Alright Preying Mantas, with Machop asleep, this is the perfect time to extend our lead.

Start by Imprisoning Sleep Talk if you can (if not, use Dream Eater), then use Dream Eater on your remaining actions if Machop is asleep, or if he wakes up, use Psychic on those actions.

If Machop wakes up, be ready to use Snatch on anything Snatchable (except for Rest), or Magic Coat on anything Magic Coat-able.

Edit: Dang, Preying Mantas can't learn Imprison...if my mistakes cause me to lose in the end, so be it.
