The Oracle has those rules abstracted into the drawing mechanic, though it could be down to group preferences. If you played with the expansion rules and an Oracle the game wouldn't suddenly catch fire, but it would make the tone a lot lighter and give players a very strong edge.

Figured as much, and would have played without the extra expansion rules if using the Oracle (and honestly the Oracle is the more personally tempting mode even for non-solo play, for me), but I figured I might as well ask after intent
Edit to add, because I forgot: Thank you! Also this looks excellent, as does Helion, Our Home
