This is my first team for battling, so please rate it.
I heard somewhere there is a rule that you can only use 1 item of each type, so yeah.

I also have many other pokemon, around 3/4 of the OU pokemon, so I can replace whichever you think needs replacing.

The Item Clause? Yeah, but not many trainers use the Item Clause anymore ~

I'd prefer Thunderpunch or Icepunch over Firepunch on Dusknoir.

Porygon-Z doesn't need Timid when it has Choice Scarf. Run Modest.

Everything else looks fine ~
