Muk has probably one of the worst cases of four moveslot syndrome in history. His Poison typing and STAB are rather pitiful; Steel-, Rock-, and Ground-type Pokemon are three omnipresent types in UU and none of them mind it. This means Muk must rely on his big movepool to hurt switch-ins, but the limit of three leftover moveslots hinders him greatly. Explosion is also such a tempting move that it sometimes leaves Muk with only two moves to make up for his bad STAB. His movepool problems aside, Muk is an excellent special tank who can take attacks from the likes of specially oriented Venusaur and Lanturn. Muk's awesome 105 base Attack should not be ignored either, as it allows him to tear massive holes in foes that don't resist his powerful Gunk Shots. Muk may seem lackluster, but he can effectively fill in a variety of roles for your team.

252 HP / 80 Def / 176 SpD

Muk makes a fantastic Curse user in UU due to his superb special bulk and naturally high Attack stat. Unlike other Curse users, Muk is not susceptible to Trick thanks to his ability, Sticky Hold. This allows Muk to set up Curses on common Trick users, such as Clefable and Rotom, with little fear. Poison Jab is Muk's obligatory STAB move, while the third slot gives him better coverage. Brick Break allows him to damage Steel- and Rock-types such as Steelix, Registeel, and Aggron, which usually carry Earthquake to wreck Muk's set-up. Ice Punch allows Muk to hit Ground-types which normally switch in on it, such as Nidoking, Nidoqueen, and Claydol. For the last slot, Explosion is a powerful move that lets Muk takes out at least one last Pokemon, while Shadow Sneak allows him to hit faster Pokemon such as Espeon and Alakazam, which can threaten him with a STAB Psychic attack. Rest is another option if Muk has a couple of Curses under his belt since it allows him to replenish lost health and cure status. Gunk Shot is another option on this set for a stronger STAB attack, but it is not recommended because of its low PP and accuracy.

Choice Band

Choice Band Sticky Hold Adamant
Moveset EVs
~ Poison Jab / Gunk Shot
~ Brick Break / Focus Punch
~ Ice Punch
~ Explosion
252 HP / 252 Atk / 4 SpD

With an impressive base 105 Attack and high defensive stats, Muk can effectively utilize a Choice Band set. STAB Gunk Shot can deal a considerable amount of damage to Pokemon that do not resist it; however, Poison Jab is the safer option due to its higher accuracy. The selection between Brick Break and Focus Punch solely relies on your prediction skills. Focus Punch deals much more damage overall; for example, it deals 62.15% - 73.45% to Relaxed 252/0 Steelix, Muk’s number one counter. Brick Break will fail to get a clean 2HKO on Steelix, but is a much more reliable option otherwise. Ice Punch deals with Grass- and Ground-types like Venusaur, Torterra, Nidoking, Donphan, and Claydol. In the last slot, Explosion is a powerful attack that literally OHKOes any UU Pokemon that does not resist it. Payback is another option in place of Ice Punch to hurt opposing Psychic-types, but Ice Punch is preferred, as it damages Ground-types who can hit Muk on his lower Defense stat with Earthquake.

~ Substitute
~ Focus Punch

~ Ice Punch / Payback / Explosion
212 HP / 252 Atk / 40 Def / 4 Spe

With Substitute, Muk can utilize the jaw-breaking Focus Punch to more easily smash through opposing Steel- and Rock-types. This set is quite simple to use: set up a Substitute on a Pokemon whom Muk will scare out, and then use Focus Punch if it can hit super effectively. Poison Jab is the preferred STAB attack and is Muk's most consistent form of dealing damage; however, Gunk Shot offers more power and Muk has extra time to fire it off from behind a Substitute. Ice Punch covers Grass- and Ground-types like Venusaur, Nidoking, and Donphan who resist Fighting and/or Poison. Since Muk can only achieve a 3HKO at best on these Pokemon, you may prefer Payback to maim Ghost- and Psychic-types instead. As always, Explosion is an option in the last slot to allow Muk to go out with a bang.

~ Pain Split / Explosion
252 HP / 68 Atk / 188 SpD

This set plays a little more differently than the sets above. Its aim is to handle special attacks directed at Muk while dishing out attacks with his impressive base 105 Attack. Poison Jab is the preferred move for better accuracy, while Gunk Shot provides extra power but less accuracy. Unlike the previous sets, this one does not mind the PP drop from choosing Gunk Shot. Brick Break and Focus Punch are a must to damage opposing Rock- and Steel-types who would otherwise wall Muk completely. Ice Punch is useful against opposing Ground-types and Venusaur who attempt to come in on a Poison- or Fighting-type attack. Payback is another option for hitting opposing Psychic-types who could be problematic for Muk. Pain Split is the main option for decent recovery; it can also help do significant damage to Pokemon such as Registeel if Muk is at low health and they are at high health. Explosion is another option for this set as a last ditch effort to take out an opposing bulky Pokemon, such as Hariyama or Azumarill. Giga Drain can surprise and eliminate Rhyperior, Omastar, and Kabutops on the switch, but those are the only significant targets in UU. If you decide to use Giga Drain, then a Brave nature is recommended to maximize Giga Drain's power by not lowering Muk's Special Attack. Shadow Sneak is another option on this set to cover speedy Psychic-types, but it is far too weak without a Curse boost. Fire Blast can also be used to hit Steelix on its weaker Special Defense stat, but that is the extent of its use.

Other Options

Besides Ice Punch, Muk also has access to ThunderPunch and Fire Punch. ThunderPunch can strike down Qwilfish, Moltres, and Scyther, while Fire Punch can roast Venusaur, Heracross, and Torterra. Memento is an extremely unorthodox move that Muk can employ in some very circumstantial cases to set up your next Pokemon, but this role is usually better done by faster Pokemon that can also set up dual screens (e.g. Uxie). Mean Look can force something to stay on the battlefield so Muk can Explode on them. Muk can also perform Haze, but Weezing usually does a better job at doing that thanks to his higher Defense stat and immunity to Earthquake. Taunt is decent since it stops Pokemon from setting up and forces Ghosts to attack so Muk can hit them with Payback while also preventing them from burning Muk. However, Muk is usually too slow to utilize Taunt effectively. Screech can force a switch, which sometimes allows Muk to fire off a free Focus Punch.

Checks and Counters

Muk has a plethora of counters in UU. As mentioned in every set, Muk has a difficult time dealing with most bulky Steel-, Rock-, and Ground-types, which are all very common defensive types in UU. Steelix and Registeel in particular can prevent Muk from doing anything because of their titanic Defense stats. Muk’s only way of damaging them is a boosted Focus Punch, but it is unreliable. Nidoking, Claydol, and Nidoqueen are also troublesome to Muk because they resist Muk's STAB and Fighting-type moves. Furthermore, all three have a considerable amount of bulk to take an Ice Punch, outpace Muk, and dispose of him with their STAB Earthquake. Drapion is also another forgotten threat who can set up Swords Dance and scare away Muk with Earthquake.
