Yes, the HGSS design I think fits her character better as a psychic, it looks a little more artsy and free-spirited. The first design is harsher where her clothes look more like a uniform and she carries a whip, I think a design like that does fit the anime and manga Sabrina well who is introduced as much more sinister character, but that's not really her personality in the games. So yes, I think the HGSS design is more appropriate than some of the earlier designs. My favorite Sabrina though is actually the gen 5 Sprite at Pokestar studios with the whole gothic, Edwardian thing going on.
The person below me knows what happens when a flying type or levitating pokemon uses dig, and it's opponent uses earthquake. Are you still invulnerable or not?
