Which nature is best for Shiny Shaymin?

[Brownstein350]

I have a relaxed Shiny Shaymin and a timid Shiny Shaymin. Which one is the best nature for Shiny Shaymin and if not these natures then what other natures are suited for Shiny Shaymin. Please let me know as soon as possible. Thank you.

Ideally a Shaymin should be Timid, however you can get away with Modest aswell

Timid is better
