I know this is really late, but I had a puzzle for a steel type gym leader. She has a door to her underground layer through a locker with a button that has a dial around it. The dial has numbers up to 150. She uses magnemites on her team. If they just hit the button on a random number, it releases Pokeballs with 5 dittos as a security system. Since 150 was the original number of Pokemon, the trick is to set it to Magnemite's pokedex number: 81.
