Why are you defining everything so rigorously? It doesn't matter at all whether you do card magic, or sponge ball magic, or disappearing elephant magic (although I wouldn't recommend that for table-hopping), because magic IS NOT ABOUT WHAT TRICKS YOU DO OR PROPS YOU USE.
Apologies for the capitalisation, but I've been reading a lot of magical theory lately.
You are a magician, you are in your very essence magical. The spectators should think that everything you touch could at any moment do something utterly unbelievable and wonderful. Not a single spectator is going to go "he didn't do as many card tricks as I'd hoped" if you are doing your job correctly.
Read some of Eugene Burger's work about the philosophy of magic, and how to make the most out of your performance. He has some articles on his website that are worth reading:
