I think sash should be the first slash, you are gonna hard time getting anything off without it. Sheer Force isn't worth it just for Rock Slide so just move it it oo.
I'm gonna qc this like its a skeleton, but the comments need a lot of work. First of all they need a lot more fleshing out, right now they are too brief. Secondly make sure the Pokemon you make references too are actually relevant parts of the meta. Thunderbolt Gardevoir for instance is not. That said, 1/2.
