AC, I have been thinking about this and I think I have a solution. Escavalier and Dusknoir.
Escavalier @ Leftovers
Trait: Swarm
Nature: Adamant
EV spread: 252 Atk, 150 HP, 202 Defense
Moveset:
- Protect
- Megahorn
- Iron Head
- Sword Dance
Dusknoir @ Lum Berry
Trait: Pressure
Nature: Bold
EV spread: 252 Defense, 252 Special Defense, 4 HP
Moveset:
- Trick room
- Will-O-Wisp
- Shadow sneak
- Earthquake
Since you have battled me countless times you probably already know what is coming next. On the first turn you use protect on Escavalier and and trick room. Escavalier can't be put to sleep due to protect and Dusknoir can't flinch due to it's immunity to normal. Even If the foe's Breloom uses spore on Dusknoir, it will recover due to it's Lum berry. Under Trick room it Escavalier can take out Liepard, Breloom ( I recommend Breloom because you wouldn't want to be under spore). After Breloom taken out Liepard would be in trouble. It would only have two possibilities:
1. Use foul play on Escavlier and do massive damage
2. Use swagger on Dusknoir and afterwards spam foul play
3. Use substitute, then swagger and afterwards spam foul play.
The latter one would be a problem but using shadow sneak would immediately get it out of it's substitute and then you could hit hard with a stab Megahorn
Hope this helped

This is another option
Garchomp @ Lum berry
Trait: Rough skin
Nature: Jolly
EV spread: 252 Atk, 252 Spe
Moveset:
- Outrage
- Fire fang
- Earthquake
- Rock slide
Spiritomb @ Lava cookie
Trait: Infiltrator
Nature: Adamant
EV spread: 248 HP, 252 Attack, 8 Sp. defense
Moveset:
- Sucker Punch
- Shadow sneak
- Trick
- Will-O-Wisp
The first moves are pretty simple. Because Garchomp has high attack stat Liepard would probably use swagger on it. What the foe doesn't usually expect is Garchomp holding a lum berry. With it's attack stat being powered up it uses Outrage and liepard is taken down. Breloom goes with spore on Spiritomb. Waking up with lava cookie it uses Will-O-Wisp. When the next turn begins Garchomp uses a stab outrage OHKOing or nearly OHKOing Breloom. If it survives the turn it will probably be taken out by it's burn
This is also an option
Rotom-S @ Choice specs
Trait: Levitate
Nature: Timid
EV spread:4 Defense, 252 SpAtk ,252 Spe
Moveset:
- Volt Switch
- Trick
- Air Slash
- Hidden Power( Fighting)
Crobat @ Flying Gem
Trait: Inner Focus
Nature: Jolly
EV spread: 252 Atk, 252 Spe, 4 HP
Moveset:
- Acrobatics
- Taunt
- Tailwind
- Brave Bird
Even though it looks a little obvious what this pair is going to do I will explain anyway. Firstly Rotom-S uses Trick and tricks Liepard into using one move, this will probably be Foul Play or Swagger. Then using acrobatics or brave bird to take out Breloom you don't have to deal with spore spam. Now that Liepard is stuck in one move you can take it down in all peace and serenity. But don't overreact because after all , liepard are very sly.
This is going to be one of my last suggestions:
Infernape @ Lum berry
Trait: Iron Fist
Nature: Jolly
EV spread: 252 Atk, 252 Spe, 4 Defense
Moveset:
- Mach Punch
- Thunder Punch
- Fire Punch
- Close Combat
Hitmontop @ Leftovers
Trait: Intimidate
Nature: Adamant
EV spread: 252 HP, 126 Atk, 126 Defense
Moveset:
- Quick Guard
- Close combat
- Taunt
- Rock Slide
Ok, this one is very simple. You firstly use Quick Guard to prevent fake out from being used. Then you just commence with sweeping that team. Using Mach punch on Liepard and the job is done. Getting rid of Breloom won't be a problem too.
I will keep adding more
