Muk

Muk is one of the quintessential Poison Types, representing the type as a literal pile of living, toxic sludge. However, the fact that it's probably one of the first Pokemon that many people think of when thinking of a Poison type doesn't mean that it's good. Poison is one of the worst types in Pokemon Go, and Muk is pretty mediocre within the type. Honestly, it's not worth investing in poor Muk.

Best PvE Offensive Moveset

• Poison Jab and Gunk Shot makes up Muk's best moveset.
• Acid* falls behind Poison Jab by a bit and is legacy, while Acid Spray is just a poor move in PvE.
• Infestation, Lick*, Dark Pulse, Sludge Wave, and Thunder Punch all fall behind.

Best PvE Defensive Moveset

• Poison Jab has the highest power among Muk's Fast Moves when accounting for STAB, while Infestation has counter-coverage against Psychic Types.
• Dark Pulse hits opposing Psychic Types hard, while Thunder Punch comes out fast and frequently.
• Acid*, Lick*, Gunk Shot, Sludge Wave, and Acid Spray are all sub-par.

Poison Jab is recommended for its STAB damage output and above-average energy generation.

Thunder Punch is Muk's cheapest charge move energy-wise, and provides valuable coverage against common Water and Flying Pokemon. Dark Pulse features a balance between energy cost and damage output, and also provides coverage against Muk's weakness to Psychic-types. Acid Spray provides utility with its guaranteed -2 DEF debuff on the opponent, but it costs less energy to bait shields with Thunder Punch instead. Sludge Wave costs less energy than Gunk Shot if a high damaging charge move is needed, but Poison-type attacks aren't very valuable generally speaking.
