Castform Best Moveset

AbilityForecast changes form and type based on weather: Fire in sun, Water in rain, Ice in hail. 70 across every stat gives the moveset balanced mediocrity. The type-shifting is unique but no form has stats that threaten. Functional gimmick without the power to matter.

Gen IV — Diamond, Pearl & PlatinumC

Weather support was stronger in Gen IV (Diamond & Pearl), but 70 offenses behind any weather STAB wasn't threatening. The gimmick was the design, not a competitive strategy.

Gen V — Black & White / B2W2E

Permanent weather from abilities in Gen V (Black & White) should have helped. Every dedicated weather abuser had better stats. Castform was the jack of all weather, master of none.

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.

Castform Guide

  • Watch for Machamp (Fighting) when using Castform. They all hit it super-effectively with STAB. Only 1 weakness means fewer dedicated counters to worry about.

  • It depends on your team. Castform at 420 BST isn't a powerhouse, but the Normal coverage might be exactly what you're missing.

  • Castform has a 420 base stat total and ranks as C-Tier: a situational pick that fills a niche. It works best as a balanced.

  • Forecast changes Castform's type and form to match the weather. That's the one you want on Castform. It's the only ability Castform has.

  • Castform fills the balanced role. It's a special attacker with base 70 Sp. Atk. Base 70 Speed is workable. Faster than some, slower than many. And it's enough bulk to take a hit or two.

Game Availability

Castform first appeared in Ruby & Sapphire and has been available in 13 games across 8 generations. Obtainable through wild encounters in most titles where it appears.
