Articuno is cool and all, but your moveset is messed up. I highly suggest Rotom-F over it.
Rotom-F @ Expert Belt
EVs: 4 Def / 252 SAtk / 252 Spd
- Pain Split
- Hidden Power [Ice]
Set up on a Pokemon who wants to status you or that you know will switch, and start the rampage. Expert Belt bluffs a Choice Item.
Audino is outclassed by Lickilicky, so go with Lickilicky.
Lickilicky (F) @ Leftovers
Trait: Own Tempo
EVs: 248 HP / 8 Def / 252 SDef
- Body Slam
- Heal Bell
Replace Camerupt for....CB Rapidash, who hits like a truck.
Rapidash (M) @ Choice Band
Trait: Flash Fire
EVs: 252 Atk / 4 Def / 252 Spd
- Flare Blitz
- Wild Charge
- Low Kick
Wow, he hits so hard. 'Nuff said.
Emboar is in RU. Not NU. A good replacement is CB Sawk.
Sawk (M) @ Choice Band
Trait: Mold Breaker
EVs: 4 HP / 252 Atk / 252 Spd
- Close Combat
- Knock Off
- Ice Punch
Knock Off hits Misdreavus switch-ins, if you're good at predicting.
We already have Rotom-F as a Electric type. Let's put Roselia as an Offensive Spiker, to help your team get some kills.
Roselia @ Eviolite
Trait: Natural Cure
EVs: 160 HP / 252 SAtk / 96 Spd
- Giga Drain
- Sludge Bomb
Yay for Roselia in NU! Wooot woot! Check dat sexy 100 SAtk!
4 SDef > 4 SAtk on Alomomola and Lefties over whatever you have xD
