Castform

Castform holds a 0% usage rate in singles and is practically absent from the ladder. As a Normal-type with 70 across every stat, nothing stands out. Forecast relies entirely on weather support, and a Fighting weakness compounds the issue. It lacks the damage output or utility to carve out a role in 6v6 singles.

At 0.02% doubles usage and rank 241, Castform sits on the fringe. Forecast lets it shift typing and gain a STAB multiplier under any of the four weather conditions, and Weather Ball becomes a 100 base power STAB hit in the right weather. Its 70 base speed and offenses cap the ceiling, and it requires dedicated weather support. Choice Scarf builds try to give it a niche as a fast utility attacker, but it remains a marginal pick.

Playstyle：Doubles builds center on Weather Ball coverage, with Life Orb at 73.8% for raw power and Focus Sash at 22.9% for survival. The top moves split nearly evenly across Thunder, Blizzard, Hydro Pump, and Fire Blast at 17%–20% each, giving broad coverage. Icy Wind at 8.1% and Thunder Wave at 5.4% add speed control, while Choice Scarf at 19% shows some teams lean on outspeeding key threats.
