Heh. I noticed that trick a little bit back. With a Guild, a decent-sized province (like, for instance, my capital in Bellam), and a bit of investment in Construction, it's quite achievable. I finally, regretfully, dropped the idea - I figured it'd cause my Stability to drop, since such abuse of my positions and the luxury/grandiosity of a huge Court would lead to resentment, corruption, and waste within my domain. I'm still kicking around some ideas in my head for appropriate flavor/color that would justify a regular, though infrequent, use of the action, though.
Do note, though, Niels, that the Finance action becomes much more difficult with each use in the same turn. At most you might be able to swing two "guaranteed" uses per season, probably only one - though that would still be of real value.
