Abomasnow
Nature: Sassy
Ability: Snow Warning
Item: Lum Berry
EV: 252 HP / 84 SpA / 96 SpD / 76 Spe
~ Blizzard
~ Wood Hammer
~ Protect
~ Leach Seed/EQ/Iceshard
Mixed attacker Abomsnow is sent out to get the hail rolling. I'm having trouble with it's last move because seed is recovery, EQ hits metagross, and iceshard is priority.
Sneasel
Nature: Jolly
Ability: Inner Focus
Item: Focus Sash
EV: 252 Atk / 252 Spe / 6 hp
~ Fake Out
~ Taunt
~ Protect
~ Counter/Ice Punch
It's clef's sneasel. It can fake out, taunt, while being immune to flinch which is just gravy. Counter is great if sash is up but Ice Punch let's him attack later on.
Weezing
Nature: Bold
Ability: Levitate
Item: Black Sludge
EV: 252 HP / 176 Def / 80 SpA
~ Thunderbolt
~ Fire Blast
~ Explosion
~ Pain Split/Will O Wisp
Weezing fills a lot of holes in my team. He is immune to ground and resist fighting which are problems for Ice Pokemon. Tbolt is for waters and Fire Blast is for steels that think they are being clever. Explosion is always nice to have. Pain Split let's him live longer, but Will O Wisp let's him cripple physical pokemon.
Lapras
Nature: Naughty
Ability: Water Absorb
Item: Leftovers
EV: 16 HP / 252 Atk / 16 SpA / 224 Spe
~ Dragon Dance/Curse/Protect
~ Blizzard
~ Earthquake
~ Waterfall
Lapras is an interesting pokemon that will be probably be coming out with Weezing. Blizzard takes advantage of the hail, Waterfall is for physcial STAB, and EQ is to hit metagross really. Dragon dance is always good to have, but curse would allow me to move the Spe EVs into Def. Protect is protect.
