Eh, I wouldn't run Lanturn for bulky waters. Personally, I'd go for an offensive Celebi with Calm Mind, Leaf Storm, Recover, and Hidden Power Fire (maybe). That way you OHKO Swampert, have a good killer for Suicune, and you don't die to Earthquake. With Lanturn's 67 base speed, everyone is gonna have a field day outspending it and Earthquaking it.
