Yamask is a Ghost-type Pokemon from Unova. It is known for carrying a mask and for evolving into Cofagrigus, while its Galarian form follows a separate evolution path into Runerigus.
Competitive Overview
Yamask is usually more important as an evolution-stage Pokemon than as a major standalone competitive threat. Its defensive typing, status moves and access to Eviolite can give it niche value in lower-power formats.
Yamask often relies on moves such as Will-O-Wisp, Hex and Pain Split to disrupt opponents. Its main drawbacks are low Speed and limited offensive pressure before it evolves.
