I just finished my first pokemon.
It's a 5 max iv, 252 atk, 252 spd, scrappy adamant Khan.

I'm wondering what I should make next. That would compliment a Khan. I absolutely love..

Charizard
Blissey
Heracross
Scizor
Wobbuffet
Skarmory
Dragonite
Crogunk

Which of these should I ev/iv train/breed?
Also, I've asked this a few times but which of these shinies should I MM? I just can't make a decision about anything.
