I have DDA so no requests, since i could not fullfill single requests without forgeting someone, but I'll bring a full box of each these mons from 3ds:
Shiny Jirachi
Shiny Necrozma(i'm not sure if it can be traded tho)
Shiny Zekrom
Shiny Reshiram
Shiny Kyurem
Zeraora
Marshadow

Do you suggest any other species for a give away? (no Meltan or Melmetan sorry, nor Gen8 exclusives)
