Infinite drip econ has always been rare in Netrunner, and for good reason, as it is a very powerful engine. Data Folding is one of the last of these cards, now that the very popular mr Phones was rotated by Nisei. But soon, we are getting Rezeki, and I am very excited for it.
Unlike the two aforementioned cards, Rezeki has no condition attached to it. You install it, and every turn from now on you will get a credit. However, as this is a program, you have MU to consider. Can you afford to have several of these installed, as well as your ice breakers? In that sense this card has anti-synergy with Data Folding, as the stipulation of having 2 spare MU gets considerably harder with several copies of Rezeki installed.
That being said, there are plenty of ways around this problem. Sunny doesn't care about the MU at all, since her cloud breakers don't use any. Install Security Nexus and you can happily have 3 Data Folding and 3 Rezeki dripping. Adam with Brain Chip can also profit from this set up. Good thing Rezeki is only 1 influence! But shapers themselves also have plenty of answers!.
Dump them on a Leprechaun, install a couple of Cyberdelia, a 2-MU console... The credits must flow!
All in all, I think this is an extremely good card that will see a ton of play, both in and out of faction. Also, I must admit I have never been a huge fan of abstract designs. But big shout-out to Jakuza, for this beautiful card art.
