Hail team feedback

Here is what I am planning on using on my hail team. I haven't EV trained some of them yet, so here are my UT/EV trained Pokemon I plan on using. This is my first weather team, so dont be too harsh on me!

Snover @Leftovers
Calm
Blizzard-Wood Hammer-Substitute-Leech Seed

for snow warning.

Frillish @ Rocky Helmet
Bold
Scald-Toxic-Recover-Taunt

Spin Blocker

Mamoswine @Life Orb
Jolly
Endeavor-Ice Shard-Stone Edge-Earthquake

Good physical attacker. I can't get one with Stealth rock though :-/

Kyurem @Leftovers
Modest
Focus Blast-Dragon Pulse-Blizzard-Shadow Ball

Good special attacker. He needs better moves though.

I was thinking a Walrein and a rapid spin/entry hazard Foretress, but I don't have them. Any suggestions?
