Rate my Hail Team

[00cnr]

Well my friend and I designed a Hail team and saw some success and some failures with it on Shoddy and we want to know how to improve the team. So, here is our team:

Abomasnow @ Leftovers

Relaxed
Snow Warning​

252 HP / 128 Def / 128 Sp. Def

• Blizzard
• Leech Seed
• Protect
• Wood Hammer

The reasoning behind this one is relatively simple, start up the hail for the rest of the team and stay alive to bring it back up when needed. Offensively, we put on Blizzard and Wood Hammer for powerful STAB moves. It also has Leech Seed and Protect to stall a bit with the hail while recovering HP.

Walrein @ Leftovers

Relaxed
Ice Body​

252 HP / 128 Def / 128 Sp. Def

• Avalanche
• Curse
• Earthquake
• Roar

This is here for walling purposes with the defensive EV spread and Curse to boost its defense and attack while slowing it down for effective use of Avalanche. Earthquake is for anything that doesn't levitate and especially Metagross, Lucario and other threats that are on the ground.

Glaceon @ Choice Specs

Modest
Snow Cloak​

252 Sp. Attack / 128 Def / 128 Sp. Def

• Blizzard
• HP {Electric}
• Hyper Beam
• Shadow Ball

This Glaceon is for special sweeping. With the special attack boost from the Choice Specs Blizzard Shadow Ball will hurt anything not resisting it. Hyper Beam is for a strong attack, but not solidified as part of the build. HP Electric for waters.

Weavile @ Choice Scarf

Adamant
Pressure​

252 Attack / 252 Speed / 6 HP

• Aerial Ace
• Brick Break
• Night Slash
• Ice Punch

Here we have a physical sweeper. Aerial Ace for Hercross, and fighting grass and bug in general. Brick Break covers normals like Blissey and Togekiss and the steels types. Night slash for ghosts and psychic like Gengar. Ice Punch for STAB.

Regice @ Leftovers

Sassy
Clear Body​

252 HP / 252 Sp. Def / 6 Def

• Amnesia
• Avalanch
• Curse
• Earthquake

Curse up and create the wall. Leftovers and Hail heal it while it sets up. Avalanche for STAB and Earthquake for anything that won't resist it.

Froslass @ Bright Powder

Modest
Snow Cloak​

252 Speed / 252 Sp. Attack / 6 Def

• Blizzard
• Destiny Bond
• Shadow Ball
• Thunderbolt

This one is mainly for those pesky fire-types. Destiny Bond and take it down with you, not much else going on with this set. Blizzard can do good damage, as well as Shadow Ball and Thunderbolt, all of which give coverage if Froslass needs to fight.

So, what do you think about this? Advice is greatly appreciated.
Thanks in advance!
