OU Hail Team

[Azacin]

Yeti @ Leftovers
Timid
6 Def/252 SpA/252 Speed

Blizzard
Substitute
Leech Seed
Grass Knot

A staple in Hail teams, brings out hail, and causes 100% Blizzard accuracy. After he comes out, he can SubSeed, and hurt the opponent. with max speed and a timid nature, he'll be outspeeding most starters and seeding them.

Fat Fairy @ Leftoevers
136 HP / 252 Def /120 SpA
Modest

Calm Mind
Blizzard
Softboiled
Thunder

My Hail-version of CMbliss, but has Blizzard instead of Ice Beam and more SpA. Leftovers cancels out the hail. Thunder and BLizzard have increased chances of Status infliction, due to serene grace. A decent stall while she sucks health from the leech seed.

Acqua @ Leftovers
252 HP / 6 Atk / 252 Def
Relaxed

Stealth Rock
Stone Edge
Waterfall
Blizzard

Swampert is usually what I switch to from Abomasnow, Laying down stealth rocks and hitting with physical attacks.

FrozenWing @ Leftovers
252 HP / 96 Def / 64 SpA / 96 SpD
Calm

Blizzard
Roost
Heal Bell
Reflect

Articuno for healing others and lightening the physical attacks.

Drage @ Expert Belt
76 Atk/240 SpA/192 Speed
Mild

Aerial Ace
Blizzard
Dragon Pulse
Focus Punch

A dragonite to take care of my Fighting weakness. I used Pulse instead of Draco-Meteor since it doesnt lower my SpA. No life orb, the guy's already hurting from hail.

Forrtress @ Leftovers
252 HP / 120 Def / 136 SpD
Calm

Spikes
Toxic Spikes
Earthquake
Rapid Spin

Adds layers of spikes, Toxic Spikes, and Blocks any opposing spikes with Rapid Spin.

Obviously, this is a Stall team. It uses Hail, Spikes, Toxic Spikes, and Stealth Rock to wear down the opposition. Blissey, Swampert, Forrtress, and Articuno (Sorta) are made to wear down the opposition to prepare for

I can see this is going to take some work.

First off, scrap the Dragonite and Articuno. Replace them with Rotom-HandWalrein. The primary nature of Hail Teams is to stall. Meaning that you must try to protect your spikes and ultimately, stall. The Bliss is awful... Calm Mind Blissey is very outdated. A WishBliss could do way better in this team supporting your team very well :). Give Forretress Gyro Ball over EQ. Your team suffers from a huge MixApe weakness. Consider replacing Blissey with Latias for another fighting taker and a wish supporter that still special walls very well. Change Abomasnows EV spread to 252 HP / 84 SpA / 96 SpD / 76 Spe. Even though that is a spread for the mixed attacker it gives you some bulk that allows you to set up subs easily. You could dump the speed EVs too.
