Wailmer is technically a pre-evolution of Wailord, but it holds its own in formats where Eviolite is allowed. Only weak to Electric and Grass. Flexible enough to run physical or special sets. Part of the Gen 3 roster.
The stat line revolves around HP. Percentage recovery gets extra mileage here. Attack backs it up, though Defense doesn't pull its weight. Worth 1 HP EV on a standard growth curve to max out.
