This frail bird seems a stupid option as Uber supporter, in a metagame full of Thunder and Ice Beam, but with the right support is surprisingly strong. Its giant supporting movepool allows a lot of sets, but has one main set
[SET]
Name: PranksTaunt
Move 1: Toxic / Thunder Wave
Move 2: Taunt
Move 3: Roost
Move 4: Night Shade
Item: Eviolite
Nature: Calm
Ability: Prankster
EV: 252 HP / 248 SpDef / 8 Spd
[Set Comments]
- Dragon Dancers or Calm Minders can set up vs a Taunt'ed Ferrothorn / Lugia
 - Bad defensive stats, but Eviolite boosts them
 - Great immunities (Psychic, Ground) and resistances (Grass, Ghost, Dark)
 - Plenty of other options, thanks to its large, helpful supporting movepool
 - During Roost, hasn't the Electric and Ice weakness
 - Cripples easily many offensive and / or defensive threats, thanks to Taunt + Thunder Wave
 
[Other Options]
- Tailwind helps a lot slow sweepers, such as Groudon, Dialga, Giratina-O, Ho-Oh
 - Night Shade is for doing some damage, and to kill weaked foes
 - Perish Song avoids Baton Chains, but other than that is pretty useless
 - Torment is useful, but is really situational
 - Psycho Shift can pass burn, but passive damage is bad for a wall (outclassed by Sigilyph, though)
 - Haze stops set-up sweepers that are trying to get boosts while poisoned
 - Feather Dance + Toxic cripples Extremekiller, Bulk Up Palkia and such
 - Sunny Day or Rain Dance can be used to set up your weather again
 - Protect can rack up some Toxic damage
 
[Checks and Counters]
- Hates Thunder and Ice Beam
 - Almost every Arceus form (especially Electric) can take Murkrow down
 - Trick: every Choice Item (and Iron Ball) cripples it
 - Whimsicott and Thundurus, with Prankster Taunt, stop him
 - Mixed sweepers, such as Palkia, Rayquaza, Mewtwo, Arceus can dispose of him
 - Manaphy can easily set Tail Glows up and clean the Toxic damage with Hydratation-Rest
 
[Partners]
- Chansey, with Wish + Heal Bell, creates a great core that can stall out everything
 - Its worst enemies are Dialga, Specs Kyogre and faster priority users, such as Giratina-O, Rayquaza or Scizor. Everyone can kill them is a great partner
 - Baton Chains such as Amnesia Gorebyss help a lot, even if you will hardly switch
 - Dialga of you own (much more if Tailwind was used) can defeat Rain Teams with Thunder + Dragon Pulse + Earth Power
