In my multideck you can play Mu: https://diymultideck.mauri.app/games/mu-and-more-revised-edi...

Basically, you write the point values in the card and use numbers 0-11 where 1=2 and 8=9 (1s and 7s in original game). My cards are made out of plastic, so they don't break. And you get the bonus of being able to play many more games. ^o^
