you missunderstood me.....i mean a pokemon that realy under any circumstances will not be obtainable in B/W can not be RNG´d because it does not exist....
@kaZowar: please no long discusion if RNG is legit or not.....as both methods are in a grey area....exept the AR is more handsome for bad people that create "Super-Power-Pokemons" with modifying IV/EV values, Init., Def.,Attk., Speed and so on.....so that they have at least an Imba Poke that might work on some online/wifi or IR matches.....but destroys the whole fun.....i for myself see no sense in these codes.....as if you realy are a Poke-Freak you´ll allways try to get the "perfect" Poke on natural and more legit ways....
