Nothing fancy in Gastly's spread. It leans special with Sp. Atk out front. And you'll get 1 Sp. Atk EV per KO for it. Follows a 1.06M XP medium-slow curve.
It wraps its opponent in its gas-like body, slowly weakening its prey by poisoning it through the skin.
Its body is made of gas. Despite lacking substance, it can envelop an opponent of any size and cause suffocation.
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.

Moves
Most of Gastly's flexibility comes from TMs. Same-type output runs through Gunk Shot and Poltergeist, but Dark and Psychic and the rest of the TM pool push it from predictable to genuinely threatening.
Level-Up Moves
TM Moves
Egg Moves
Tutor Moves
Most of Gastly's flexibility comes from TMs. Same-type output runs through Gunk Shot and Sludge Bomb, but Psychic and Ice and the rest of the TM pool push it from predictable to genuinely threatening.
The offense anchors on Sludge Bomb and Shadow Ball, with coverage across 7 types adding reach. It's a workable movepool for Gastly that handles most situations. Energy Ball and Psychic give it enough punch where it matters.
Egg moves make a real difference. Gastly gets Astonish and Clear Smog exclusively through breeding, filling gaps that TMs and level-up can't touch. Coverage across 8 types rounds out the picture alongside Sludge Bomb and Shadow Ball.
