well its a normal move so technically no
It lowers evasiveness and lets normal attacks work on ghost pokemon ^_^
Ghost pokemon are good against psychc and ghost.
It is a Ghost/Dragon pokemon.
Ghost or dark pokemon
Because Ghost Pokemon can't see in the dark.
Ghost-type Pokemon are weak against Ghost and Dark types.
Ghost type Pokemon are immune to normal types moves,but anything else can hit them.their weakness is a psychic type move... So the answer is psychic type Pokemon or any Pokemon that knows psychic moves (interesting how a dude in the anime says ghosts can beat psychics,but its the other way around in the game..)
Gengar is the fastest Ghost type pokemon.
Since mismagius is a ghost type Pokemon counter with a dark type Pokemon like honchkrow.
You can beat a ghost type with another ghost type (Like Haunter)
Currently, the only Pokemon that is a Ghost/Electric-type is Rotom.
Either you'd have to wait for it to use Struggle, or use a pokemon that knows a move that would poison the Shedinja. Shedinjas can still be poisoned. Chances are one of your pokemon would know a flying, rock, ghost, or fire type move.
