I am going to make a slightly different T-room team.

Item: Leftovers
Nature: Quiet
Ability: Mummy
EVs: 252 S.attack, 200 S.def, 58 Def
Trick-room: The whole point
Shadow-ball: STAB
Psychic: Coverage
HP(Fire): Coverage
This guy is my lead and as such he is bulky, sets up T-room, and can take care of common leads which is why I have HP(Fire) to remove: Ferrothorn, Foretress, and Skarmory etc.

Item: Focus-sash
Nature: Brave
Ability: Solid-rock
EVs: 252 Attack, 252 Hp
E-quake: STAB
Stone-edge: STAB
Fire-punch: Coverage over Grass and Ice
Thunder-punch: Covers Water
This guy is a Rampardos replacement on this team with lower attack and highier defense. Focus-sash protects you from one hit from a special attack.

Item: Leftovers
Nature: Quiet
Ability: Snow-cloak
EVs: 252 S.attack, 128 def, 128 S.def
Ice-beam: STAB
Shadow-ball: Coverage
HP(Ground): Coverage
Wish: Helps to heal a T-roomer in case of an emergency
My main Special Sweeper with a 394 Special attack there will be damage dealt ALOT of it. He also serves purpose as a wish passer.

Item: Leftovers
Nature: Quiet
Ability: Trace
EVs: 252 S.attack, 200 Def, 58 Hp
Trick-room: Obviously
Psyshock: STAB
Thunderbolt: Coverage
HP(Ice): Coverage
I needed another Special attacking T-room user so Gardevoir was a natural choice. She has a mini-bolt beam because I already have 2 Pokemon with Shadow ball I don't need it.

Item: Macho-brace/Iron-ball
Nature: Brave
Ability: Sap-sipper
EVs: 252 attack, 252 hp, 6 def
Trick-room: Obviously
Return: STAB
Mega-horn: Coverage
Zen-headbutt: Coverage
Everyone uses Dusknoir as their Physical Trick room activator and for good reason but I already have a ghost type and am trying to mix it up a bit so... Stantler is an amazing Grass type counter for whatever grass is not weak to mega-horn is probably weak to Zen-headbutt(Only Ferrothorn is not weak to it). I am willing to switch this guy for something else though.

Item: Occa-berry
Nature: Brave
Ability: Technition
EVs: 252 Attack, 200 Def, 58 S.def
Bullet-Punch: STAB priority coming off a 394 attack stat..scary..
Brick-break: Coverage
Bug-bite: STAB and When your done with your berry take another
Swords-dance/Aerial ace: Cant decide help please. Boosting or Coverage
This is the guy I can use both when T-room is on and off because of Bullet punch.
Can I have some suggestions?
