There's something interesting in the we get our first advanceable Upgrade in this pack with Defense Construct. It suffers from the same 0-trash-cost disease that the other advanceable traps do, but it's still an interesting space to play in. For a janky example, you can install a Snare, install Defense Construct, and advance the Construct once. Now the Snare! looks like a defensive upgrade, and the Construct looks like an agenda. Once they're in, they take damage and a tag, and you get back a facedown card of your choice. It's a damn shame it's relagated to facedown cards, though. Still though, it feels like there might be some really good use of the fact it's advanceable, yet not an asset or agenda. I'm having trouble thinking of a realistic best-case scenario for it at the moment, but I sure hope someone figures something out.
