 ## Thanks
 
 We would like to thank the [Smogon community](https://www.smogon.com/) for allowing us to use and serve their custom B&W-style sprites for the Pokemon with IDs greater than 650. Check out their free and open-source Pokemon Battle Simulator at [Pokémon Showdown](https://github.com/smogon/pokemon-showdown)
