Hey I have a team with azumarill mamoswine volcarona miltank and breloom..

I finally found all of the 7 sages but I can't find ghetisis does anyone know where he is and how to get to him

Try this team

Mamoswine:(Ice Beam, Earthquake, Ancientpower, Toxic)
Ice Beam is for Dragons, Flying,Ground, and Grass. Earthquake is for Steel, Rock, Poison, Ice, and Electric.
Ancient Power is for Flying and it's stat increase.
Toxic is for poisoning the opponent in case of a stall

Volcanora:(Signal Beam, Quiver Dance, Hyper Beam, Heat Wave)
Signal Beam is for Psychics, Dark and Grass.
Quiver Dance is for stat boost.
Hyper Beam is for a power blast.
Heat Wave is for Grass, Bug, Ice, and Steel.

Breloom:(Leech Seed, Stun Spore, Sky Uppercut, Giga Drain)
Leech Seed is to be combo with Giga Drain. This will be a spam healer. Also with Giga Drain and Leech Seed is good for Rock, Ground, and Water.
Stun Spore is good for not just wild Pokemon but also to help freeze the opponent in his tracks.
Sky Uppercut is good for Normal, Steel, Dark and Rock.

Porygon 2:(Lock On, Zap Cannon, Hyper Beam, Recover)
Recover is for healing spam.
Lock On and Zap Cannon is a combo that is good for Water, Normal, Flying or any other Pokemon with low Sp.Defense(assuming if it has no resistances)

I would switch Azumirral and Miltank for these Pokemon.

Crobat:(Fly, Crunch, Poison Fang, and Mean Look)
Mean Look is so if the opponent is confused and Leech Seeded, they can not switch out.(also good for roaming)
Poison Fang is good for Grass.
Crunch is good for Psychic and Ghost(also flinch).
Fly is good for Bug and Grass.

Sableye:(Mean Look, Embargo, Attract, and Thief)
Sableye will be used to spam status effects. So start with Mean Look. Then add Attract, then finally use Embargo to keep it from both attacking and item using. Also Thief will steal items if needed.

This is a good team using 4 out of the 6 Pokemon you listed. Also this team covers any weakness your opponent has and with status effects to spare. Between the attacks of your Pokemon and the status effects there should be no reason to worry about your own weaknesses.
