Well you couldn't be talking to a better person :). I actually play a bunch of video games, and am also a huge MTG fan. I make Youtube content and stream myself playing video games. I and a bunch of other advocates are pushing developers to make their games more accessible. Many aren't accessible, but more and more are getting there.
$1 a playlist of video games clips I've taken). I also have [videos on how I play MTG]9https://www.youtube.com/c/BlindMTG) and strategies I use to remember the board, so maybe he would find them useful? Hope some of this helps and feel free to reach out with any questions.
