Alternative to HoochiePapa's Parentdeck-Subdeck Randomisation

[Rumo]

You can use filtered decks. I’ve elaborated here (follow the link to see an image):

Randomize card type shown first, for the same note

That really depends on what you wanto to do with it. If you want to replace your regular study with the random filtered deck, you could do something like [filtered] and set the limits accordingly. Enabling the second filter requires the new scheduler, though. Then you rebuild and review that deck daily. But since I don’t use filtered decks that way, I can’t speak from experience what limitations there might be compared with the regular study.
