i'm not too much into this but there are a lot of cool users in the Wifi forum who will lend you free Pokemon if you're going to a VGC event. Otherwise you have to trade with other people for ones to practice with. Alternatively, you can also try practicing for VGC by downloading Pokemon Online and going to the SkarmBliss VGC server; they're good with VGC there, a lot more concentrated than smogon anyways. Also dw about hack checks, nobody creates illegal Pokemon here and gets away with it really lol
