So after slogging through the Kangaskhanite tiering thread, I saw a strategy using multiple Healing Wishes to bring M-Kangaskhan back from near-death, so I stole it and tried it myself. It is the most flat-out broken thing ever (as if Kang by itself wasn't broken enough!!) - after your opponent jumps through hoops to try to at least neutralise SCP-682's spawn, let alone be near killing it, you can send out something like Jirachi and not only bring it to full health, but remove all status. My take on it:
Kangaskhan @ Kangaskhanite
Nature: Adamant
Trait: Scrappy
4 HP / 252 Atk / 252 Spe
- Power-up Punch
- Return / Body Slam
- Sucker Punch
- Crunch / Fire Punch
Gardevoir @ Light Clay
Nature: Timid
Trait: Trace
252 HP / 4 SAtk / 252 Spe
- Reflect
- Light Screen
- Moonblast
- Healing Wish
Jirachi @ Choice Scarf
Nature: Timid
Trait: Serene Grace
252 Atk / 4 SpD / 252 Spe
- Iron Head
- Ice Punch
- Fire Punch
- Healing Wish
Use Gardevoir to set up screens and check fighting-types and Jirachi to check faster things that can KO a weakened Kangaskhan. When your Healing Wish mons are near-done, use Healing Wish and Kang, even when in red-health and burned, will be in tip-top health to rip apart the opposite team a second or even third time. You can feel the despair of your opponent through your screen as this happens, and many times, they'll simply forfeit. You can also use other mons like Latias and Cresselia (Lunar Dance) equally well. Quite conveniently, most Healing Wish users are Psychic and/or Fairy, resisting Kang's only weakness, and Kangaskhan resists their Ghost weakness. Throw in something like Talonflame or Rotom-H and you're good to go.
