Mienshao @ Focus Sash
Ability: Inner Focus
EVs: 252 Atk, 252 Speed, 4 HP
Nature: Jolly
-Fake Out
-Wide Guard
-Rock Slide
-Drain Punch
I think Drain Punch > Hi Jump Kick in this occasion in order to make use of the sash. If Focus Sash doesn't break on the first turn, then Drain Punch can replenish health to reactivate the Sash. Also there are a lot of Ghost types in VGC like Sableye, Dusclops and Chandelure, and if they switch in to a High Jump Kick, you will lost half your health.
Replace Malamar with:
Reuniclus
Reuniclus @ Life Orb
Ability: Magic Guard
EVs: 252 HP, 252 Sp. Atk, 4 Def
Nature: Quiet
-Trick Room
-Psychic/ Psyshock
-Focus Blast
-Protect/ Shadow Ball
OR
Chandelure @ Life Orb/ Expert Belt
Ability: Infiltrator
EVs: 252 HP, 252 Sp. Atk, 4 Def
Nature: Quiet
-Heat Wave
-Shadow Ball
-Trick Room
-Protect
Currently you have nothing that survives Hail damage except Abomasnow. I think Reuniclus would be a good option due to its bulk and high sp. atk. Malamar doesn't really have any stats that stand out, even though Contrary is nice.
Chandelure, while not surviving Hail damage, does have a STAB move that hits 2 opponents at the same time. It also has Infiltrator as its hidden ability, available in Friend Safaris, which will hit things behind substitute and both screens.
Expert Belt is an option for Chandelure since it'll take hail and Life Orb damage, while Reuniclus won't.
Abomasnow @ Abomasnowite
Ability: Snow Warning
EVs: 252 HP, 252 Sp. Atk, 4 Atk
Nature: Quiet
-Blizzard
-Giga Drain
-Ice Shard
-Protect
You could make Abomasnow physical > special since I'm suggesting Reuniclus, but then a physical run Abomasnow forfeits Giga Drain recovery. You also need to split EVs because Blizzard is the attraction in using Abomasnow.
Lickilicky @ Normal Gem
Ability: Cloud Nine
EVs: 252 HP, 252 Atk, 4 Def
Nature: Adamant (+Atk, -Sp. Atk, not speed)
-Protect
-Explosion
-Earthquake/ Rock Slide
-Power Whip
It'll seem strange at first that I'm advising a Lickilicky with Cloud Nine, but weather is pretty popular in VCG, especially with Thunder & Hurricane's accuracy in Rain, the sp. def from Sand for Rock types and Solarbeam & Chlorophyll in Drought. Lickilicky can be a good option to shut down other weather & take them out so Hail can be the main weather in the game. I believe that Drought will be the main problem in VGC'14 though, because of Mega-Charizard Y, which will override Hail because Drought will only activate with its mega-evolution.
If you can't get one with Cloud Nine, either go with Own Tempo or go with a Golduck.
As for Noivern, I don't see it surviving a STAB Ice Beam even with the Berry. Nor do I really see what Gengar is adding to your team. I think Noivern and Gengar suit Tailwind teams better, but I guess they could be good attackers if Trick Room runs out and Abomasnow & Reuniclus/Chandelure are out of the game. Also, Telepathy is useless for Noivern because you have no moves that will hit it. Go with Frisk or Infiltrator. I think you should replace either of them with something like Garchomp though, so you can use Earthquake and not hit your team mate. Still, maybe it would be better to go with another Trick Room setter like Slowbro.
What I would suggest is looking into is Escavalier, which has a good movepool but another double fire weakness, though it's got more chance of surviving a Fire attack with Occa Berry than Noivern does w/ Ice & Yache Berry. It's got really low speed as well, which means it can help on a Trick Room team, and also Overcoat, meaning it won't take Hail damage.
