Sinistcha is the most physically defensive Ground-resistant Pokemon Ghost teams have access to, which is useful for dealing with Excadrill and Mega Swampert. It also pressures Grass-neutral Pokemon like Clodsire and Toxapex on Water and Ground teams with ease. Matcha Gotcha improves Sinistcha's longevity and lets it fish for burns against the aforementioned Pokemon neutral to Grass as well as common switch-ins like Celesteela and Alolan Muk. Substitute lets Sinistcha avoid status from Toxapex and gives it more turns to threaten a burn on would-be checks like Iron Hands and Mega Lopunny and chip down answers like Choice Specs Zapdos. Shadow Ball is usually preferred for its consistent damage output without relying on burns, but Hex lets Sinistcha further pressure opposing threats after they are burned. 96 Speed EVs let Sinistcha outspeed Adamant Azumarill, while the remaining EVs are poured into maximizing its bulk to weather Choice Band Excadrill, Ogerpon-W, and Mega Swampert better. Physical setup sweepers like Mimikyu and Ceruledge form a decent wallbreaking core with Sinistcha, dealing with special walls like Hisuian Goodra and Alolan Muk, while Sinistcha obliterates physical walls like Hippowdon and Great Tusk. Gholdengo loves Sinistcha's ability to remove Ground-types and in turn is able to wear down or remove Alolan Muk and Mantine, deal with prominent Knock Off users like Meowscarada if using a Z-Crystal, and take on Flying-types like Mega Aerodactyl and Articuno for it. Mega Sableye also absorbs Knock Off and can wear down opposing teams for Sinistcha with its ability to spread status and remove items.
