Dual-type moves... ?

yes i would. i think it would make the games harder :P

No because the Dual-Type di chuyển was used bởi 2 Pokemon

I believe so. It would be interesting to see moves like that, especially if they made one for a legendary. I'd like to see an upcoming Legendary with a signature di chuyển that's dual-type. Like if it's Dragon-Psychic (that would be an interesting combo, I suppose), there could be a di chuyển like Divinistic Roar hoặc something (I just came up with a ngẫu nhiên name. It's the coolest I could come up with, deal with it).
