The runner parasites your Pop-Ups? Get them back for x creds and also steal the runner some money.
The rest is pretty straight forward. It does quite well against most match ups because it outmoneys most of them and still is fast enough to win a race against heavy setup decks.
Messing with Kate is so much fun, but you have to be fast enough to not let her build up the rig.
Noise could be pretty hardcore because there's nothing to punish the runner, but that's the thing with every non-kill deck.
I don't think this ID will be Tier 1 or even 2 any time soon, but if you actually want to have fun while playing Netrunner, try it :) And tell me how it did for you.
Improvements for the future:
Maybe a slightly different ice choice. I think a bigger barrier could come in handy.
