This feels like a pretty bad card. But let's look at the individual aspects of this card before making judgment calls.
It's an upgrade. That's a good thing as it can be installed in any server.
At 3 influence it's unlikely to see play outside of HB.
It costs 2 to res. That's decent.
The trash cost is 0, so any runner will trash this unless you have some other form of protection (e.g. NBN: Controlling the Message).
It requires trashing to activate. That kinda sucks. But it doesn't require a click so you can do it during a run.
The trash ability only fires during a run on archives. Combined with a 0 trash cost this means you need to install this on archives as only during a run on archives it's guaranteed to fire.
To actually do something it requires advancement, one click plus a credit per card.
To add to the downers it only works on facedown cards. So recurring used operations is out.
In terms of common inhibitors (Rumor Mill, Employee Strike, Interdiction) it's vulnerable to Interdiction but not Rumor Mill. That's still not great considering Interdiction is a pretty useful card.
Moving to analysis let's look at what it's good for. It's designed to bring facedown cards into HQ (not R&D like Jackson Howard). This allows for broadly two uses: saving cards from being accessed by the runner and using archives as an extension for HQ.
There are two major sources of facedown cards in archives: forced trash (Anarch speciality, Noise: Hacker Extraordinaire in particular) and overflow of cards in HQ. At the high cost for saving cards from archives you really want to use this for your most valuable cards only, that is of course agenda's. Comparing to the current baseline (Jackson) it's quite an investment (4 + 5) whereas Jackson is 1 + 0. Jackson however is also vulnerable to Rumor Mill and will of course cycle soon.
Other alternatives for card saving during a run are:
- Allele Repression - asset, roughly the same pros and cons as Defense Construct except it has a 2 cost and requires you to trash cards as an additional cost.
- Shannon Claire - asset, Rumor Millable, only works on one card, 1 + 0, has alternative ability (draw from bottom of R&D).
None of these are really all that great either. Only Jackson is much better for saving more than one card.
Another use is using archives as extension for HQ. That is, dumping cards you don't need right now and recurring them later. For this use Defense Construct is expensive and alternatives like the unreliable Bryan Stinson, the terminal Friends in High Places and the cheap but limited Archived Memories are probably better, though which one depends on your exact use case.
All in all this feels like one for the binder. There is one caveat to that conclusion however, if FFG adds ways to put counters on cards like Defense Constructs cheaply it could become a moderately useful card in the right deck. Since we're only at pack 1 of Red Sands and FFG likes to spread out combos over multiple packs this is defenitely something to keep in mind.
