Gastly Weakness
Gastly is weak to Ground, Psychic, Ghost, and Dark. On the flip side, it's immune to Normal and Fighting-type moves entirely. The Ghost/Poison typing picks up 4 resistances to work with. Levitate grants an additional Ground immunity, reshaping the matchup chart. Gastly leans toward special offense (base 100 Sp.Atk) instead of trying to wall anything.
