And since we have been speaking about Yanmega so much recently, I figure I will share my favorite counter to it: Rotom-Fan:
Rotom-Fan @ Leftovers
EVs: 216 HP / 252 SpD / 40 Spe
- Air Slash
- Thunderbolt/Volt Switch
- Pain Split
As popular as Rotom-Mow is in RU, I fully believe the forme with the double ground immunity stands above. It's typing and natural bulk allows it to check threats on both sides of the coin, helped even further by Will-O-Wisp for threats such as Hitmonlee, Braviary, and Doublade, while still being able to dish out respectable damage. Pain Split further extends its lifespan, even more so if you predict them to switch into a high/full health 'Mon.
And for those wondering how strong he counters Yanmega:
With the IV's, the 40 Speed allows to outspeed base 90's, namely Moltres and Golbat. I personally use Thunderbolt over Volt Switch, both for the ability to 100% kill Yanmegas, and due to the fact I typically prefer to stay in.252+ SpA Choice Specs Tinted Lens Yanmega Bug Buzz vs. 216 HP / 252+ SpD Rotom-S: 152-180 (51.5 - 61%) -- 94.9% chance to 2HKO after Leftovers recovery
