Hmm... I'll see about that code then... thanks for linking me to that Landorus :)
Also, you're totally right about this whole deal being BS. I'm actually fine that they put in Palkia, Dialga, Giratina, Ho-oh, and Lugia in the game... because we can trade with someone who did purchase the game.
However, in its current form, there is absolutely no legal way of obtaining ANY Therian Forme Genie without owning a copy of Pokemon Dream Radar (A 3DS game I might add, for a DS Pokemon game). Locking certain Pokemon out completely (as you said, they are very good in VGC, etc.) is a huge pain and a jab in the face to us. It's OK to give pokemon like Dialga which can be traded, etc. but this was just a bunch of loops GF wanted us to jump through.
