Can you use Replicator to trigger a shuffle when you install the last copy of a piece of hardware from your deck?
Text of Replicator:
Whenever you install a piece of hardware (including Replicator), you may search your stack for another copy of that hardware, reveal it, and add it your grip. Shuffle your stack.
My interpretation: the thing it allows you to do (“you may search your stack for another copy…”) is not conditional on there being a valid target in your stack. Per the FAQ, you shuffle (with no other effects) if you are unable to resolve the search.
It was suggested that since there are no valid targets for the search, you shouldn’t be allowed to do it (no change in game state),
