Gyarados beats Marowak, Heracross, Machamp, Blissey, and Entei, as well as Exeggutor and other Leech Seed users. Toxic is used with Substitute to win the Exeggutor matchup and force opposing Rests.
Marowak destroys the Electric types that Gyarados is weak to, beating Raikou, Zapdos, and Jolteon as well as Blissey, Gengar, Tyranitar, and Dragonite + Jumpluff with Ice Beam.
Raikou beats Skarmory, Encore Alakazam, 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.
