The Demoman excels at swift destruction; he can launch grenades and stickybombs at creative angles to wreak havoc on enemy encampments and Sentry Guns while remaining out of the line of fire, or simply blast his enemies into a red mist with a seemingly-endless stream of these explosives. His stickybombs are also a perfect tool for area denial, and are effective at keeping opponents away from carts, control points, Intelligence, or any other location he deems off-limits.

Only Muk can Sitting Cutie.

Now that is damn true.

In UU, Muk is very hard to beat if you don't know the set. I recommend Muk for any UU team. It also has a very high cool factor.

Standard

Muk @ Leftovers
Ability: Sticky Hold
EVs: 252 HP / 252 Atk / 4 SpD
Brave Nature
- Sludge Bomb
- Ice Punch
- Explosion
- Hidden Power Ghost

Use this set for Muk in UU, where it's right at home. Switch in on a Grasser or a Fighter (hopefully without Earthquake), and hit away. Ice Punch shuts down any unsuspecting Gligar, Hidden Power Ghost is for Misdreavus and Shedinja, and Hidden Power Grass stops Quagsire. There's no need for Special Attack EVs as you need more EVs in Special Attack than it's worth to OHKO either Gligar or Quagsire. Both Hidden Powers should do the job should Solrock come in to counter you.

I'm going chimp_criminal here.

Only Bad Luck can defeat Brian.
