I'm gonna be quick with this one hopefully, as he's pretty self explanitory.
He can Use substitute, and get a decently beefy sub, He has Calm Mind to make him bulkier, and have higher Special Attack, which is a great thing to have.
He needs Hydro Pump to actually do something to most opponents, so we just have to ignore the lame accuracy, and Ice Beam is a high accuracy coverage move for Grass types, Flying types, and those annoying Dragons.
