So another one of my random thought dump posts: Evolite edition
Dunsparce: with an evolite looks really solid. It is considerably bulkier then Dudunsparce and reaches levels of bulk not really seen on a normal type outside of chansey. The lack of offensive potential will limit it quite a bit but its movepool can still compliment this primarily defensive role fairly nicely. Specifically because of serene grace shenanigans, but he can also act as a menace with hazards, paraflinching, and yawn.
Some quick examples:
252 Atk Garchomp Earthquake vs. +1 252 HP / 252+ Def Dunsparce: 99-117 (24.5 - 28.9%) -- 99.4% chance to 4HKO
252 Atk Garchomp Earthquake vs. +1 252 HP / 0 Def Dunsparce: 147-174 (36.3 - 43%) -- guaranteed 3HKO
252 Atk Life Orb Lucario Close Combat vs. +1 252 HP / 252+ Def Dunsparce: 273-322 (67.5 - 79.7%) -- guaranteed 2HKO
252 SpA Gardevoir Focus Blast vs. +1 252 HP / 0 SpD Dunsparce: 242-286 (59.9 - 70.7%) -- guaranteed 2HKO
252 SpA Gardevoir Focus Blast vs. +1 252 HP / 252+ SpD Dunsparce: 160-190 (39.6 - 47%) -- guaranteed 3HKO
This bulk on either side with or without investment is pretty nutty.
Something dunsparce does not have that dudunsparce does have and its bizzare and cool? Tailwind of all things. So that's something to keep in mind.
If it can make you happier, I likely will, though it depends on... if I actually run into one with a usable nature first :P
I have the bad habit (developed from too much breeding I guess) of refusing to use Pokemon with detrimental natures during story. I'll be ok with suboptimal (es, neutral, or +atk - def for example), but I won't use something actively bad for the pokemon (like a -atk or -speed nature)
Inclement emerald specifically has tarnished my ability to use bad natures
