Tutor is a term borrowed from Magic the Gathering for a card effect that finds the card you need from your deck. It's not as though Shapers were hurting for program tutors. So, what does Customized Secretary have to offer that the others don't?
The thing that makes Customized Secretary unique is that it could potentially fetch you up to 5 programs. However, this also makes it only a pseudo-tutor since this random sampling of programs may or may not contain the one you need right now. In almost all cases this is inferior to SMC which installs the card you need in any action window, or to Test Run which can fetch programs from the heap as well and pairs nicely with Scavenge.
So, can we find any reason to play this card? Clearly, we need a deck chock-full of programs to get value here. If that were the case, Customized Secretary becomes like Batman's utility belt allowing you to pull out just the tool you need for each job. What charming academic do we know that loves playing lots of programs? None other than The Professor: Keeper of Knowledge. Of course, even in a deck full of program you can easily miss the one you need. Sure, you could Scavenge Customized Secretary to use it again, but there are far better targets. You are already playing the The Professor: Keeper of Programs and Customized Secretary, might as well go full jank and slot Brahman to recycle this. Sahasrara makes it free to install.
Frankly, at time of release, I can't see any reason to slot this other than love of jank. So, throw this binder fodder back where it belongs. Or join me, mild mannered academic by day, digital Batman by night...
