Apparently I haven't answered this yet. Shame on me. This is the Electivire I'm using at the moment, and it works wonderfully.
If you know me at all, you know this is for VGC
Citron (Electivire)@ Lum Berry
Jolly | Motor Drive
252 Atk / 252 Spe / 4 HP
- Wild Charge
- Low Kick
- Ice Punch
- Rock Slide
This is my Electivire. The item, in my opinion, was the most difficult part of Electivire. I tried Choice Scarf at first, but I soon found that I needed both Ice Punch and Rock Slide to handle the opposing team, so I tried Lum Berry. It works like a charm, stopping WoW, Scald burns, and Swagger shenanigans. Motor Drive is a good ability when not running Choice Scarf, letting him absorb Thunder Wave and combat Discharge teams. Jolly and a 252/252/4 spread ensures maximum speed.
Wild Charge is STAB, used to hit Suicune, Milotic, and Politoed. Ice Punch nails Landorus, Thundurus, and Salamence. Low Kick deals with Heatran, Hydreigon, Bisharp, and a weakened Kangaskhan. Finally, Rock Slide picks up nice flinches and checks Talonflame and Charizard.
Electivire needs a lot of support. He really loves speed control like Thunder Wave and Tailwind. Also, he likes partners who either discourage Intimidators or check them outright. Wide Guard is also useful to let him avoid Earthquake.
Bzzt - Zzaat – ELECTIVIRE!
