Ash's Best Possible Team

What would Ash's best possible team be for the Sinnoh League or the Elite Four?

I think it would be this:

Pikachu
Charizard
Sceptile or Bulbasaur
Squirtle
Snorlax
Swellow or Staraptor or Glalie


several of Ash's pokemon are very good, but I don't think they are good enough compared to these guys. For example: Torterra, Infernape, Buizel, Muk, Kingler, etc

it might change, but from the top of my head, this would be a good group
