My best advice is to start out with pokemon showdown as you can build teams with any pokemon you mentioned and aren't limited to your own cartridge game. Honestly having walls like Chansey and Weezing aren't worth running in a VGC team. The other pokemon you'd mention are instesting options but I really don't know what mega charizards cusually run in VGC (preferably a bulky investment).
