Creating a team. 1/6 done. in need of suggestions

They could change your Scizor's nature to Hasty, Naive, or Jolly.
So you might want to trie it a few times

Berries don't change the nature. The only way to get a new nature is to capture another Pokemon or breed the Pokemon.

Here is the Baton Passing Umbreon you want Naos:

Umbreon @ Leftovers
Synchronize / Bold Nature
EVs: 252 HP / 252 DEF / 6 Sp. DEF
- Mean Look
- Wish
- Baton Pass
- Toxic

I am currently working on an Umbreon myself. Would be perfect if it could learn Reflect!
Currently sticking to this:

Umbreon @ Leftovers / Flame Orb (to make use of Synchronize)
Ability: Synchronize
Bold Nature
- Mean Look
- Baton Pass
- Wish
- Toxic / Yawn

Hope it helps.
EDIT: The guy above beat me :(

Baton Pass
Assurance/Pusuit/Iron Tail/Confuse Ray
Confuse Ray/Mean Look
