By the way, how do you guys handle Volcarona and Reuniclus? These two can easily sweep through my teams :l
Offensive Volcarona often can't do too much, but ChestoRest is devastating. Tentacruel resists its STABs, but can't do much back other than Haze(which is illegal with T.Spikes IIRC) and Chandelure can't go through it if it does a QD.
I thought of Hariyama or Snorlax, but having no reliable recovery in Hail isn't very inviting.
No, Haze is illegal with Rapid Spin. You can use a SD Tentacruel, but...
Reuniclus is easy to handle with Bug Bite Scizor, but another weakness to fire in a Hail team is not good, Wobbuffet is a good counter of almost all Reuniclus variants and is also faster than the green blob.
Deoxys-D can easy handle CM variants with Taunt, Recover, Night Shade and Pressure, since Focus Blast and Psychic have few PP, but fails a bit against Trick-variants, burn damage with Hail damage, lefties tricked to obtain a Flame Orb, is not good.
Mew can do the same but without Pressure.
Latias can CM and roaring Reuniclus away has nothing to fear bar TR or Psychoshock versions.
Also don't forget Alakazam, out of TR variants, the worst Reuniclus can do to it is to take away its Focus Sash/Life Orb to give an useless Flame Orb.
Escavalier KOes it with CB Megahorn and it is slow, so the Sparta pokémon will be faster on TR, and Reuniclus has to fear Pursuit. Beware of Trick Flame Orb versions though.
The rare Gardevoir with Encore is useful too but maybe useless against something else.
Victini can work too.
Shedinja can work too, but only for laughing in a Hail team.
Also the unreliable Trick or Switcheroo. Pseudo-haze can work while. Disable also.
Encore from unexpected Pokémon. Haze on bulky waters also work.
The key is to cripple it or hitting it too strong to its special side specially with (Blizzard) Specs not giving it chance to hit back, settig up or Recover off the damage.
