I thought id try to get a shiny ponyta the other day using the masuda method in pokemon white (which gives me a 1/1366 chance of getting a shiny per egg), so far ive got 700 NORMAL COLOURED Ponyta's and no shiny

, still trying but has anyone else had any experience in shiny hunting? ive had a few before but this is the first time using this method and im wondering if anyone has any tips?
