I don't pretend to be an expert with Heracross, Sir Chris would be better for this, but anyhoo: I would have Brick Break over Focus Punch, becase you don't seem to have a way to debilitate your enemy appropiately on your entire team. Unless that's as a Slaking killler...
EVs are good for Choice Banded Hera.

Item: Leftovers

-Surf
-Rest
-Toxic
-Leech Seed
The general concensus with Ludi here is Swift Swim>Rain Dish. If you want Ludi as primarily a water type, try this set:
Rain Dance
Surf
Leech Seed
Rest

Item: Leftovers
Trait: Clear Body
Personality: Sassy
EVs: 252/0/252/0/0/4
-Rest
-Toxic
-Earthquake
-Thunderbolt
There were some good Registeel sets floating around her a few months ago, unfortunately i can't remember any.
I think Safeguard over Rest would be a good investment here, but use your own judgement. (Remember Registeel cannot be poisoned.)

Item: Lum Berry
Trait: Synchronize
Personality: Timid
EVs: 4/0/0/252/252/0
-Psychic
-Calm Mind
-Fire Punch
-Thunder Punch
Try Knock Off over Thunderpunch, taking all those leftovers off your opponents team will be a real bonus, plus it give you a chance to royally skrew up other Choice Banded Heracross before you die.

Myself I like this Swmpert:
@Lefties
Personality: Quiet (+ SpAtt -Speed)
Curse
Roar
Earthquake
Ice Beam
Curse Roaring is great, and thus you'll also want a - Speed nature. I gave it Quiet for Ice Beam. Also with Ice Beam you have a chance of catching some Grass types on the switch in, plus nothing can resist the Ice/Ground attack combo.
...Actually I think this is Ralts_Mudkip's Swampert
no wonder it sounded familiar.

Item: Leftovers
Trait: Pressure
Personality: Careful
EVs: 252/0/128/0/0/128
-Rest
-Protect
-Night Shade
-Will-O-Wisp
[B]Good EVs, but try this set:
Mean Look
Toxic
Curse/Night Shade
Rest
The idea behind the Curse set is: Trap the enemy, poison 'em, curse 'em, and then get some rest and sit around while it kills itself. The problem here is that Dusclops will get owned by pokes with Tuant, that's why it's worth considering Night Shade over Curse. The choice is up to you.
