No, copper and bronze are different. By copper, they probably meant the darker ones, and bronze are the lighter ones.
Maybe, but both of those colors I would say are closer to the Brown variety of colors rather than Silver/White.It'd be nice to get some clarification from SM on this. =]
There is a silver launcher isn't there? I heard it had Foxbat's monster form on it. Anyway Copper is probably the older cards since if you look at them their color is a bit different than our Bronze cards...
No.
