Looking for items:
Leftovers
Pokémon X exclusive mega stones (tyranitite, manectite, charizardite x, mewtwonite x, pinsirite)
Assault vest
Choice Scarf
The latter two aren't priority, but they would save me some time in the Battle Maison. The leftovers is the one I really need.
I can offer some hidden ability pokes (including the following: Ponyta, Pyroar, Fletchinder, Mankey, Throh, Riolu, Spearow, Woobat, Rufflet, Electrode, Helioptile, Galvantula, Sandshrew, Wooper, Nincada, Camerupt, Diggersby, Abra, Sigilyph, Heracross, Ledyba, Volbeat, Beautifly, Vivillon, Gabite, Dragonair, Druddigon). There could be more, those are the ones I remember.
Could also offer breeding spitbacks for the following pokémon - Mawile, Rotom, Riolu, Kecleon, Pachirisu or Taillow.
Thanks!
