Spread notes:
Tyranitar outspeeds Tornadus at +1 - the bulk was more important to us than the ability to outspeed Koko. Takes 4 Seismic Tosses, hits an Atk jump point, SpD dump
Kart takes Mega Metagross Hammer Arm or LO Koko Tbolt, max Speed for opposing Kart since the team's only real check was Volcarona and it can't redirect
Tapu Fini outspeeds Pheromosa in TW, takes <50% from Mega Metagross Iron Head, dump in SpD since we didn't need the SpA as much with only one attack + NM
Kyurem-B takes our own Kart spread's All-out Pummeling and outspeeds -1 Zard Y; going for the Fusion Bolt OHKO on Zard Y meant Brave was most efficient, SpA dump
Landorus-T outspeeds Modest Heatran, which was actually kind of a threat since Fini didn't have a Water move, standard otherwise
Volcarona takes Terrain-boosted Mega Metagross ZHB, outspeeds scarf Gene/Tini, dump in SpA
