1 sunny day setter might not be enough
And camouflage? o_O

I replaced Gabite with Probopass a mix wall utility pokemon.
I replaced Sawbuck's camouflage with aromatherapy. I Sashed, Huntail, I expert belt Gardevoir (I took down slaking after taking down the other probopass thanks to sturdy!) And for Charizards new move set-Solar Beam, Giga Impact, HP Electric, and flamethrower.

I'd change aromatherapy to nature power since in wifi battles it becomes the equivalent of Earthquake. Change Charizards moveset to Sunny Day/Fire Blast/Solarbeam/Roost with heat rock
Or use Fire blast/air slash/roost/focus blast or substitute with life orb
Giga Impact is useless, the only pokemon I'd think running it with would be slaking
