Have you ever done a monotype run in a Pokémon game before? If so, what game and what type? What did your team look like?

Currently doing a Grass-monotype run of Soul Silver and it's been pretty tough. I'm at Morty and my team is Bayleef, Weepinbell, Skipbloom, Parasect and Exeggute. The game seems to have been made to hate Grass-types, so it's been fun trying to find ways around Pokémon that destroy my team.
