A Sun Team with Refinement
A few months ago I posted a mediocre-ass sun team here to be rated. This team is a refinement of that arrangement, with many move changes and some pokémon changes as well. It has worked better than previously but still could use some improvement, so any feedback would be appreciated.

Elmer (Mamoswine) (M) @ Leftovers
Trait: Thick Fat
EVs: 252 Atk / 252 HP / 4 SDef
Adamant Nature
- Earthquake
- Ice Shard
- Stealth Rock
- Icicle Crash
Elmer: revenge killer, special wall breaker(ish) and support poké. Often comes to the aid of my team, staying strong in adverse weather conditions (sandstorm and hail) and even sometimes getting a few KO's along the way (screw you, Jirachi). To hit first, Shard, Earthquake to hit hard. Rocks to annoy and Crash to smash.

McCloud (Ninetales) (M) @ Leftovers
Trait: Drought
EVs: 252 HP / 4 SAtk / 252 SDef
Calm Nature
- Fire Blast
- Toxic
- Sunny Day
- Protect
McCloud: not quite as fast as his namesake but he can do some damage at least. After dicking around trolling with max SAtk and Solarbeam I decided to go with a more bulky set to keep my favourite alive (there's a reason he's shiny). Fire Blast over Flamethrower because really, the blasts rarely miss and hit a lot harder. Toxic to force some switches, while Sunny Day pisses off the sand inducers, whose storms I just removed. This usually results in an angry Earthquake though, which usually OHKO's after stealth rocks. Protect can defend against these quakes, but I can't switch the weather and stay alive in one turn, can I? More Defence EV's, perhaps?

Sofi (Heatran) (F) @ Air Balloon
Trait: Flash Fire
EVs: 252 SAtk / 4 SDef / 252 Spd
Timid Nature
- Fire Blast
- Hidden Power [Ice]
- Earth Power
- Flame Charge
Sofi needs a ladder to get up to her balloon, but when she's up there it's incredibly helpful. Can be used to predict against quakes or incoming fires. Usually ends up getting popped by the odd Stone Edge, however. Fire Blast deals with most things, though it seems to be my least used move...
HP Ice deals with dragons who want to get ragey at my team (yes, you, Dragonite) and has surprised a few opponents. Earth Power deals with...stuff (I can't remember what, Tyranitar iirc) while Flame Charge is there for set up. Seriously, you may mock, but the amount of times I've pulled off a sweep from just one charge is ridiculous. GOGO HEATRAN SWEEP

Harry (Heracross) (M) @ Choice Scarf
Trait: Moxie
EVs: 252 Atk / 4 Def / 252 Spd
Jolly Nature
- Close Combat
- Megahorn
- Stone Edge
- Earthquake
Meanwhile, back at the ranch, Harry is contemplating how to deal with everyone else's pokémon. This set is similar to Choiced Terrakion, except Harry deals with Psychics better. Basically, click a move and pain happens. After you kill one, more pain happens, thanks to Moxie. Megahorn deals with the aforementioned Psychics, while Close Combat hits other things. Stone Edge can muck up the birds in the sky while Earthquake is there for more coverage. Yes, Terrakion is faster and (marginally) more powerful, but I prefer to have a mega-powerful Bug STAB rather than X-Scissor. And Choiced, Heracross outspeeds most things anyway.

Victory (Venusaur) (M) @ Life Orb
Trait: Chlorophyll
EVs: 4 HP / 252 SAtk / 252 Spd
Modest Nature
- SolarBeam
- Hidden Power [Ice]
- Sludge Bomb
- Growth
Fairly standard Venasaur set here, Victory likes to do damage, and the more the better. After a x2 SpA boost, everything on this set kills something. Solarbeam is the STAB of choice, although maybe Giga Drain may be better to keep hurting things for longer, as Victory does like to die quickly. HP Ice deals with dragons (inb4 "HURR DURR Y U NO USE HP FIRE", I've tried that, I just got walled by dem dragons), while Sludge Bomb kills everything again with x2 damage. Will still go down fighting when raining after x2 Growth boost (no solarbeam? No problem! Sludge Bomb in yo face).

Starshine (Starmie) @ Life Orb
Trait: Natural Cure
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature
- Psychic
- Rapid Spin
- Hidden Power [Fire]
- Ice Beam
Starfish, starfish, in the game. Not perfect, but can be quite effective against certain threats. Psychic is the STAB of choice and helps deal with annoying fighting types on the opponent's side. No Hydro Pump because sun doesn't allow for pussy water fights. Rapid Spin keeps the rocks 'n' stuff (sorry, I've been listening to deadmau5 a lot today) off the field, while HP Fire is the killer. Opponent sees Starshine, sends in Ferrothorn. But too late! as he sees that his fateful iron-clad garden weed is nothing but ash on the floor. Also works with ferrous bugs! (although those tend to U-turn before I can do anything). Ice Beam deals with dragons and Tornadus-T (screw you, good luck spamming hurricane under sun, you bastard).
Summary
Overall, this team is effective against weatherless teams and hail teams. I think it's a 50/50 against sand teams, as although three of my pokés work under sand, it shuts down Starshine's HP Fire, and cuts Sofi's usefulness. Rain is the bane of this team, although it isn't unknown for me to beat them (see http://pokemonshowdown.com/replay/ou6144537), it's rare.
Thanks for any suggestions you may have!
