I skimmed briefly through old comments of yours around early 2018 and didn't see any mention of card usage not being supported on Game Courier. Unless it was another editor, I might have concluded card usage was not supported on my own, since I recall I didn't see any card usage CV presets that clearly worked (there's just 2, one a not too proper-looking CV preset [of the cards type?!] that may work) listed on the Main CVP Alphabetical Index back in the early days for me on CVP site - it seemed there were card usage CVs' rules pages in healthy numbers to me, though.
Any proper-looking dice chess CV with a preset (edit: i.e. just Vegas Fun Chess, of the 2 CVs with presets) had logs that had just shown error message pages when I attempted to view them back then, I recall.
Hmmm...
