Behold the only good weather trainer
>Weather is set up by Abomasnow´s Snow Warning
>Pre gen 6 so that means it last more than 5 turns
>Plat gave her a Snow Cloak Froslass with Double Team and Blizzard (Gen 4 gives blizzard no acc check during hail)
>Snow Cloak: Raises evasion in a hailstorm.
Candice also has coverage against rock, fire, fighting and steel and a good balance of physical/special attackers
>Her 115 speed and 95 attack Sneasel has Aerial Ace
>Her 100 attack Piloswine has EQ, Stone miss and a beefy 120 bp Avalanche with its 50 speed
>Her Abomasnow has Water Pulse, Focus Blast and STAB Wood Hammer and also Avalanche for its 60 speed
>Her 110 speed Frosslass has Psychic and is immune to fighting
Mix that with the lack of fire types, the slowness of fighting/ground/rock types and their bad Sp.Def
