I often use Abomasnow as a lead to set up hail for my team. He can counter bulky waters and ice shard is useful priority vs the many ou sweepers that are 4x weak to ice.
I use leftovers for the item to try keep him around for additional hail creating switch ins, as this is his primary role.

Slowbro is on my team for his useful fire resist and as a physically defensive pokemon. As alot of my pokemon are slow they like to have thunderwave support, and with slack off and permanent hail slowbro can stall out alot of physical threats.

This guy has rock resist which is useful with my multiple ice types and is just a beast in OU. Mach punch helps alot vs the common threat Excadrill and he is a great counter to tyranitar that would try to ruin my hail.

I really like this dragon. He looks cool and in hail and with choice specs he is very hard to counter. He does alot of damage even to pokemon that resist his attacks (namely steel types) and has real high base stats for a OU pokemon.
He is 4x weak to stealth rock and i lack a spinner, so i tend to use Kyruem as a late game one switch in wonder.

I use heatran to absorb fire attacks aimed at my ice types and as a good counter to the steel types that try to take kyruems attacks.
I like air balloon so he at least temporarily loses his 4x ground weakness, and with his natural bulk he can at least survive one hit that way.
I choose timid over modest to at least speed tie with other unscarfed heatran.

The 'best' OU ice type pokemon has to find a way onto my team.
He's maybe not the best user of stealth rock, but this was the best way i could see to incorporate the move into my team.
I choose bright powder as i don't want choice band on my stealth rocker and because the chance of an opponents move missing is further increased along with snow cloak.
