Two similar sets with some minor differences...
(F) @ Leftovers
Ability: Snow Cloak
EVs: 252 HP/5 Def/252 SDef
Calm nature (+SDef, -Atk)
- Icy Wind
- Wish
- Charm
- Protect
---Move run down... Icy Wind is Stab and Lowers Speed on incoming Poke's to help easy Prediction, Wish supports the team, Charm cripples physical attackers, and Protect scouts and works nicely with wish. I've only tried her in UU and she works fairly well. Speed Ev's may be more beneficial to help outspeed more pokes, Protect can be switched with anything you want, and despite not having any Sp Atk EVs Icy Wind still hurts.
(F) @ Leftovers
Ability: Cute Charm
EVs: 252 HP/5 Def/252 Spd
Timid nature (+Spd, -Atk)
- Icy Wind
- Wish
- Heal Bell
- Charm
--- I use her for OU. A quick move run down... Icy Wind slows, Wish supports your team, Heal Bell is for status, and Charm hurts them physical attackers. Watch out for Metagross and his Clear Body ability. You can use T-Wave instead of Icy Wind but then you will be vunerable to Taunt and make sure you change your ability to Normalize.
