Does one have to force the same card everytime that trick is done?

If you can't answer without reveal I understand, but I like the trick and if it can be a different card I'm sold. If not it is a no-go for me because I would use it in my strolling and would not have access to the same card over and over. Any help would be appreciated as I would like to purchase if it is able to be done with different cards and reset for a different card each time.

Thanks in advance,

ps: just got home from a Nathan Kranzo lecture...Really good stuff.

Probably shouldn't respond because I am not positive but it looks similar in theme to Pixel. There is obviously some different stuff going on between the two but I think they share enough of the methodology that it could be done with a different card every time. Pixel can at least.
