Bug types and dark types and ghost types are super effective.
Fantina's weaknesses are only dark types. Normal and fighting won't effect her, she will KO psychic types, and any other types are just normally effective. (Try teaching your Pokemon moves like Crunch or Faint Attack, Shadow Ball is actually ghost type)
grass types are
Poison and Steel types are super effective against Fairy types.
Basically the only weakness is water, other types are normally effective or not effective on fire at all.
there are your shadow and other's shadow!! lol!!
no except UV lights as they do not portray any shadow
use a grass type like roserade because it is super effective against ground types and can help you beat lucian's psychic types as roserade can learn shadow ball too :)
no some types of glass can have no shadow
Poison and Steel types are super effective against Fairy types.
Sadly, normal is not super effective against any type. Beware, though. Fighting types are super effective against Normal!. Do not use Normal types against Ghost, or Ghost types against Normal, because they don't effect on each other!. (Example) Go Gengar! Go Snorlax! Gengar use Shadow Claw! It had no effect! Snorlax use Body Slam! It had no effect!
it is super effective against normal types, ice types, rock types and dark types

Weakness as in types? Like psychic moves aren't effective on a certain type? Well, psychic has no effect on dark-types, not very effective on psychic-types (DUR), and not very effective on steel-types. Although, if you were wondering what psychic will LOSE against, (as in super effective types that damage psychics greatly), the the types would be dark-types, bug-types, and ghost-types. Hope I helped! :)
