This is the form Castform takes when hit by hail. In an experiment where it was placed in a freezer, it didn’t change to this form.

Castform Weakness

Castform's Normal typing leaves it vulnerable to Fighting. It shrugs off Ghost-type attacks completely. Only 1 weakness makes it relatively easy to build around defensively.

Ultra Sun & Ultra Moon Castform Best Moveset

One guaranteed turn is all Castform needs. Focus Sash buys it, max Sp. Atk and Speed EVs make it count, and Forecast adds something extra. The goal: deal early damage and deal damage with Weatherball. Fire coverage gives it play beyond just the lead turn.

Moves

Breadth over depth defines this movepool. Castform won't stack one type's damage ceiling, but coverage across 10 types means it always has an effective option. Last Resort and Double-Edge anchor the STAB core.
