Gengar has a wide selection of attacks in Pokmon GO, but there is one moveset that stands as its best compared to other combinations. The final evolution from the original set of Ghost-type Pokmon, this Gen-1 head of the Ghastly family is still a fan-favorite for good reason. With a high attack and a selection of resistances, the broad-grinning purple ghoul can be a great member of your team in the right circumstances.
