Dedenne isn't a strong Pokemon but I was wondering how to get one with a beneficial nature if possible so it cket hold its own in battle
There is always friend safarai witch will always grant 3iv's or more
and there is also breeding witch can give you egg moves natures iv's and ev's and shinies
with some effort put into it.
Hope I helped
The best natures would either Timid or Modest both decrease Attack, but I recommend Timid as it boosts Speed as it is its highest Stat.
Hope I Helped
Friend safari gives you decent Pokemon, talking about that, I have a dedenne in my friend safari.
