Castform's Normal typing gives it an immunity to Ghost. Only 1 weaknesses on top of that — it has plenty of safe switch-in opportunities. A competitive option since Gen 3. Needs some investment to avoid getting outsped.
Castform's stats barely vary. 0 sit in respectable range with no real gaps. It's a blank slate for EV investment. Worth 1 HP EV, medium-fast 1M XP curve to max.
This Pokémon can change its cells, taking different forms based on the temperature and humidity.
It has the ability to change its form into the sun, the rain, or a snow cloud, depending on the weather.
Castform Weakness
GoodCastform's Normal typing leaves it vulnerable to Fighting moves. It shrugs off Ghost-type attacks completely. Only 1 weakness makes it relatively easy to build around defensively.
No evolution chain to worry about here. Castform is a standalone Pokemon with no compatible partners for breeding through two egg groups. Eggs come out average hatch time.
How to Evolve
Breed Castform easily from the Indeterminate and Fairy egg groups. Pass egg moves like Amnesia, Clear Smog, Cosmic Power and 7 more to offspring.
Forecast isn't flashy, but it matters. Combined with Chopleberry for extra utility and HP-heavy investment EVs, Castform fills the defensive wall slot reliably. Bold nature finishes the spread.
