Ok, Final team, no more changes

Elec the Helioisk
Aqua the Greninja
Bey the Baltoy
Gyro the Scizor
Onion the Breloom
Pyro the Talonflame

This team has extreme balance. perfect.
I'm assuming that it will be Greninja that will be mega evolving.

Yea, I thought it through, the types I need, the moves they can support, and their capabilities

Can my Baltoy still evolve?

yes. eventually.
