Well, I have had a friend hack me one for use in the Battle Subway, and the results are questionable. Granted, this was before BW2, so its moveset is Giga Drain, HP Rock, Glare, and Leaf Storm.
I personally cannot wait to aquire a legit one. In other news though, I have aquired legit DW Politoed, Ninetales, Blaziken, and Venasaur ^_^
