I've explained most of the moves and stuff in the other answer so yeah. But there's a couple of things I should say:
It should be obvious but the physically defensive EV spreads are supposed to go with the specially defensive Amoonguss, and the specially defensive spreads for physically defensive Amoonguss. I might add a few more cores if I can find the time.
Psychic or Fire Blast over Psyshock due to the prevalence of physically defensive walls like Qwilfish.
Don't ask why I like the 252 / 196 / 60 EV spread so much, it's just because the numbers look cool :3 feel free to change it if you find something better but tell me as well :]
