I got a quick fix from fjortisar over at reddit in case anybody else needs it.
You can either:
1) Make a symlink of the sfml-audio and sfml-system 2.4 libraries and run the game. I don't think I did that properly so idk if it works.
2) Download the packages from official Ubuntu site here
(substitute system for audio, or just search it up to also get the sfml-system 2.3 library), and extract the .so files to /usr/lib (I think /lib would work too, just saying what I did) then run sudo ldconfig. After that double-clicking on ygopro brings it up :)
Edit: code to make the symlinks, though it didn't work for me but I think I had gotten the package name wrong.
ln -s /usr/lib/x86_64-linux-gnu/libsfml-audio.so.2.4 /usr/lib/x86_64-linux-gnu/libsfml-audio.so.2.3.2
ln -s /usr/lib/x86_64-linux-gnu/libsfml-system.so.2.4 /usr/lib/x86_64-linux-gnu/libsfml-system.so.2.3.2
ln -s /usr/lib/x86_64-linux-gnu/libsfml-system.so.2.4 /usr/lib/x86_64-linux-gnu/libsfml-system2.3v5
Should work, based on the file names of the packages I downloaded
