Nothing to choose from here. However, we don't want to use Castform as a physical sweeper.....
Notable Special Movepool:
Weather Ball **
Water Pulse
Ice Beam / Blizzard*
Solarbeam
Thunderbolt / Thunder
Shadow Ball
Flamethrower / Fire Blast *
Energy Ball
Ominous Wind
This movepool allows him to take adavantage of his trait, Forecast. * Denotes that with the respective weather, it gets STAB. ** denotes that it always get STAB unless in Sandstorm
Utility:
Substitute
Amnesia
Psych Up
Sleep Talk
Thunder Wave
Endure
Rain Dance
Hail
Sunny Day
Toxic
Some really excellent options to pick from here
Possible Movesets:
Castform @Life Orb / Damp Rock / Heat Rock / Icy Rock
Trait: Forecast
Nature: Modest
EVs: 104 HP / 252 SAtk / 148 Spd
~Hail / Sunny Day / Rain Dance
~Weather Ball
~Solarbeam / Thunder / Flamethrower
~Thunder Wave / Ice Beam
Typical moveset. With Hail, you run STAB Weather Ball with Flamethrower to cover most things except Water types. Sunny Day runs Solarbeam, but gets walled by dragons, so consider Ice Beam on the last slot. Rain Dance runs Thunder and is only walled by Quagsire. Thunder Wave is used to mediate faster stuff
So discuss the cloud. Will he see use in UU? With Para support, could he pass up to BL? It's hard to tell. One thing, it's extremely versatile and unpredictable, so that's a plus. However, bad stats ruin it's reliability.
