You're not gonna like it, but gimmick support is all Lop's got left.
Base 105 speed is usable but not great. Thunderwave, Charm, Fake Tears, Attract and Magic Coat are all at least moderately useful.
Fake Out, and Circle Throw for utility.
Healing Wish after a Thunderwave might be all you can get off though given low bulk.
Scarf Switcheroo still works.
Klutz Switcheroo is situationally useful.
The rabbit is not good. That said I'm gonna try King's Rock Triple Axel. Once I find someone willing to tutor it that is because fuck Gamefreak for charging for this baby's first dating sim for Kubfu.
