Wynaut specializes in revenge killing Choice Scarf Pokemon and getting your Pokemon a free turn of set up. With its ability, decent defensive stats, and the CounterCoat combo, Wynaut is almost guaranteed to KO a Choice Scarf Pokemon using a resisted or neutral attack. Additionally, if a Pokemon is using a weak attack or stat boosting move, Wynaut can Encore it and switch to a teammate to get a free turn of set up.

Wynaut is one of the strangest yet most effective support Pokemon in Little Cup, due to its ability to trap almost any Pokemon with Shadow Tag. Using this set is very simple: First, you must send Wynaut in on an attack that it easily survives, or a non-damaging move such as Stealth Rock or a status move. You then use Encore on that move and proceed to do one of two things. Firstly, it can abuse Counter or Mirror Coat by simply using the correct attack to smack your opponent back for double the damage. This makes Wynaut a great revenge killer, and an excellent answer to dispose of Choice Scarf users; however, Wynaut's true strength comes in its second option. With the right move Encored, a Pokemon on Wynaut's team can potentially gain a free opportunity to set up. For example, if Wynaut Encores a Dragon Dance from Dratini, Wynaut can simply switch to a setup sweeper and attempt to wreak havoc. If it happens to Encore a move like Waterfall, a Pokemon such as Mantyke could come in and set up an Agility without taking any damage, and then proceed to sweep. Tickle is an excellent option in the last slot if you carry a Pursuit user on your team to take out specific threats, such as Bronzor. It also helps your other Pokemon take attacks while trying to set up. Safeguard or Destiny Bond are both good options in the last slot as well, depending if you would rather be able to be immune to the uncommon status effects, or attempt to take out the opposing Pokemon as they try to finish Wynaut off. Using Destiny Bond when you have low HP will start a mind game, allowing Wynaut to possibly Encore a non-damaging attack because your opponent may not want to KO their own Pokemon, but with Wynaut's pitiful Speed, this is not always going to happen.

Wynaut is also excellent at trapping and killing Choice Scarf users like mentioned above, especially the ever common Fighting-type variants. Since most Choice Scarf users do not have the ability to KO Wynaut, and since it doesn't have to take the turn to Encore, Wynaut can simply use Counter or Mirror Coat and KO that Pokemon with ease.

Wynaut needs to maximize its defensive capabilities, and can't use any attacks that rely on Attack or Special Attack, so bulky EVs are pretty much the only option. Before maximizing Wynaut's bulk, 12 EVs are put into Speed so that Wynaut can come in on Bronzor and use Encore before Bronzor can switch attacks. Wynaut gets 27 HP with 76 EVs and will obtain a total of 14 in both defenses after putting 212 EVs in Special Defense and 132 EVs in Defense with an Impish nature.

First and foremost, Wynaut needs to be paired with a strong set of setup sweepers to take advantage of Encore. These Pokemon need to have pretty good defensive synergy as well, because it might be hard to set up if Wynaut Encores an attack like Earthquake and you have no Ground-type resist or immunity. This means Pokemon like Gligar and Aron work quite well together with Wynaut, as Gligar resists the Fighting-type attacks and is immune to the Ground-type attacks that would OHKO Aron. Similarly, Aron resists Ice-type attacks which Gligar wouldn't be able to set up on. Like Gligar, Dratini would work well with anything that resists Ice-type attacks, because it has such a high damage output after a single turn of setting up Dragon Dance. With Tickle, Wynaut works great with Pokemon such as Taillow and Zigzagoon who need Bronzor removed. For example, if you send Wynaut in on something like Bronzor using Stealth Rock, you can Encore it and start using Tickle. After Bronzor is at -6 Defense, you wait until the Encore runs out and use Encore again. Then you switch to a Pokemon such as Stunky or Houndour to Pursuit Bronzor and KO it. This leaves your opponent open for a Taillow or Zigzagoon sweep.

Wynaut greatly appreciates healing in the form of Wish support. Wish support gives Wynaut the ability to take more hits, and thus KO more Pokemon with Counter and Mirror Coat. This makes Lickitung a great teammate for Wynaut, as not only does it carry Wish, it also is immune to Ghost-type attacks and lures in Fighting-type attacks for Wynaut to switch into.
