Base Stats

Castform has a perfectly flat 70 in every stat for a 420 BST — balanced but unremarkable everywhere. There is no investment-free way to make it hit hard or wall reliably; its value comes entirely from the Forecast typing flip and a sturdy enough base to throw out one good Weather Ball per turn.

Type Matchups

Abilities

• Forecast — Castform's only ability and its entire identity. In harsh sunlight it becomes Fire-type, in rain it becomes Water-type, and in hail it becomes Ice-type (reverting to Normal in clear weather). This changes both its STAB and its defensive matchups on the fly, so its weaknesses depend on the weather currently in play.

Best Moveset

Weather-flex special attacker

• Weather Ball — the core move: it becomes a 100-power Fire, Water or Ice move matching the weather, and gets STAB because Forecast has already changed Castform's type to match. Effectively a free chameleon nuke.
• Hurricane / Thunder — coverage that becomes perfectly accurate under rain.
• Ice Beam or Fire Blast — reliable backup coverage independent of weather.
• Protect — keeps Castform alive while the weather it needs is set.

For support builds it also has Tailwind, Icy Wind, Thunder Wave, Defog and Cosmic Power, plus Scald, Energy Ball, Shadow Ball and Tera Blast.

Suggested SP Spread

With the Champions SP system (66 points, max 32 per stat), Castform's even spread means you choose its direction entirely through SP: pump Special Attack and Speed with a matching Stat Alignment for a Weather Ball attacker, or HP and Special Defense for a support build. Test the numbers in the team builder.

Competitive Role in Regulation M-A

Castform is a weather-team flex pick rather than a meta staple. On a sun or rain core its Forecast typing means Weather Ball is always same-type and always 100 power, and it can flip its defensive profile to resist the moves the weather encourages. The catch is its flat 70-across stats: it never hits especially hard or takes hits especially well, so it is outclassed as a raw attacker and survives mostly on the type changes. Treat it as a low-investment weather utility and Tailwind/coverage body that demands the right weather to function, not a standalone win condition.

Evolution Line

Castform does not evolve and does not Mega Evolve. Its only transformations are the temporary Forecast weather forms (Sunny, Rainy and Snowy) triggered by active weather.
