1)Take psychic off of Kyurem it's a physical attacker and psychic isn't that powerful on him.
2)Give Trevenant Rapid spin over confuse Ray It's more useful
3)I personally think you should switch Electivire with something else possibly Garchomp
4)I think you should switch Ninjask with Scolipede because scolipede can do the same thing Ninjask can but better
Other than those few things the team looks pretty good
