Alright, after a couple of tries, I've realised that Clefable is a major pain -_- I tried to set up Quiver Dances, but I didn't do enough damage to even wittle his HP after both the healing from the grass and Ingrain. I also don't have that many steel types besides a Mawile in my box, and I'm not sure if any of the move tutors have steel moves to teach.
