Ghost and Dark attacks are super effective against Ghost type pokemon.
You get a Pokemon that's effective against Phychic or Flying. Personally, I wouldn't defeat Lugia...
Defeat Giovanni In The Sliph Co. And It Is Gonna Be Unlocked.
ghost types, dark types, bug types, i think that's it tell me if im wrong
Psychic, and if you're talking about the gym leader from Hearthome City that uses Ghost Pokemon, then no.
Ghost-type Pokemon are strong against Psychic-types. This is because Ghost-type moves are super effective against Psychic types, giving them an advantage in battles. Additionally, Dark-type Pokemon are also strong against Psychic-types.
any pokemon can beat a psychic pokemon if used well enough in battle, but the types of moves that are super effective against psychic types are bug dark ghost in generation 1 (red, blue, yellow) bug type moves were the ones super effective against psychics, while ghost type moves do not effect psychic types at all.
Water type are good against fire and ground and rock type . Ice are good against grass and water and phychic. Hope this helps! :)
mostly phychic types like Abra
Fire and phychic work best for me :)
The elite fours Pokemon are all lvl 50ish so have a good team at about lvl55+ and you should be okay I recommend taking a dark Pokemon because it will be super effective against two of them the elite four are types are, ghost phychic dark and fighting you can fight them in any order you want
I'd think that if Luxray can learn dark moves, and Alakazam is phychic, and dark is super effective to phychic, i'd think that Luxray is stronger.
