In the Masuda Method, eggs are collected from both the mother and the father Pokémon and are then put in the same daycare. This gives the eggs a 1 in 4 chance of being shiny, as opposed to the usual 1 in 8192 chance.
The Masuda method is a Japanese breeding technique used to increase the chance of obtaining a Pokémon with a foreign regional variant. The method named after Shigeki Masuda, the director of the Pokémon games Pokémon Diamond and Pearl, and Pokémon Platinum. It was first introduced in Pokémon Ruby and Sapphire.
The Masuda Method is a great way to get ultra sun services. It is quick, easy, and efficient. I highly recommend it to anyone looking for a great way to get their sun services.
