>>41583468Diantha is in a tough place because there's not a lot of Gen 6 Pokemon to work with.
Gardevoir is her ace and represents ORAS and Mega Evolution, so it's good. G.oodra and Aurorus both fit her elegant theme, and Gourgeist is also feminine. But the problem is that there aren't a lot more elegant Pokemon in Gen 6 that fit that don't overlap her other types.
Florges seems like the best fit but it's both Grass and Fairy. Aegislash would be a better fit than Hawlucha since it fits a "regal" theme. Hawlucha should never have been considered at all. Espurr could also be a good choice (but its Psychic typing overlaps)
