As the title says I am looking for some light roughly paper thin metallic sheet material that a magnet can stick to. I am trying to make a Yugioh duel disk that you can actually play on and the current plan is to make the cards be able to stick to magnets so I dont have to awkwardly tuck them in or under stuff.

I did a test run and I was able to make it out of some metal sheets that ended up being the perfect thickness BUT I ran into the issue of the weight which came to 1060g for 55 cards in total. The deck can be played almost just fine provided I dont have to hold it on my arm for any substantial length of time.

For someone not into the know yugioh cards are 59x86mm each and the game is played with usually a min of 40 main deck cards and 15 extra decks cards
