leftovers isn't shitty against HO, it's just that it generally comes down to a speed tie. you can still bluff a scarf on lefties ditto if it comes in after a death, meaning they might not attempt the tie, but he can't bluff a scarf the rest of the time, what with Stealth Rock and all. is leftovers really necessary on stall-destroying Ditto, considering most stall mons have recovery?
