So what the hell is going on with dual typed attacks? We got pic related, but as far as I know we never got any confirmation on how exactly this move works, and if there are others like it. I've heard rumors about a new move called light ray which supposedly does grass/electric damage, and that oblivion wing deals dark/flying damage, but if any of that is true you'd think we'd have proof by now.

I also saw a ton of people on smogon talking about electric terrain and misty terrain, which are supposedly new weather conditions, but again, no proof.
