Yanmega works well as a starter, due to its ability to scout out attacks and force other common starters to switch or die, not to mention the fact that Stealth Rock isn't in play on turn 1. Hippowdon, Swampert and Bronzong are all common leads who carry Stealth Rock, so you can send them to sleep with Hypnosis, preventing them setting up the entry hazard that plagues Yanmega. If you are not facing a slow, defensive enemy, Protect first turn, as it gives Yanmega a free Speed Boost. It also allows you to scout a Choice item user's attack and switch to the appropriate counter if necessary. Be careful, though
