Last time I went to the Pokemon VGC I didn't encounter any taunting, so after I beat X I made a Musharna with both walls, Trick Room, and Toxic for my doubles team. I've been playing online matches and I still haven't been taunted even once yet, so it's working out very well (as long as I switch out when Gengar is around).
I'm curious though, should I be expecting a Taunt from someone who knows what they're doing? Just how common is the move in the competitive scene?
