This is a team I've been using on shoddy for a couple weeks and it seems to do pretty good for itself sometimes. Other times it ends up fighting battles that seem lost from the very beginning so I figure that there must be some flaws somewhere that someone around here will be able to point out.
So here we go:
Bronzong @ Damp Rock
Ability: Levitate
EVs: 252 HP/152 Atk/8 Def/96 SDef
Relaxed nature (+Def, -Spd)
- Rain Dance
- Hypnosis
- Gyro Ball
- Explosion
Pretty standard leading bronzong, sleep something then set up RD, then either explode or switch (if someone on my team can easily switch in).
Ludicolo (M) @ Damp Rock
Ability: Swift Swim
EVs: 152 HP/104 Spd/252 SAtk
Modest nature (+SAtk, -Atk)
- Ice Beam
- Grass Knot
- Surf
- Rain Dance
My main special sweeper, can refresh rain in case it goes down. This guy's rain-boosted surfs are insane, and he rarely gets outsped so long as rain is up.
Jirachi @ Leftovers
Ability: Serene Grace
EVs: 252 HP/80 Def/176 Spd
Bold nature (+Def, -Atk)
- Wish
- Thunder
- Zen Headbutt
- Rain Dance
A mixed Jirachi, I put him in there to solve some problems I was having with skarmbliss. Can set up a quick rain in a pinch and then abuses serene grace with 100% accurate thunder to paraflinch everything to death. Also supports the team with wish (although for some reason, I rarely manage to successfully use a wish on anyone but Jirachi).
Jolteon (M) @ Choice Specs
Ability: Volt Absorb
EVs: 4 HP/252 Spd/252 SAtk
Modest nature (+SAtk, -Atk)
- Hidden Power [Ice]
- Thunder
- Shadow Ball
- Thunderbolt
Sweeper jolt, people never seem to expect this, makes a very nice late-game sweeper after all electric resists are taken out. He also makes a nice fall back in the cases where I can't manage to get RD off (since he's fast and hits hard with no setup). Also handy for absorbing those electric attacks people are so fond of aiming at water types.
Kabutops (M) @ Life Orb
Ability: Swift Swim
EVs: 32 HP/252 Atk/96 Def/128 Spd
Adamant nature (+Atk, -SAtk)
- X-Scissor
- Swords Dance
- Waterfall
- Stone Edge
This guy is a monster, the usual plan is to get him in on one of the fire attacks inevitably aimed at Bronzong or Jirachi, then SD and let him wreak havoc 'till it stops raining.
Donphan (M) @ Leftovers
Ability: Sturdy
EVs: 252 HP/6 Atk/252 Def
Impish nature (+Def, -SAtk)
- Rapid Spin
- Earthquake
- Ice Shard
- Roar
Provides spin support because otherwise, toxic spikes will end many of my sweeps prematurely. Also good for phasing setup leads (*coughNinjaskcough*) that bronzong would be otherwise powerless to stop.
My biggest problem here seems to be Blissey (CM Bliss especially). In fact, many defensive teams give me trouble since they tend to stall out my precious rain turns.
Other than that, my only issue is other weather teams who are far far too protective of their weather inducers. (which I think is actually an extension of my problem with defensive teams in general)
