Dhegdheer seems like a good substitute for Akametsu Mem Chip. The disadvantage is that it works best when you get this out before a larger program, although you could host any program on it (e.g., icebreaker) and save money down the road. But I think it would work best for hosting programs that are repeatedly installed (e.g., Chameleon) or only temporarily installed until used/removed (Cache, Hyperdriver).
This could play a good supplemental role for economy engines using Cache + Aesop’s as an alternative to Scheherazade (I never know how to spell that card off the top of my head) without costing influence, with the downside that it can only host one at a time.
I have toyed around with a Shaper “toolbox” style deck using all sorts of utility programs for support, and running a full rig of icebreakers + 3 Leprechauns with Paricia, Hyperdriver, Misdirection, Magnum Opus, and programs like Sahasrara. In those types of decks, I think Leprechaun is subjectively better because it gives you more potential MU with fewer deck slots. However, Dhegdheer could find a good home in a “toolbox lite” rig running icebreakers, MOpus, and a few utility programs.
