This combo focuses on confusing, putting to sleep, and paralyzing your opponent while you mercilessly lower his/her HP.  First let's take a look at the cards:
 
Snorlax- 90 HP
 
Pokemon Power: Snorlax cannot become asleep, confused, paralyzed, or poisoned.  This power stops working while Snorlax is asleep, confused, or paralyzed.
 
Body Slam CCCC (30) Flip a coin.  If heads, the Defending Pokemon is now paralyzed.
----------------------
Dark Gloom- 50 HP
 
Pokemon Power: Once during your turn, you may flip a coin.  If heads, the Defending Pokemon is now confused, if tails, your Active Pokemon is now confused.  This power can't be used is Dark Gloom is asleep, confused, or paralyzed.
 
Poisonpowder GG (10)  The Defending Pokemon is now poisoned.
--------------------
Drowzee (Rocket)- 50 HP
 
Pokemon Power: Once during your turn, you may flip a coin.  If heads, the Defending Pokemon is now asleep, if tails, your Active Pokemon is now asleep.  This power can't be used is Drowzee is asleep, confused, or paralyzed.
 
Nightmare PC (10)- The Defending Pokemon is now asleep.
---------------------
Ok, if you haven't already figured it out, this combo relies on promoting Snorlax as your Active Pokemon, and keeping a lot of Drowzees and Dark Glooms on the Bench.  You keep flipping until the opponent is asleep or confused, and then use Snorlax's Body Slam.  If you're lucky, your opponent will be paralyzed, and even if he's not, he'll still have a hard time attacking because of the confusion or sleep.  In addition, the opponent may be previously affected from poison from Dark Gloom or an Oddish.  Here's a deck that focuses around this combo:
 
Pokemon (17):
4 Snorlax
4 Oddish (Rocket)
3 Dark Gloom
4 Drowzee (Rocket)
2 Ditto (The all-purpose Ditto.  I never liked him much because he could be killed by a Gust of Wind, but I think he fills the Pokemon gap well in this deck.)
 
Energy (26):
4 DCE
4 Full Heal Energy (nice if Dark Gloom or Drowzee is your Active Pokemon and you want to use one of their Pokemon Powers.  Won't hurt the Energy distribution because Snorlax requires a lot of Colorless, and Drowzee requires one too.)
 
10 Grass Energy
8 Psychic Energy
 
Trainers (17):
 
3 Professor Oak
3 Bill
2 Lass (All the DCE will be weak to Energy Removals, so you might want to shell one of these out when playing DCE.)
3 Switch (With a 4 Energy retreat cost, Snorlax will need some help.)
3 Pokemon Trader (There are many different types of Pokemon in this deck, while all working together, you may want a certain one for maximum effectiveness.)
3 Gust of Wind

This combo is very powerfull and could create a whole new archetype.  I haven't tried it out yet, but I'm sure many of you will and I hope to see some Killer Reports soon.
