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.

| 2x (Weak) | Ground, Psychic, Ghost, Dark |

| 0.25x (Resist) | Poison, Bug |
| 0x (Immune) | Normal, Fighting |

Moves List
Egg moves make a real difference. Gastly gets Astonish and Explosion exclusively through breeding, filling gaps that TMs and level-up can't touch. Psychic and Normal coverage and more rounds out the picture alongside Sludge Bomb and Shadow Ball.
