Is Gastly Good in FireRed & LeafGreen Playthrough?

Ground attacks pass right through. AbilityLevitate makes Gastly immune to Ground, which is new for the remake. Ghost/Poison with Ground immunity removes one of the two weaknesses. Gengar at trade evolution is the target. Levitate makes the entire line safer than it was in the originals.

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. 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.
