It's not an opinion when it's plainly wrong. I agree with the rotom ones, and I think bite should be switched back to normal type. There isn't anything dark about it except for harming something, which is what all moves do.
I'd have to say Alakazam. If you can trade it over from Emerald, it can have Psychic and the three elemental punches. When combined with it's massive special attack stat, it can take down many things in its way.
