For that shiny Banette of yours, I can offer 2 of the following shinies: Aromatisse, Pangoro, Machamp, Swanna, Quagsire, Panpour, Gulpin, Vanillite, Larvesta, Sigilyph, Archen, Scrafty, Whiscash, or Corsola. I wouldn't be willing to trade 2 different Gen VI shinies for it, but you can have any combo of 2 shinies from that list other than what I just said. XD
