Wigglytuff's horrid defenses, low Speed, and massive HP stat create the perfect conditions for Wigglytuff to eat attacks and make use of Counter. Thanks to that gargantuan HP, nearly every attack Wigglytuff Counters is going to KO the foe right back. Luckily for Wigglytuff, while its horrid defenses mean it's usually 2HKOed by most Choice Band-boosted STAB moves, it usually isn't OHKOed unless it's a Fighting-type move, further increasing the use of Counter considering the large number of non-Fighting-type Choice Band users in the tier, including Graveler, Relicanth, and Pidgeot.

Wish and Protect allow Wigglytuff to survive throughout the match, support the team, and possibly even use Counter more than once. Protect also allows it to scout the moves of Choice Band attackers and react accordingly. Return is for a reliable STAB attack; however, Toxic can be used, as Wigglytuff is going to be utterly walled by Haunter and Steel-types anyway, and Wigglytuff can provide a defensive role by using Toxic to stall out certain weak attackers like Sableye and defensive Flareon.

An Impish nature ensures Wigglytuff can survive as many physical moves as possible and be able to hit back with Counter. With max HP investment, Wigglytuff's Counter is going to one-shot pretty much anything that doesn't OHKO it. While typically it would be better to invest in both defenses and leave Wigglytuff's HP alone, which will increase Wigglytuff's overall bulk significantly, investing fully in HP actually increases Wigglytuff's physical bulk significantly enough to allow it to avoid a 2HKO from Choice Band Sudowoodo's Double-Edge where it wouldn't otherwise.

If you check Wigglytuff's learnset, you'll notice how you can scroll for quite a while before reaching the bottom. There are a ton of moves that can be used in place of any of Wish, Protect, or the last slot depending on your team and what you want Wigglytuff to accomplish. Some good choices include strong damaging moves like Fire Blast, Blizzard, Focus Punch, Psychic, and Thunder to make use of Wigglytuff's decent attacking stats, a consistent move like Seismic Toss, support options like Safeguard, Reflect, Light Screen, Sunny Day, and Rain Dance, and other niche moves like Perish Song.

Having a switch-in to Hitmonchan's Fighting-type attacks is needed for this set to be successful, making Swalot and Pelipper good teammates. Really strong special attackers like Rain Dance Huntail just shred right through Wigglytuff, meaning dedicated special walls like Kecleon and Dewgong should be considered, and both appreciate the healing that Wish can provide. Wigglytuff can usually scare off physical attackers with the threat of Counter, making Spikes paired with it extra effective, and Roselia makes a naturally good partner to it. All that said, Wigglytuff actually fits quite well on heavy offense teams as a lure to blow back certain physical attackers, heal a teammate with Wish, and open the opponent's team a bit to aid in a teammate's sweep.

Wigglytuff plays a complete support role for offensive teams with this set, setting up a screen, passing a Wish to a teammate, and eventually allowing itself to be KOed to keep momentum going for its team. Safeguard is a neat alternate option to Wish that's uncommon in NU and ensures that Wigglytuff's teammate can't be stricken with status. Although it's kind of hard to set up both a screen (or both screens if you're crazy) and Safeguard all in one go, it can ensure the perfect setup conditions for a frailer sweeper that doesn't want to worry about status ruining its sweep, such as Swords Dance Kingler or Dragon Dance Pupitar. Thunder Wave and Body Slam are used to spread paralysis on the opponent's team to make sweeping easier for a teammate. While Wigglytuff is slightly outclassed by Metang with this set, as Metang has Explosion to get off the field quickly, Wigglytuff's higher special bulk and access to Wish and paralysis-inducing moves make it a decent alternative.

The EV spread provided best allows Wigglytuff to set up a screen and use Wish before being KOed. Maximum Speed can be run to allow Wigglytuff to outspeed as many defensive Pokemon as possible to better ensure it can get a screen up before going down. Protect can be used in the last slot with Wish to increase Wigglytuff's longevity and allow it to survive throughout the course of the match, but that creates a situation in which it's totally dead weight outside of providing screen support, which is not at all desirable in most cases.

As Wigglytuff is in a complete support role with this set, it shouldn't be the focus of a team. It won't do much in the way of filling team weaknesses and at most will only softly check some weaker attackers. Instead, it should be chosen as a way to try to guarantee a sweep with another Pokemon. Setup sweepers are a must to be paired with this set, meaning Swords Dance Mawile, Dragon Dance Pupitar, Rain Dance Huntail, and Sunny Day Bellossom are all ideal teammates. Wigglytuff tends to lure in Hitmonchan, so Pokemon that can take advantage of its Fighting-type moves, such as Venomoth, Haunter, and Chimecho, are also great teammates.

Wigglytuff has an absolutely massive special movepool, and it has a just high enough Special Attack stat to make a set worth using, particularly since its Special Attack is something that separates it from the other Normal-types in the tier. With this set, Wigglytuff acts as a decent wallbreaker, opening the opponent's team up to a special sweeper like Huntail later in the match. Ice Beam, Thunderbolt, and Fire Blast get incredible coverage in just three slots, hitting every Pokemon in the tier for neutral damage at worst. Thanks to this coverage, the last slot is open to a lot of moves, with Wish allowing Wigglytuff to provide team support or help itself, though it's hard to use without Protect. Fake Tears makes Wigglytuff's attacks actually pretty terrifyingly strong, usually forcing the opponent to switch and increasing the damage output to the opponent's team. Finally, Psychic can be used to nail Hitmonchan on the switch, and it is a nice way to more easily take out Swalot and Haunter.

Wigglytuff needs all the power it can get from a Modest nature, since base 75 Special Attack isn't overly impressive and the goal with this set is to punch holes in the opposing team. Maximum Speed is needed to outspeed as many defensive Pokemon as possible, as this set's main merit comes from surprising opponents who would normally be expecting a more defensive set. Blizzard and Thunder can be used for the sheer damage output they provide, but Wigglytuff gets enough mileage out of Ice Beam and Thunderbolt as it is, making the accuracy of the former two undesirable. Flamethrower can be used over Fire Blast for more accuracy, but Fire Blast is accurate enough compared to Blizzard and Thunder, and the extra power can come in handy against certain threats like Roselia, as Fire Blast guarantees a 2HKO against it where Flamethrower just misses out.

As for other move alternatives, a vast array of Hidden Powers can be used in the last slot to complete coverage on certain targets, such as Hidden Power Dark for Chimecho, Hidden Power Water for Fire-types, and Hidden Power Grass for Whiscash. Focus Punch can be used to get a surprise hit on Kecleon and Lickitung looking to switch in and absorb its special hits, further helping a sweeper like Huntail later in the game. If using Focus Punch, be sure to change the nature to Rash. Toxic is also a decent option to cripple special walls with recovery in extended matches.

Wigglytuff is extremely vulnerable to Hitmonchan if not running Psychic, making Chimecho, Haunter, and Pelipper great teammates to take advantage of the Fighting-type moves it'll be firing off. As Wigglytuff is actually rather frail without any defensive investment, most other faster, strong attackers are threats to this set, making sturdy, defensive Pokemon good teammates in general. Relicanth, Kecleon, and Lickitung can all provide a decent defensive backbone to support Wigglytuff. Pokemon that can make use of the surprise holes that Wigglytuff punches are great teammates as well, particularly special sweepers like Huntail and Calm Mind Sableye.
