I thought it looked a little daunting on reading the preamble - but the title of the puzzle give a good clue to what the the theme was likely to be.
I think the 'remnants matching extra words' was a little misleading, as was the use of the term 'couplets'.
Also, not sure that the 'practitioner' used any of the methods in the puzzle. Or that the shape of that person's name in the grid was symbolic. Was it, do you think?
Apart from that, I loved it. And I still haven't got 38.
