Dude you have a lot of pokemon i like and use quite frequently. So i'll give you the sets my pokemon have and you could try them. they work pretty well.
Hitmontop (M) @ life orb
Role: Physical Sweeper
EVs: 252 sp.def , 252 attack , 4 hp
Ability: technician
Adamant Nature
Fake out
Mach Punch
Aerial Ace
Sucker Punch
all his moves get boosted by technician except sucker punch. Hitmontop can take down a lot of weaken pokemon. It even defeats conkulder. nobody really sees this so they dont expect the ariael ace.
Bisharp (M) @ Dark Gem
Role: Physical Attacker
EVs: 252 Atk, 252 hp , 4 Def
Ability: Defiant
Adamant Nature
Thunder Wave
Swords Dance
Sucker Punch
Iron Head
I love this thing!! You have to combos to go with. 1st you can t-wave and then iron head away. but what i mainly do is set up a sword dance if i can and sucker punch away, with dark gem, it almost okos everything that isnt resisted by it, but if they predict the sucker punch you can t-wave then iron head or just go for the iron head. you'll be guaranted atleast two pokemon taken care of ;)
Crobat (F) @ black sludge
Role: Staller/physical attacker
EVs: 252 Speed . 252 attck, 4 SpDef
Ability: Inner Focus
Adamant Nature
Brave Bird
u-turn
protect
confuse ray
this doesnt look very promising but beleive me it is. I decided to use this crobat because i got swept by it once, and i decided i must have it, so i built it. it works really really well. you can brave bird and then heal up with black sludge and protect. if a pokemon completly walls you than you can u-turn away. and confuse ray with protect is awesome or you can just u-turn and hope for a confusion hit and get a free switch.
Mismagius (F) @ focus sash
Role: special attacker/ set up helper
EVs: 252 speed, 252 Sp.atk, 4 Sp.def
Ability: Levitate
Timid Nature
Icy wind
Thunder bolt
Hidden Power [Fire]
Mememto/destiny bond
most things are 2 hits to build killed by this thing. but the main plan is to icy wind to guarantee they'll be slower and then you can use memento to weaken it and then set up with one of your pokemons or guarantee one of their pokemon to go down. icy wind also helps with gliscor and dragons and hidden power is for the obvious ones.
