So, to get this rock, I need to land 2-3 super effective hits per enemy, and then get lucky?

I need exceedingly weak pokemon to be able to land 2-3 hits, but I need exceedingly strong pokemon to tank the damage he's gonna pump out.
So, Avalugg is a given. Who else has terrible resistance and a good coverage move set?
