Lets say that someone else wants to trade me his Tornadus in his Therian Forme even though I already have one in my pc. Can I have as many as I want in my pc? i wonder this because in the Pokemon dream radar game, you only are allow to catch it once. So this means that you are not allow to have more than one landorus, tornadus, or thundurus in their therian forme in your pc? Please clarify my doubt.
