This card looks surprisingly playable. While it doesn't let you bypass like Inside Job, it can let you approach central servers with ease late game. Especially if you put a little bit of pressure on archives, forcing the Corp to protect it with a piece of ice.

I guess it's a matter of slots like with most other under-powered cards.

You know how Haas-Bioroid: Engineering the Future was so powerful because it gave you a reliable credit every turn. This is roughly the same thing. It says "at the end of your discard phase gain 1 if you have a facedown card in archives" at the end of your DISCARD PHASE, so you could just draw over your hand size, dump a card, and make a profit. This also works a bit like Industrial Genomics: Growing Solutions: you put a trap face down in archives, say Shi.Kyū Breached Dome or Shock! (make sure the trap works in archives, so no Snare!) then leave the runner at a crossroads: either give me money every turn or run archives and suffer the traps. Although, I haven't played this deck enough or seen this get played enough. So mabye i'm stupid and also wrong =)

TL;DR: A draw card for setup decks. Especially potent with setup.

Credit > Draw. Therefore all following analysis assumes that only draw option is chosen:

1. With a normal 4 click turn, there is 3 clicks to install things. Which equates to 3 cards, Diesel gives 3 cards upfront and does not need any further combination.
2. Hyperdriver turn, 6 clicks to install things. 6 cards, quite good.
3. Simulchip, Self-modifying Code, Street Peddler, Gachapon can all trigger this for an explosive turn.

In conclusion, it's good for setup decks where they install a lot. It's almost a good as a 4th Diesel there, and can be more. Also, just like other draw events like Diesel, this card is at odds with the Professional Contacts engine.

There are two different (and non-exclusive) ways of looking at Cyberdex Sandbox.

The first is as a piece of tech hedging against virus decks. It gives you a free purge on score and repays the credit cost of the score (but not the clicks!), and it makes future purges forced by threats such as Medium less of an economic setback by compensating you with 4. Compared to Cyberdex Virus Suite, the existing neutral standard for virus hate, you get a more reliable and repeatable upgraded purge ability, and your tech card takes up an agenda slot, which is generally better to make sure you get enough space for plenty of ICE, economy, and other utility cards. While Virus Suite charges you 3 and a for a manual purge, it is also an ambush which can shut off Archives from Datasucker or Aumakua counter farming. The fact that you can purge with a pre-installed CVS also makes it a shoe-in against Clot if that card is likely to hamper your fast advance plans.

The second is as an economy agenda that immediately somewhat compensates you for scoring it, and then offers a slight improvement over spending on basic "take a credit" actions. This isn't fantastic, but I think it does compare favourably to the now-rotated Gila Hands Arcology; the immediate buy-back of 4 makes scoring much less painful, although it probably takes two or three more manual purges to actually be economical. Not great though when Corporate Sales Team pays out 10 without demanding any additional clicks, and it pays that out relatively quickly too. If you just want cash, Corporate Sales Team is virtually always better, and it is even the same advancement requirement to points ratio.

So, if you're going to play Cyberdex Sandbox, you have to want the purge and not just the credits. If you're playing a lot of fast advance, Cyberdex Virus Suite is still going to be your first choice of virus hate, but Cyberdex Sandbox can carry tempo and glacier decks further by offering repeated economical purges. Of course, if Freedom Khumalo: Crypto-Anarchist somehow becomes the runner meta you could play both, and if you don't need virus hate at all, then you don't need either.

One final note is that Cyberdex Sandbox, over all other virus hate, actually self-synergises and rewards you for purging through other card effects, such as Macrophage and Reverse Infection. You score a second Sandox and now you get 8 and you can spend for 8 again whenever you want! Maybe you do want to play both Cyberdex Sandbox and CVS after all! While this sounds like a huge deal and a powerful way of playing this card, I actually think this is at best a fun gimmick, and at worst an outright trap. It is not easy for most corp decks to stomach multiple 2/4 agendas, and there are plenty of others you can score twice (like Nisei MK II or over-advanced Project Atlas) that can straight up win the game and don't demand going all-in on virus hate that will be largely dead in some matchups or until you score your vulnerable 2/4. All Nisei MK II needs to support it is some good taxing ice and a functional economy, and unlike Reverse Infection, you were probably playing those anyway.

At first view, this card seems like the poor man R&D Interface. Half the cost AND it is a program, not an hardware. Those are drawback right?

But there are synergies to get with this. First, like any installable card that has a limited use, it is a prime candidate to become the target of Aesop's Pawnshop. Second, being a program, this is tutorable by Self-modifying Code and Customized Secretary.

So, is it better than The Maker's Eye or R&D Interface? Short answers : no, but it has uses. It is equivalent to The Maker's Eye in term of multiaccess. The only advantage it has over The Maker's Eye is that it can be fed to Aesop's Pawnshop (for a net 1 cred gain) and it would not be stopped by Crisium Grid (good thing). But it has less tempo than The Maker's Eye.

In specific type of deck, like those using Customized Secretary and deck using Aesop's Pawnshop, it can be worth it. Making every cards used give you a positive cred gain is nice.

The art is very nice, once you notice it among the saturated colors. Nice quote also.

I just don't understand why it is 3 influences, when R&D Interface is 2.
