Long team rate incoming
As stall_fest said, mixed zard isn't that good. I'd suggest Air Slash or Hurricane over Fly, and since it's G-max, you could run Solar Beam over Earthquake since Power Herb can make it one turn as well. Honestly though, I think you should run Life Orb, especially for G-max Zard. tl:dr,

Timid Nature
IVs: 0 Atk
- Fire Blast
- Air Slash

Alcremie's physical attack isn't as good as it's special attack. I think Alcremie should be used as a more defensive set with Calm Mind, Recover, Dazzling Gleam, and Mystical Fire. tl:dr,

Flapple is better in most cases than Appletun, but if you use Appletun, don't run mixed sets. tl:dr, replace appletun with flapple.

Don't use special Machamp. Metronome won't work when G-maxed, also.

Butterfree is not really a good gmax in general, but a set that can work in base form and is pretty trolly can be...
