By ''using'' I mean in-game and wi-fi
I'd have to say... no. It is outclassed by other Psychic types, such as Alakazam, Reniculus, Espeon, Gardevoir, and Gothilele to name some of the more prominent.
Musharna has good hp and defences so you might want to use it as backup and support. What's great is it can also learn a good variety of moves. The choice depends on you.....
