Hi, i have a shiny Lapras, lv 1, perfect ivs exept attack, modest nature, egg moves: dragon dance, dragon pulse, ancient power and freeze-dry.
I also have a shiny Blaziken, lv 51, perfect ivs except sp. attack, adament nature, egg move: baton pass.
I'd definitely be interested in that blaziken.

Yes, so long as you're North America. The code is region-locked.
