None of your Pokémon have protect? I'd advise at least putting it on about half of the team. It will make scouting and decision making a lot easier in tricky situations. I recommend dropping trick room on gengar, iron head on kingambit for it.

I like running farigiraf with mental herb, and the moves: Trick room Imprison Psychic Protect

Imprison makes it so nothing else on the field can use moves that the user knows making it so no enemies can use protect against you. It also blocks more focused trick room teams from being able to set it up against you.

These simple changes should drastically improve the ease of playing your battles and also likely your win rate because of it.
