While Healing Wish looks good on paper, I haven't found it all useful, but perhaps that's just because I haven't built a team with a Healing Wish Lopunny in mind (mine really benefits on the coverage Ice Punch gives a lot). Even still, though, on a solid HO, I'd say that's worth the slash - but what is Toxic doing? I'd think even PuP would be a better slash than that (because that allows you to break so much more stuff). On paper, you can lure Clefables and Quags and Slowbro or whatever it is you'd like, but Lopunny is a Pokemon that fits on HO more, and Toxic on HO, a playstyle with such few turns, doesn't seem too idealistic to me. That said, I haven't tested Toxic or Healing Wish, so I don't speak from experience (but I do speak as a Lopunny-user experience in general).
The SubPass looks really sketchy. Opinions from others who have used that set, please? (On the other hand, SubPuP looks amazing, or even SubEncore.) (Also, if you don't use Shiny Lopunny, she'll miss every HJK.)
