Best nature for a Mudkip?

[hibu_tan]

So, i've been breeding a ton of mudkips via masuda method. Trying to get a shiny,
but the main thing is
what nature would be best for a mudkip so I can give the everstone when I hatch one w/ that nature that has good ivs.

i've been wondertrading all the excess mudkips that aren't shiny,
but if any of ya'll want one lemme know, they're nonshiny w/ 4-5ivs
i just wondertrade them anyway haha.

Personally an Adamant natured Mudkip would get you somewhere since Swampert has a good physical movepool and has a much higher Attack base stat than special attack.

I'm not planning on evolving up my mudkip, but I also want to give a good nature for the people that recieve them on wonder trade that are going to evolve them ;v ;
I think adamant would be good for that too, but I just wanted to get a second opinion as I'm new to pokemon breeding and all that stuff.
So, thank you!
