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.
Its appearance changes with the weather. Recently, its molecules were found to be just like water.
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.
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)
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 31 breeding partners from the Indeterminate and Fairy egg groups. Pass egg moves like Amnesia, Disable, Future Sight and 3 more to offspring.
Forecast isn't flashy, but it matters. Combined with Life Orb for extra damage on every hit for a health trade and max HP and Sp. Atk EVs, Castform fills the special attacker slot reliably. Quiet nature finishes the spread.

The natural movepool does the job, but Amnesia and Disable from the egg pool give Castform something extra. Pair those with Last Resort and Double-Edge for STAB and coverage across 8 types for reach, and the kit fills out nicely.
