Atlas, not to be insulting or anything but that's the kind of reasoning I would expect from a ten year old fanboy from Serebii. The only thing even remotely competitive from your post is that you would like Psychic to make things like Trick Room etc. make sense flavor wise.
EDIT: Sorry if I'm mini modding Sunday I just get mad when I lose a poll to posts like this.
1. Electric because Thunder Wave and the screens are good support moves. We could easily fit Gravity and Trick Room on flavor wise so that's not an issue. Flying is a great type to be resistant to in our CAP server, and resisting one half of Boltbeam (and the half that usually has more BP as most electrics use HP Ice) is good too. Sure it has a 4x EQ weak but that could help balance it. Many good Pokemon have 4x weaks, and this isn't really a wall, it's a utility. Remember, Deoxys-S can be played as utility, and it doesn't have the best defenses/typing either. Electric/Poison would let this Pokemon have useful resists without a terrible STAB. If it wanted to stop a Gyarados sweep, or scare Skarmory away, it could.
I'll decide my secondary later.
