Psyspam Team

First, your team is just psyspam, probably when the enemy has a pokemon like Kingambit, its hard to kill him. Probably removing 1 of the psychic pokemons is a good choice, you still have a psyspam and have other types of damage. On Team Type Coverage of Team Builder, your team doesn't have effective damage on most common types like fire, flying, etc. Maybe change a move set to improve that its another possibility. About the matchups when you lose, try to identify the reason, like a specific enemy pokemon or something like that. Do you have problems in specific matchups?
