yall just thought of monotype challenges? i beat the first generation of pokemon games with a new file for each type. the easiest one to do it with is psychic. get an abra and train the hell out of it. in Fr/Lg train it from where you catch it, defeat misty, defeat Lt. Surge, teach the shockwave TM you get from him to your kadabra, then, you are unstoppable. defeat every trainer in the game using only the kadabra. he will be above level 90 by time you beat the elite four the second time. guarunteed. let me know how this works for you.
