Changes in bold.

I'm surprised you got 3rd place with a team as shitty as this.

Edit: I forgot to put, go with Pressure on Aero.

No, I had a different team. It was with Ghost, Dark, and Poison types.

If you can post the select normal types that are allowed, it would help.

Also, the changes Nellie made look good, there isn't much else to expand on after that.

It's up now!

I'm assuming this is an in-game team then? If so, how dedicated are you to breed for natures and re-level some pokemon.

I don't really understand natures so much....

Some natures like docile are neutral, so theres not much to worry about, Of course a beneficial nature would be better.
The changes nellie did are very useful, so try to get them as that.
BTW nature breeding is not working for me for some reason x_
