There are lots of energys from different sets, like Metal Energy, Darkness Energy etc. So my question is can you use any card called Metal Energy (or any other energy that has the same name and is from different sets) to use in official tournaments? Like could you use Neo Genesis Metal Energy but treat it as the R/S Metal Energy? Or do you have to use the R/S Metal Energy in order to use it in an official tournament.
