Third Rotation Team suggestions

[CoronelEmpoleon]

Currently I have 2  teams and I am building the third right now but i am not sure about the pokemons on the team yet, if possible i want to leave the members from team 1 and 2 out of the third team so I will briefly mention them:

Main Team:
Azumarill
Blaziken
Honchkrow
Magnezone
Mamoswine
Reuniclus

Secondary Team:
Garchomp
Metagross
Greninja
Chandelure
Galvantula
Togegiss

Now following below are the 6 possible members, I am open to suggestions on weather to switch any of them for other pokemons or anything related to their individual builds(Moves. EV spread,abilities etc)
Gliscor
Arcanine/Darmanitan
Rotom Wash
Venusaur/Amoongus/Roserade/Or another viable grass pokemon
Clefable/some other fairy type perhaps Mimikyu
Aegislash

PS: I would also appreciate if you guys could suggest builds for the second team mons
