The idea here should be fairly obvious; boost and try to sweep. Yes, it's slow, but its only weakness is Grass and it's not susceptible to a Thunderbolt crit from Jolteon like Tobybro. It also has access to Recover, allowing it to boost without Resting. The slightly higher special and HP are pretty much negated by Slowbro's higher defense. It certainly doesn't outclass Slowbro, but it does have its advantages as outlined above.
