While Yanma may seem harmless at first glance, it can actually deal quite some damage, having the ability to 2HKO many common leads in UU. Yanma has two great abilities in Compoundeyes and Speed Boost, increasing the accuracy of its moves and raising Yanma's Speed every turn, respectively. After two boosts to its Speed, Yanma is capable of outspeeding everything in UU. Yanma also has access to Bug Buzz and Air Slash, two reliable STAB options with good coverage in UU, as well as a useful support move in Hypnosis, which has its accuracy issues alleviated somewhat by Compoundeyes. Yanma does have its fair share of drawbacks despite these many advantages, mainly its paper-thin defenses and relatively shallow movepool. Also, Yanma's all around awful typing makes it 4x weak to the ever present Stealth Rock, pounding one more nail into its coffin. Nonetheless, Yanma is a very unique Pokemon who can be a real asset to a team that is designed to support it appropriately.

This is the only set Yanma can run without being harshly outclassed by another Pokemon in UU. Bug Buzz and Air Slash provide Yanma with two powerful STAB moves that hit Pokemon that don't resist them for solid damage. Air Slash also has a 30% flinch chance, which can come in handy once in a while. Protect allows Yanma to scout, beat Fake Out leads such as Ambipom, and gain a free boost of Speed if Speed Boost is the chosen ability. Hidden Power Ground is also an option, allowing Yanma to defeat Aggron, who would otherwise wall it, and hits Registeel and Regirock for at least super effective damage. Hypnosis is important so that Yanma can incapacitate a Pokemon that it cannot defeat directly. As for the choice of ability, Compoundeyes is very useful, increasing the accuracy of Hypnosis from 60% to 78% and Air Slash to perfect accuracy. Speed Boost is still a great ability, though, allowing Yanma to outspeed most Pokemon after just one turn, and defeat them before they can retaliate.

Other Options

U-turn is a decent option to consider, though given Yanma's vulnerability to Stealth Rock, it's not recommended. Psychic and Shadow Ball are alternate attacking options that offer good coverage, but are quite weak unless they manage to score super effective damage on an opposing Pokemon. AncientPower enables Yanma to almost assuredly OHKO Moltres, which is otherwise only 3HKOed by Air Slash, when run with a Modest nature. Lastly, Quick Attack can be used for picking off Focus Sash users that are faster than Yanma, though it should only be used in tandem with Compoundeyes, as it is a redundant move alongside Speed Boost.

Checks and Counters

Spiritomb is a great counter to Yanma because it can take any attack Yanma typically uses, can set up on it with Calm Mind, and with a RestTalk setup can take Hypnosis with ease. Spiritomb also has decent offensive stats, and with Yanma's frail defenses, it isn't hard for Spiritomb to remove Yanma from the battle with a timely Shadow Ball or Pursuit. Chansey and Registeel are also issues for Yanma with their impressive special bulk and ability to set up Stealth Rock, making sure Yanma will not be coming back into play safely. Both of the aforementioned Pokemon can also slowly wear Yanma down with Seismic Toss, or cripple it outright with Thunder Wave. Other than the above threats, Sleep Talk Pokemon or those with Insomnia and respectable bulk can counter Yanma. Any Pokemon that can take a hit from Yanma and strike back with a powerful STAB move will usually be able to defeat it once Sleep Clause has been activated.
