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.
It alters its form depending on the weather. Changes in the climate such as the temperature and humidity appear to affect its cellular structure.
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.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
No evolution chain to worry about here. Castform is a standalone Pokemon with a decent partner pool for breeding through two egg groups. Eggs come out average hatch time.
How to Evolve
Breed Castform easily with 22 breeding partners from the Indeterminate and Fairy egg groups. Pass egg moves like Future Sight, Psych Up to offspring.
This build takes hits and hits back. Leftovers provides passive recovery each turn, Forecast supports the gameplan, and max Sp. Atk and Speed EVs mean Castform doesn't crumble to chip damage. Plus Electric coverage backing it up.
