This is very cool, I'm a big fan of dice tables so this really plays to my tastes! It is a little difficult to use in a PDF reader though, a problem I've also had with the official pamphlets. Since there is so little white space remaining increasing font size isn't an option so I would consider some other fonts. It is also possible it is the shade of purple used for the background that makes it tricky to read, since I did not notice any issue with the black background parts of the document.
EDIT: Addition of some page numbers might also be a good low-effort addition. These might not look as cool as the pamphlet does right now so maybe publishing a new PDF with page numbers added is an idea if you don't want to sacrifice aesthetics
