My mentor said to try out the Battle Factory. Well it was going to be my 3rd streak (I already got the silver symbol so I didn't see Noland), but it was... easy! The thing that made it easy was that the guy always said the trainer was using a certain type (until the 5th match). Also, the AI seemed kinda stupid... instead of finishing my Gardevoir off, the pokemon I was facing (forgot what it was) let me recover to full health with leftovers, all the way from the red zone.
