How about mine???:-
Weavile
Shadow Ball
Ice Punch
Night Slash
Brick Break
Get rid of Shadow Ball, it's literally utterly useless on Weavile as it can't Special Attack for crap, it has a 120 Base Attack, use it. Ice Punch, Night Slash and Brick Break are all good, replace Shadow Ball with X-Scissor and you even have a strong bug attack on board your team
with the power of the Pokemon to back it up.
Weavile's pretty fragile though, and will drop fairly easily, so make sure you focus on attack and speed - I'd say just EV train those instead of bothering with the defenses and build yourself a quick striker that can - hopefully - take down most of its problems in one go.
Empoleon
Steel Wing
Hydro Pump
Ice Beam
Surf
Surf and Hydro Pump together are a bit useless. Hydro Pump has the power, but lacks the accuracy and PP of Surf. If you were only planning to do one on one battles, I'd reccomend Surf over Hydro Pump - but if you plan to do 2-2, you should take heed that Surf will hurt your ally as well, in which case you may want to stick to Hydro Pump (PP should be less of a problem in a 2-2 format anyway).
Empoleon's Steel type betrays its stats - it's built as a Special Attacker, so using Steel Wing isn't much use - swap it with the Special Steel attack Flash Cannon. It's more powerful anyway, has better accuracy and is better suited to Empoleon.
Ice Beam is fine.
Abomasnow
Energy Ball
Blizzard
Rest
Hail
Use Empoleon for Ice attacks in Ice Beam, focus on Abomasnow's Grass type instead. Since Abomasnow has completely balanced Attack and Special Attack, you have a pretty big free range of attacks as neither will be better or worse on it, so try it with:
Abomasnow
Energy Ball
Giga Drain
Wood Hammer
Avalanche (Power will double to 120 if Abomasnow is attacked in this turn, it only has mehish defenses, so use it early and back it up with Leftovers or something)
Roserade
Magical Leaf
Petal Dance
Toxic
Energy Ball
Make Roserade more of an annoyer, it's got pretty unbalanced stats (favoured heavily in the Special area), but it's got good speed and you don't really need another main Grass type after Abomasnow.
First off, make sure it has Poison Point. You don't really want to be getting hit too much, but the ability is more useful in this case than Natural Cure.
Then try this moveset:
Giga Drain
Toxic Spikes
Ingrain
Leaf Storm
Giga Drain and Ingrain should ensure that Roserade lasts a bit longer than its weak Defense would generally allow, Leaf Storm is practically built for Roserade to kill things with and Toxic Spikes will help you with all the rest of your opponent's Pokemon. Could be good to send Roserade out first.
Gallade
Brick Break
Psychic
Toxic
Strength
Drop Psychic, Gallade is a physical attacker, not a special attacker. Use the practically invented for Gallade move Psycho Cut instead. Brick Break and Toxic are fine, but get rid of Strength and chuck in Close Combat instead - a good finisher.
Floatzel
Surf
Mud Slap
Ice Beam
Strength
Just drop Floatzel all together. Grab a Blaziken or something as said above and try that instead. A fire type thrown in would be a good idea overall.
