Magikarp is listed as a Water type in the current Pokémon Champions format, with usage data pulled from competitive teams, tournament results and Showdown-ready pastes tracked by MetaVGC. This page brings together its most common moveset, nature, ability, item, teammates and type weaknesses so you can judge where Magikarp fits in a VGC team.
The most common build highlights Rattled, Assault Vest and Hardy 0/252/180/0/76/0. Its frequent moves include Flail, Splash, and Tackle. Treat those choices as a data-backed starting point: they show what players are bringing, while EV spreads, Tera Type and the final move slot should still respond to your expected matchups.
Defensively, Magikarp has important weaknesses to electric 2x, grass 2x. That matters during teambuilding because a strong composition needs ways to cover those attacks without giving up offensive pressure. Partners such as empty, Espathra, Slaking, and Tornadus appear often because they can add positioning, type coverage, speed control or safer switches into common checks.
