One thing I like about Netrunner over MTG is how you can just click for credits and cards in the former, while the latter you risk getting mana screwed.
In early Android Netrunner, clicking for credits/cards was not much less efficient than cards that generated credits/cards, but as cards were printed that were more and more efficient at generating credits and card draw, luck slowly became a greater factor, and the possibility for getting something like a weak form of "mana screwed" may become more prevalent (unless sufficient options and tutors for those options are available).
Because cards are becoming more efficient, I'm afraid that the Runner game will become more reliant on drawing specific high efficiency cards, and even if you can still click for credits/cards, the gulf will become so significant in efficiency that some games may become decided just by how many of some card you draw.
As Corps inch further in their advantage over runners, drawing multiple Account Siphons becomes more relevant, for example. Runner decks become more of high risk, low consistency, unless sufficient tutors are printed or alternate options become available.
Corps could (especially in the early days) get screwed by being agenda flooded (now mitigated somewhat significantly by Jackson Howard), but now Runners also can get screwed by not drawing their high power cards. Runners used to be able to build for consistency, but now it is becoming more apparent to me that they need to incorporate high risk, high reward, low consistency cards if they hope to keep up with Corps.
Hence, e.g., the vanishing of Professional Contacts in decks and the imperative to run 2-3 Account Siphon out-of-faction.
Maybe I'm dramatizing a bit, but I still think there is an apparent trend.
