Keep in mind this is my 2nd post and I would like an opinion, I not a gengar user and thinking of using a strategy against my cousin. So please comment some suggestions of what I could replace, besides Destiny Bond and Shadow Ball, I am open to any other suggestion. keep in mind I am not a gengar user so I would like an opinion on my set.
Ability: Levitate (Shadow Tag as mega)
Nature: Timid (-Attack +Speed)
Destiny Bond: Low Health, use speed to take down your opponent with you.
Protect: Protects you when you Mega evolve in case your opponent switches out, if not you stay safe and think of a Pokemon you should switch in to.
Shadow Ball: STAB power and a chance of -sp. attack to your opponent, takes down Ghost and Psychic.
Sludge Bomb: STAB power with a chance of poison, also strong against Fairy and Psychic.
Please comment a few suggestions to Sludge Bomb and protect, maybe even ability.
