It's not a very strong attacker, but it's a very useful support Pokemon. It can heal teammates with Wish, and its Water Absorb ability helps it switch in on attacks. It can Baton Pass ridiculously huge Substitutes, too, thanks to its 130 base HP. Its special attack is still very high as well, on the same level as Jolteon (although that's about the only way it's on the same level as Jolteon
).
