This a team that I've come up with (with some improvisition) and it does pretty well on PO, but I have a small problem (to be noted later). Anyway, here it is.





The Team in Depth

Whimsicott (F) @ Leftovers
Trait: Prankster
EVs: 252 HP / 252 Def / 4 SDef
Calm Nature (+SDef, -Atk)
- Taunt
- Leech Seed
- Encore
- Sunny Day
Whimsy... Trust me, this little girl has won me more games than I can count. Her last move is a tad unorthodox, but it deals with the weather-centered (rain and sand, mainly) metagame rather nicely (saved my life against a stallRein once, and got me several forfiets). I don't really miss the Substitute, though. This little girl has earned her place on my team.

Magnezone @ Air Balloon
Trait: Magnet Pull
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Substitute
- Thunderbolt
- Hidden Power [Fire]
- Flash Cannon
Standard. Captures Skarmory, Ferrothorn, Forretress... and kills. Deals with Waters nicely, too.

Haxorus (M) @ Choice Band
Trait: Mold Breaker
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)
- Outrage
- Dual Chop
- Earthquake
- Brick Break
For all of Whimsy's subterfuge, sometimes I just need brute force. Haxorus is my answer to that. Fairly normal.

Weavile (F) @ Life Orb
Trait: Pressure
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Pursuit
- Ice Shard
- Low Kick
- Night Slash
Weavile does not see much action, but she has her uses. Weavile dispatches Dragons, and, more importantly, deals with Magic Bounce users that make Whimsy SAD... Useful.

Volcarona (M) @ Chesto Berry
Trait: Flame Body
EVs: 4 Def / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Quiver Dance
- Rest
- Fiery Dance
- Bug Buzz
This is isn't a weather team, but it's nice to have someone who can capitalize on Whimsy's sun. Volcorona sets up death, doom and destruction in the sun, sweeping.

Starmie @ Expert Belt
Trait: Natural Cure
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Scald
- Thunderbolt
- Ice Beam
- Rapid Spin
Weavile and Volcarona loathe Stealth Rock, so Starmie comes in to save them. He's equiped with an Expert Belt instead of a Life Orb; I found he died too easily with the latter item, and he needs to stay alive.
Threats
This is my one problem, my one bane. It can be summed up in one word:
REUNCULUS.
I haven't really faced the fetus, but if Haxorus is dead, I am. If someone can help me fix the problem (preferably without changing Pokemon).
Anyway, that's it. Please analyze.
