Make your own fun! Normal cards may be easy to come by, but metal cards have a special pizzaz.
You don't even have to bother with suits, so long as you have enough of four different brands of soda or beer.
Use a playing card and a poker chip as stencils to score lines in can-sheet-metal. Tear carefully along the scored lines.
Successive layers of scoring will make your aluminum tear more easily at your marks. Use heavy pressure, and, obviously, do not use a scratchable or dentable surface as support, unless it's a cutting board.
