Well here is my favorite Pokemon of Generation 3.
Name: Shedinja
Ability: Wonder Guard [Its ability wouldn't and shouldn't change in Dream World. The fact that it does not change in between worlds is actually a good thing, considering that I was worried about that the most when imagining Shedinja in combat, especially Ubers]

TM 06 Toxic
TM 10 Hidden Power
TM 11 Sunny Day

Hmph, so far so... okay. My only issue is Shedinja not learning Dragon Claw yet. =/ (or Agility! -.-')
Anyway, let's assert a set for my good ol' Hoenn friend here.
Set 1: The Lonely Guardian
Shedinja @ Focus Sash
EV Spread: 255 Atk, 255 Spe
Ability: Wonder Guard
Nature: Lonely
Moveset:
1. Claw Sharpen [Dark]
2. Shadow Sneak [Ghost]
3. Dig [Ground] / Baton Pass [Normal]
4. X-Scissor [Bug]
Reasons behind Movepool:
1. Claw Sharpen raises Attack AND Accuracy. It's already better than Swords Dance, and is cool considering Shedinja can't afford to miss against other Pokemon in Ubers.
2. Shadow Sneak is for priority and STAB. It has to go first against Ghost-types or else it will be toast.
3a. Shedinja cannot afford to die so quickly. Dig acts as a pseudo-proctect and will damage the next turn unless the opponent has the Ability Levitate or is a Flying-type. And in Dream World...
3b. Baton Pass the Claw Sharpen (or the Dutch) up on the left hand side, and other Pokemon will definitely feel grateful for him.
4. X-Scissor is another STAB move that Shedinja can use.
It hasn't changed all too much, but Claw Sharpen and Life Gamble help it a little. With Stealth Rock not a TM, we'll definitely be seeing a lot more of this awesome guy around in Ubers/UU/BL battles, hopefully. Maybe not OU...
Base Stats:
HP - 1
Atk - 90
Def - 45
SpAtk - 30
SpDef - 30
Speed - 40
EDIT: Yeah, I got it. Life Gamble is stupid on Shedinja...
