> doesn't make it okay.

In this case it is OK, because this isn't gambling, according to what the manufactures claim, and they go to great lengths to claim that it is not gambling.

If it is not covered under gambling laws, and the manufactures declare that all cards have no monetary value, then I see no problem at all.

> Do you feel that that was wrong of me to do?

No, it is not wrong at all, because the manufactures say that it is not gambling. Therefore this is fair game.
