I also had the P&P set, and I did think it was quite fun. Very mind-warpy, although I doubt it has the same legs as Yomi it was still definitely fun enough for me to make a post about it all this time later!
I have no idea which Patreon post has the files, sorry. If you google for it, you can find the Google Doc for the rulebook easily enough, but as for the cards... No idea.
To be fair, even when it was still being updated, so was Fantasy Strike, so it's been basically a footnote for all it's life.
