It's worth noting that this card has a peculiar interaction with Accelerated Beta Test, as per the FAQ of the Rules Clarifications. The ruling reads,
"If the Corp uses the ability on The Foundry during the resolution of an Accelerated Beta Test, what happens?
Each piece of ice is installed and rezzed one at a time. So the Corp installs the first piece of ice and then uses The Foundry to search R&D for another copy. This results in shuffling the other two looked at cards into R&D (they never actually leave R&D), preventing them from being installed or trashed."
This ruling, however, isn't entirely a set back. If anything, it removes most of the risk from firing Accelerated Beta Test. For example, imagine you see 1 ice, 2 agendas from ABT. Instead of being forced to trash those agendas (and possibly waste 2 Jackson slots), you can install the ice, fire off the Foundry, and the 2 agendas go back into R&D.
On the other side of the spectrum, if you see 3 ice, using the Foundry's ability is optional, so you may as well decline the use of the Foundry's ability for some free ice.
When you have a mix from ABT (like 2 ice, 1 agenda), the Foundry gives you options. It allows you to weigh the value of the agenda (or asset, operation, so on) versus playing both ice or only 1.
I think this interaction alone makes The Foundry interesting and more compelling, especially considering how often ABT is run in HB decks.
