I created a GitHub page paolosaracco.github.io following the instructions and it is published under GitHub Pages.

Now I would like to add to this page the HTML pages of my projects, which are stored in other repositories different from the one where the page is stored. For example, I would like to add this

To this aim, I would prefer

• not to add the projects to GitHub Pages as suggested in this answer or here
• not to clone the whole project repository in the GitHub page repository as suggested here
• not to use the htmlpreview.github.io/ trick as in htmlpreview.github.io/?https://github.com/paolosaracco/MTG-TopRankedDecks/blob/main/MtG_project.html
• not to copy-paste the html file into the paolosaracco.github.io repository (because if I update the project, it will not be updated on paolosaracco.github.io)

Is there a way to, for example, clone the single html file MtG_project.html from the MTG-TopRankedDecks repository to the paolosaracco.github.io one?

Or to directly link to the html page?

Please, notice also that I am relatively new to GitHub and I use it through the browser interface.

I already made all the naive attempts like adding a link to https://paolosaracco.github.io/paolosaracco/MTG-TopRankedDecks/blob/main/MtG_project.html, to https://paolosaracco.github.io/paolosaracco/MTG-TopRankedDecks/MtG_project.html, etc., but I am well aware they will not work if the html file I want is not contained in the same repository as the index.html.
