Okay uh. Bad pun for title aside, I've actually done a hail team before. After looking at http://www.pokemonreborn.com/forum/index.php?showtopic=3189, I've decided to make a brand new one. 
 
DAVE (460)  @ Leftovers 
Trait: Snow Warning 
EVs: 252 HP / 252 Atk / 4 Spd 
Adamant Nature (+Atk, -SAtk) 
- Ice Shard 
- Wood Hammer 
- Substitute 
- Sword Dance 
Weather-bringer. SD behind a sub and start sweeping. Leftovers will bring back the hp taken from Sub and Wood Hammer while Hail shaves off hp. Quite a solo-runner, actually. 
 
DAVE (121) @ Leftovers 
Trait: Natural Cure 
EVs: 4 HP / 252 SAtk / 252 Spd 
Modest Nature (+SAtk, -Atk) 
- Blizzard 
- Rapid Spin 
- Psychic 
- Surf 
Basic Starmie set. Rapid Spin to take away deadly Rocks and TS while doing decent STAB or Hail-induced damage. 
 
DAVE (478)  @ Focus Sash 
Trait: Snow Cloak 
EVs: 4 HP / 252 SAtk / 252 Spd 
Timid Nature (+Spd, -Atk) 
- Destiny Bond 
- Icy Wind 
- Pain Split 
- Spikes 
Ah, Froslass. Froslass is amazing, simply because it's uh... Nice art? Icy Wind to slow the opponent, ensuring Destiny Bond takes place faster.Pain Split and Sash makes a nice combo. SPikes is absolutely neccessary. My team can't be sweeping and meeting Sashes mid-game. Also Hail + Spikes = around 25% damage of opponent's hp. 
 
DAVE (473)  @ Choice Band 
Trait: Snow Cloak 
EVs: 252 Atk / 252 Def / 4 Spd 
Adamant Nature (+Atk, -SAtk) 
- Earthquake 
- Ice Shard 
- Superpower 
- Stone Edge 
4 speed for Speed ties. Other then that, Movepool for deadly POWs and 252 Defense since I don't really know where to put it. 
 
DAVE (471)  @ Leftovers 
Trait: Ice Body 
EVs: 252 HP / 252 Def / 4 SAtk 
Modest Nature (+SAtk, -Atk) 
- Wish 
- Protect 
- Blizzard 
- Toxic 
ALmost all Eeveelutions are deadly walls. DAVE Glaceon here is no exception. Wish + Protect does decent walling while Toxic and Hail shaves off Life points. Blizzard cuz STAB. 
 
DAVE (461)  @ Life Orb 
Trait: Pressure 
EVs: 4 HP / 252 Atk / 252 Spd 
Jolly Nature (+Spd, -SAtk) 
- Ice Punch 
- Ice Shard 
- Brick Break 
- Night Slash 
Basic Hit-and-Kill Set. Life Orb > My original choice for Ice Gem for more POW. Brick Break away the screens. Ice Punch for decent STAB and Shard for DAT 1 HP. 
Also, importable. 
I've never really done a RMT properly so if it's boring, please hate and flame. GG World~
