Gyarados beats Marowak, Heracross, Machamp, Blissey, Moltres, and Houndoom, as well as Exeggutor and other Leech Seed users. Substitute lets Gyarados avoid status and some low accuracy moves, Mystic Water boosted Hydro Pump 2HKOs Tyranitar.
Marowak destroys the Electric types that Gyarados is weak to, beating Raikou and Jolteon as well as Blissey, Gengar, Tyranitar, and Jumpluff with Icy Wind.
Raikou beats Skarmory and Water types like Vaporeon and Suicune for the team. It does very well in Electric mirror matches with Crunch and Rest. Reflect helps vs Ursaring and other physical attackers.
