Castform does not transform with the Mystic Water. Castform's forms are entirely based on the weather effect currently active in battle.
You cannot obtain Castform in-game. However, you can obtain one Through pokewalker on the course Treehouse but I can't go into detail as I don't understand it that much.
It doesn't, Castform doesn't evolve into anything. Actually it sort of evolves. It changes it's from to sunny castform..when it's sunny. Rain castform...when it's raining. Snow-cloud castform...when it's snowing. But it only changes when those affects are used on the battle-field
Castform is #351 in the national pokedex, and it is a Normal type Pokemon.
No, I do not believe Castform is a legendary. I think he was made by Humans in order to control the weather.
Castform learns the move Weatherball, at level 30. This is the last move it can learn.
Castform can be found in the Trophy Garden in Pokémon Diamond.
