There is a year coming up where I’m unsure of whether or not saturn would act as a co-ruler. It falls right on the cusp of the house of the sign that rules the AC. Same degree.
There’s also a year where Saturn is in the first house of an SR. When Saturn last co-ruled my SR, the year was pretty terrible. I recall it as the worst year of my life, except from last year. Last year was just hectic and stressful and unstable though. It was ruled by Jupiter, oddly enough. A few massive extremely positive things happened. But Jupiter the last couple of years as an SR ruler has acted as a trigger for court dealings, due to my natural placements and transits.
