Robin's speciality would be Psychic types, but she'd also have some flower themed Pokémon. I'd see her use Pokémon relating to history, like Claydol, Bronzong or Sigilyph, as well as Grass types like Roserade or Lilligant. Out of the ones seen in the pic, the best fit is Natu/Xatu. If she'd have a varied team of different types, then I'd say something like Claydol, Roserade, Milotic, Florges, Mawile and Togekiss.
