Espurr, especially a Female Espurr, does really well in-game due to its pretty decent good learnset that it gets. Its only issue is that it becomes outclassed by other mons with better stats such as Gardevoir or Alakazam.
Anyways, it is up to you to use it mate but I would say to try it out and have fun with it. That being said, give it Competitive if a Female or Prankster if a Male.
