What are your ultimate battle teams that you have created or would want to create if you had the time? No legendaries please.

I'm working on one right now, though I've placed some restrictions on myself:

1. Pick one pokemon from each generation
2. At least tree that are less commonly used (based on Smogon tiers)
3. I have to like their design

Here's my team:

Alakazam (Psychic)
Umbreon (Dark)
Flygon (Ground/Dragon)
Lucario (Fighting/Steel)
Volcarona (Bug/Fire)
Greninja (Water/Dark)
