Is there a particular Pokemon in your battling team you feel like you've "mastered"? Meaning to say, you've gotten a firm grasp on how to play it effectively, using the Pokemon's full potential in a battle.

Pic related. I've pretty much mastered Volcarona that I can not hesitate to either set up, tank a SE hit and KO after etc. I've built my entire team around its sweep and I think any future team I have will include Volca.
