Overview

Yanmega is a rather overlooked Pokemon in OU due to its crippling 4x weakness to Stealth Rock. However, it has access to two of the best abilities in the game: Speed Boost and Tinted Lens, each of which is worth its own set. Yanmega can either gradually increase its Speed each turn with Speed Boost, which thus allows it to eventually outspeed everything in the metagame, or it can tear through almost anything in the tier with its unresisted STAB combination, thanks to Tinted Lens doubling the power of resisted moves. Base 116 Special Attack is not shabby, either, and Yanmega also has a decent base 95 Speed stat to put it to good use. While Yanmega is no Volcarona, Tinted Lens and Speed Boost are enough to set it apart and make it viable for use in OU.

Speed Boost

Life Orb Speed Boost Modest / Timid
Moveset EVs
~ Protect
~ Bug Buzz
~ Air Slash
~ Hidden Power Ground / Hidden Power Fire
4 Def / 252 SpA / 252 Spe

Yanmega becomes truly terrifying after a few Speed boosts, as it has a great Special Attack stat to fire off its decent dual STAB moves. Protect allows Yanmega to scout for dangerous moves from unexpected opponents while also giving it a free Speed Boost. Bug Buzz is Yanmega's strongest attack against neutral targets, and hits the many Dark- and Psychic-type threats in the tier for super effective damage. Air Slash takes care of the popular Fighting-types in the tier such as Conkeldurr, and is Yanmega's second strongest STAB attack. The final move depends on what your team needs: Hidden Power Ground destroys non-Air Balloon Heatran and Magnezone, while Hidden Power Fire hits Skarmory, Ferrothorn, and Scizor for super effective damage.

4 Def / 252 SpA / 252 Spe

Choice Specs and Tinted Lens is a formidable combination, especially with Yanmega's dual STAB. Heatran and Skarmory are no longer safe switch-ins since a resisted Air Slash can now 2HKO both, assuming non-specially defensive spreads. Hidden Power Ground is mainly filler, as Yanmega achieves perfect coverage in just two moves, thanks to Tinted Lens. U-turn works well with Choice Specs, as it allows Yanmega to scout switch-ins, though Yanmega must be wary about using U-turn too often due to the overbearing presence of Stealth Rock in the OU metagame.

Other Options

As previously mentioned, Yanmega has access to many other special moves such as Giga Drain, Psychic, Shadow Ball, and even AncientPower, but again, they do not provide more coverage or anything else for that matter. Hidden Power Ice has some merits on the Choice Specs set to hit Dragon-types such as Dragonite harder, but is rather useless otherwise. Yanmega has access to Roost, but has a hard time fitting it into its limited moveslots, and will often be hard-pressed to find an opportunity to use it; Yanmega would much rather attack than attempt to heal itself during the battle. Hypnosis is a decent option to cripple a would-be switch-in, but it has terrible accuracy and is thus not very reliable.

Checks and Counters

As with most special attackers, Blissey and Chansey are Yanmega's biggest counters; however, they are literally the only counters to the Choice Specs set. Specially defensive Heatran can take almost anything Yanmega can throw at it with the exception of Hidden Power Ground. Snorlax is a decent albeit uncommon check, but is 3HKOed by Choice Specs Bug Buzz and has no reliable recovery outside of Rest. The key to defeating Yanmega is to figure out which set it is running; if it is the Speed Boost variant, either Skarmory or Heatran can wall it, while if it is the Choice Specs + Tinted Lens variant, simply bring in something faster that can OHKO it. As mentioned throughout the analysis, Stealth Rock is the biggest threat to Yanmega, stripping away 50% of its health every time it switches in, so keeping Stealth Rock on the field is the best way to take care of it.
