I do actually want to Commedize our Supply Line next turn before the castle simply because we'd want to do it anyway, might as well take advantage of the bonus. We aren't getting Malifenshmirtz in time for the auction anyway, so. Of course, if some sufficiently important Occult actions show up, we might want to just go ahead with it next turn despite it.
So I think Commedize plus Dino-Farming would be what I prefer in Stewardship, plus what someone suggested with Climate controlled environments ad Greco-roman Terraforming for the max econ boost.
That does mean putting Ludivine within 10DC of the Flubber research though, which people seem terrified of. Campaigning for Flubber might be good just so people don't seem terrified of using one of our best Learning Heroes. We will kind of run out of safe stuff to put her on the moment we get Robo-Doppelgangers and Human Genetics. Are we just not going to use her then? It's a bit of a waste.
However, I actually don't like discussing the turn so early, frankly. Many of our most important actions didn't get their results posted, so it feels quite premature. It's best to start discussing this once all the Interludes are out to me.
