Dexnav and hidden abilities

So I’m after a excadrill with mold breaker, and I’ve got conflicting sources on getting hidden abilities, both of which are old posts. So can I get what I want from dexnav, or only from friend safaris and dream mist? And if I can get it from dexnav what are the rates?

I think it’s possible with dexnav but I’m pretty sure the odds are the same as wild encounters. I could jive you a jolly mod breaker if you want though.

I’m also doing a professor oak challenge and trades are against the rules. I can always get one myself later on, I’ll most certainly have the resources for it.

It’s not possible from wild encounters. Nor from DexNav.

Really? That’s kinda dumb but whatever

I guess that’s that then.
