Tinted Lens: "Not very effective" moves have their power doubled.
Speed Boost: Speed increases one stage each turn
With two of the most threatening abilities in the game, its no wonder that Yanmega is ripping RU to shreds. With tinted lens, Yanmega spams Bug Buzz in the faces of opponents who watch their resists go to waste. With choice specs, Yanmega can 2HKO the majority of the metagame. Tinted Bug & fighting coverage gives perfect neutral coverage, so Yanmega's two other moveslots are usually occupied by U-turn for fleeing from special walls, and a filler.
Alternately, Speed Boost boost is like a better scarf without the drawback. After one turn setup with protect or detect, Yanmega outruns almost the entire meta. Otherwise fast Pokemon with rock moves can wipe the floor with him.
