Furthermore, these two games have the explosive level curve so it can easily level up if you fight higher-leveled Pokemon. There are also good methods to increase your EXP in both games:
- BW: Lucky Egg + Audino + Exp. Powers
- BW2: Lucky Egg + Breeders in White Treehollow or Audino + Exp. Powers
- SM: Lucky Egg + High-leveled trainers
- USUM: Lucky Egg + Rotom Exp. Power + Wild Chansey/Blissey
And ORAS has the Blissey bases for the wild Rufflet in Mirage Islands.
