i dont think they work...
cause like.. wehn i use my dark.. then it says
wait wait.. is dusclops a dark or ghost pokemon???
I'm not entirely sure about Dusclops, I think its ghost/rock, because its weak to water.
dusclops is a ghost type.
sorry "potato_chips" but ghosts arent weak against psychic, they're weak against ghost and dark type.
and normal types are the only ones that arent effected by ghost type attacks...
