Pokemon Monotype Challenge

So previously, I made a topic about the Nuzlocke Challenge. This is a different challenge altogether, but can be just as difficult. The idea is that you play through one of the pokemon games, but only use one type of pokemon. For instance, I just completed a Psychic monotype run of Pokemon Emerald, with a team of: Gardevoir, Grumpig, Kadabra, Starmie, Solrock and Xatu. As you can see, they are all at least part Psychic. That is basically the only rule, all of your pokes have to be part of the same type. This means some types are impossible in certain games. So yeah, that's my challenge to you guys, can you complete a Monotype run? Post here with updates on them
