The only place that I really see Manectric flourish is in VGC 2014. With Lando-T scratched, T-tar and Garchomp nerfed, Cresselia non-existant and a majority of the meta-game shifting almost purely to physical, I'm seeing these things ALL the time.
So I wanted to have one on my team.
I found it has excellent synergy with Intimidate Scrafty-- latter causes switches between turns, and the mega-evolve causes intimidate to happen DURING the turn, after switches have occurred. Talonflame is also running rampant in that teir (is lured by Scrafty) and Manectric is an excellent counter with some bulk investment.
Gyarados is a good partner as well, either Moxie or Intimidate work well (I find moxie works better IMO), and it's coverage with Earthquake/Waterfall/Ice Fang is pretty spot on. With back and forth protects running, an earthquake/discharge spam could work nicely.
The problem is that it almost has to Mega-evolve immediately. You can't rely on Lightningrod, as the intimidate boost is its main draw.
Here's the Maney I'm using right now
Manectric @ Manectite
Ability: Static ==> Intimidate
EVs: 200 Spd / 252 SAtk / 56 HP
Timid Nature
- Flamethrower/Overheat
- Volt Switch
- Discharge
- Protect
I like the 200 Spd, to have 56 Hp, especially with Timid, it's quick enough to outspeed most of the VGC-limited meta-game (It's only the pokemon in the kalos dex) Max invest in special attack lets it hit hard.
Overheat can be used instead of Flamethrower, but it then causes Volt Switch afterwards to be incredibly predictable, and rather lackluster. I can't complain, I am using that over Flamethrower right now, but I switch frequently to see which I prefer.
Protect is a staple in the VGC game, for anyone unfamiliar.
