Spotlighted Mega is Mega Medicham, a.k.a. the nastiest breaker from Gen 7 OU, a.k.a Mega Catch these flouting hands, a.k.a a.k.a.. Built around a decent semi-balanced offense team and a scarf Nature power heatran to smack Ash Greninja, Tapu Fini, Slowbro, and Toxapex with a Nature Power Thunderbolt as they're one of the rare few switch-ins to Eruption. The idea of the team is to eliminate Garchomp's main answers (Slowbro and Corviknight) with Electric Spam so that in late game scenerios it can SD up and go for game. (super optional to chance Garchomp into Z-Rock w/ stealth rocks over scald shot). Rock Slide on AV Tang as Zard Y and Volc are problems for this team.
