Level 100 Statistics (see level 5, 50, 100)
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.
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.
Slow and over 404 HP, so Muk is automatically a great Subpuncher. With a great Attack, this is something to watch out for. In UU, the only Steel that is used sometimes is Mawile, which Focus Punch is more than enough for, so Fire Blast isn't needed.
Great Special Defense and Attack like Snorlax, Muk makes a pretty good Curser. Cursed Explosion is powerful, but with Rest you can keep on tanking. It will probably be run over by Psychic and Earthquake.
More novelty than anything. Bring it in like you normally would, and predict what your opponent is going to do. Use the right attack, and hopefully you will hit them hard.
When you are running no special attacks, at least 401 HP on Muk, 404 if you are using Substitute. Adamant for the SubPuncher, Careful for the Curser, with EVs focused on the stats you are boosting (Attack and Special Defense respectively).
For mixed movesets, use a speed-cutting nature: Brave for more Attack, Sassy for more Special Defense.
As you see, Muk is quite hard to spread EVs for, so if you're having a lot of trouble you can just use max HP and Attack and you'll be just fine.
Body Slam can paralyze the opponent, and paralysis is always good. Imprison is very unorthodox and works in very rare circumstances, stay away from it until you've tried out the standard Muk. Memento can make your opponent's Pokémon harmless, so you can set up a Belly Drummer next turn. Explosion is more recommended for suicide, though. Rest, with or without Sleep Talk, makes your Muk live longer. It's really an easy switch for counters though.
Checks and Counters
Muk is hard to counter. Its first set isn't shut down by anything completely, except Misdreavus and Shedinja if you run Hidden Power Grass, or Quagsire / Whiscash if you have Hidden Power Ghost. Nidoking and Nidoqueen can take one or two Ice Punches and Earthquake Muk to death.
