I reviewed the code and noticed an issue with the visibility of empty_deck. I plan to investigate and resolve it when I have more time.

Fixed!

I think this looks good - after looking through our back stack management though, I'm curious if we are missing a CLEAR_TOP on the Intent for the reviewer though

Otherwise (that is: the bulk of the PR): looks good

Fantastic, I think this looks pretty good and from the video it looks pretty good to me

If you are curious at all - and I mention it because I have seen you do related work so I think you might be interested? - you might look at #17073 to consolidate our usage of these flags...
