Ability: Guts
EVs: 252 HP/16 Atk/232 Def/8 Spd
Adamant nature (+Atk, -SAtk)
- Low Kick / Cross Chop / Close Combat

For this machamp, revenge should be listed as an option since it has the ability to be powered up if machamp moves last or something like that.
Other sleep talk entry hazard abusers:
Aerodactyl; Item - leftovers/babiri berry
Jolly or Timid nature
252 HP / 4 Special Defense / 252 Speed
Rest
Skeep Talk
Whirlwind
Roar
130 base speed, 2/3 chance at a neutral priority switch phazing move, and good special defensive capabilites if used with sandstorm. The only problem with this set is scizor so babiri berry is viable for weakening bullet punch to a possible not OHKO.
Drapion; item - black sludge
Jolly or Timid nature
252 HP / 4 Defense / 252 Speed
Rest
Sleep Talk
Whirlwind
Roar
Same principle as the aerodactyl, set up some entry hazards and go to town. This one has more problems with fast taunters and dugtrio so paralysis support or azumarill recommended for teammate capabilities.
Cresselia; Item - Flame Orb or Toxic Orb
Timid nature or Calm/Bold nature
Timid - 252 HP / 208 Defense or Special Defense / 48 Speed
Calm/Bold - 252 HP / 192 Defense or Special Defense / 64 Speed
Rest
Sleep Talk
Psycho Shift
Trick
This one is a fun set and is built around status spreading. Spread the burn to incoming physical attackers through trick or psycho shift or put sleep on opponents if psycho shift is selected by sleep talk. Recovery is something cresselia needs, and the EVs given outspeed Jolly and Adamant tyranitar respectively so it can be burned before it crunches or pursuits cresselia to death.
There's more I'm forgetting but meh. Comments are welcomed for help on these few sets.
