Two obvious, notable interactions:
- Ashigaru gains an unmanageable number of subrountines once this is rezzed, but is influence expensive for HB
- IQ becomes incredibly strong & great value if you rez it before using Cybernetics Court to prop up your HQ size
Arguably better than Research Station since its effect is larger & trash cost higher, though you're unlikely to want to defend this whereas RS benefits from your HQ ICE as well. Unless you're comboing with something or negating the downside of Cybernetics Division there's just not enough benefit to increased corp hand size to warrant a deck slot.
(Business First era)
Why not both? Research Station is only one influence. If you're making a deck that abuses high Corp handsize in some way, it's probably worth splashing one or two for reliability.
