This is just you're average, every day Special Attacking Skymin... but with one big twist: Healing Wish. I know this is given a short mention in other options onsite, and it can be a bit situational... but oooh boy, when you find the situation to use it, it can be a total shocker that can win you the match! The idea here is that you use Skymin on a very offensive sort of team, since not only does Skymin have plenty of its own fire power, it also doesn't really last too long on these type of teams, and that speed makes it one of the best Healing Wish users out there! When Skymin is gonna die from SR or you just think it isn't going to be useful anymore, you use Healing Wish on scary sweepers like Mewtwo, Rayquaza, or Arceus. While they will still take hazards damage, Healing Wish doesn't actually switch your target in until the end of the turn, which means these dangerous Pokemon ALSO get a free switch-in! While it's more situational than say... HP Ice / Fire or Growth, I found that the pay off was usually FAR bigger than any of LO Skymin's other moves, and lets face it, without spin support, its not like LO Skymin usually lasts long anyways lol.
